Most Excellent. Learned some basic/solid RFID related things today. Exciting! Thanks!!
Great to hear!
very clear and very helpful, many thanks for making this video for the technical community
Glad you liked it!
Great video. Very clear. Thanks
So glad it was helpful! Let me know if you are looking for any specific videos on RFID in the future!
may i know what pair of antenna and tag should i purchase if i wanna build a visitor anaytics system?
how did you do the connection between the rfid reader and software application for the read/ write
Im gonna be honest I just want an RFID tag in my wallet that sends RFID scanners to a rickroll is there a way to embed links?
Hahah, that's a pretty hilarious idea! You could do that with NFC tags, but then the person trying to read it would need to be only a few inches away. I don't think that there are genuinely many, if any, people out there trying to read your wallet, to be honest. Plus the chip is an EMV chip, which means they would need a specific type of EMV chip reader. The encryption level on credit cards, along with the complex algorithms makes it almost impossible to gain anything. The biggest problem would be hackers putting a fake credit card reader over a genuine one, like in this link below.

But, if it becomes possibly one day to encode a URL on an UHF RFID tag like that, I'll let you know for sure! Thanks for your comment!
yes you can do that, look up rfid on the modern rogue's youtube channel, and watch jason before and after getting his implant.
Peace...can the labeling be placed to any surfaces ( equipment, machines, parts and any combo ) ???
Hi, yes labels can mostly be placed on almost any surface but its important to take the type of surface into consideration. Some labels will not be able to mount on metal or glass, while others are made specially to do so. Take a look at this Guide to UHF RFID Tags, especially Chapter 7 called "Application Surface Materials". Thanks!

Superb !! well explained ,,,,,, Thanks
No problem!
very good!! How much information can be stored; are there other passive tags that can store more information ?
It really depends on the tag - below I've linked to an article specifically about the memory banks in tags and what you can expect. There are definitely high-memory tags that can be used to store more data than the typical 64 or 96 bit limit. Most of the time, people choose to use the low-memory tags and then associate any/all data on the back-end in a database. In a database you could have a table referencing the tag ID, and other tables capturing almost as much information as you care to capture (depending on software design, of course). For example, Tag 6854658961554 can be associated with "Steel Pipe number 45", which has been "recently inspected and cleaned on 6/20/2018". This pipe will be "due to be reinspected on 6/20/2019."
With custom software, any tag in the system could be read and immediately the software would populate the information from the database.

Hello, I am looking to turn my retail store into a smart store with smart shelves keeping track on product information. Could you advise best way to go about please
Thanks for the comment! There are a few different ways to go about this, but it would begin with outfitting the shelves with RFID hardware like a reader and RFID antennas and tagging each product with an RFID tag. The amount of RFID hardware would simply depend on the amount of shelves you are looking to turn into smart shelves. I have an article that I have written about Smart Shelving units and how to use RFID to outfit shelves, cabinets, or displays, here is the link - www.atlasrfidstore.com/rfid-insider/what-you-need-to-know-about-smart-shelving-units . In this article, there is a diagram of the RFID hardware in a shelving unit and information on what could be on the outside and what should be on the inside. Let me know if you have any further questions!
thank u for good information about rfid.
can i read multiple rfid tags in plastic box simuntaniously? if yes, how can and its name. i want to buy it if possible.
thanks
Ashok,
Yes you absolutely can - depending on size of the box and size of the RFID tags. Reading multiple RFID tags all at once in a specific space is exactly what RFID is used for, especially in applications like Inventory Management and Asset Tracking.
Because every RFID applications is different, there really isn't a 'one-size-fits-all' kit that I can give you a link to. The specific equipment and tags that would work for you depend on the size of the box, the size of the items, what material the items are made out of, and what your goal is. Below i have placed some links to read up on Inventory Management and Asset Tracking to get a better understanding of the applications. After that, I have placed a link to a Beginner's Guide so that you can learn more. If you have any specific questions, don't hesitate to reach out to one of our RFID consultants as well!

Question:
I am looking at developing a system for my work where I can place a RFID chip (Preferably in say a 3D printed plastic chit or "tag") and need it to store some fields such as: Operator Name, Date, Time, Asset ID, and a couple more misc fields.
I need to be able to write multiple times to these chips maybe once a month as the Operator performs maintenance. I would also need the operator to read the RFID unit to see when the unit was last serviced for instance.
I'm very new to RFID's and would love a pointer as to what type of very entry level writer/reader would accomplish this. I'm self funding this as a side project for my work.
thank you!
There are various different types of memory in UHF RFID tags, and each type of memory bank serves a different purpose. Please take a look at a blog post that discusses the types of memory in UHF Passive RFID tags:
blog.atlasrfidstore.com/types-of-memory-in-gen-2-uhf-rfid-tags
While it is possible to continually update and encode new information to an RFID tag, most applications use a database and reference number instead. Depending on the RFID tag that you are using, you might have enough memory space to encode the operator name, date, time, and asset ID to the RFID tag. However, most systems would simply encode a unique ID to the RFID tag and have that unique ID represent all of the needed information in an external database. For example, instead of encoding the RFID tag with the operator name, date, time, and asset ID, you could encode “00000001” to the RFID tag. Then, through software programming, you can perform an association between tag 00000001 and all of the needed information in your external database.
However, there are high memory tags that can host over 1k bits of memory if your application requires that data is stored directly on the RFID tag. Almost all of our UHF Passive RFID readers have the ability to encode data to a UHF Passive RFID tag. For testing purposes, you’ll may want to start with a low-cost, USB reader and a sample pack of RFID tags.
If you have any other questions, please let us know.
very late but here's your pointer: *
thanks.
can we track RFID tags using just WINCC (without PLC)?
Essi,
I'm not exactly sure what you are referring to in terms of WINCC, you would need an RFID reader to read tags. It looks like WinCC is a system interface, can you tell me a little about what you want to do?
Thanks very useful, I need one document preparation, Android app for RFID card,Milk wending machine ATM card reader, Android app and web application project documents
Baskker,
I do not have any web application project documents for these specific RFID applications. If you are looking for more information on each of these, I would look into possible overviews of those projects. Each of those projects though was created with a high level of cryptography and security measures, so there is probably no public information other than a short project overview.
Is there a specific question you were looking to have answered?
Thanks!
Can i read and write it with my iphone 13
I want to make my own smart wallet that does two way positioning...which tag I need that blinks the blue light?
Laurie,
RFID tags typically do not blink because that would require a lot of energy. The only RFID tags that have a battery are Active RFID tags which are usually about half the size of a smartphone, but thicker. Tags are usually similar to this - www.atlasrfidstore.com/smartrac-r6-dogbone-rfid-wet-inlay-monza-r6/ - and are thin pieces of plastic that you could easily put in a wallet. Can you show me the tag you are looking at and tell me what problem you are trying to solve?
Do you know if these RFID stickers would function in extreme cold temperatures? I.e -80C freezers?
Maryem,
Some tags can function in very cold temperatures - such as these tags that can be used in -50° C (www.atlasrfidstore.com/embeddable-rfid-wire-tag/), but generally most RFID tags are suggested to be in temperatures only as low as -40°C. There might be other available specialty tags that can operate at temperatures lower than -50°C, but they wouldn't be as thin as the labels in this video. They would most likely be larger with some sort of plastic encasing in order to survive in a freezer.
Does that answer your question?

Hi
I want to work on wood pallets, barcode numbers
But I want a program that generates barcodes so that each barcode is different from the other, and I install it on wooden pallets and use a system RFID
Please advise the necessary advice for the program used and the appropriate tags to install on wooden pallets
Thank you
Daoud,
A barcode printer could definitely be able to generate barcodes and you could set the printer software to generate different numbers. Are you saying that you want a label with integrated RFID tag but a barcode visually printed on the tag? You can definitely do this. This printer - (www.atlasrfidstore.com/zebra-zt411-rfid-printer-203-300-dpi-4-in-print-width-usb-serial-ethernet-bluetooth-uhf/) would help you do that and you can get a label similar to this, depending on the size that you require (www.atlasrfidstore.com/rfid-label-4x-2-for-the-zebra-r110xi4-zt410-420-rz400-rfid-printers/) and they can be placed on wooden pallets.
Are you going to need the tags to stand up to rugged environments, alot of damage, or any environmental concerns? If so, this label probably wouldn't be the best option, you will need a more rugged tag. Here's an article about some environmental concerns around RFID tags - www.atlasrfidstore.com/rfid-insider/factoring-environment-rfid-deployments & www.atlasrfidstore.com/rfid-insider/rfid-asset-tracking-maintenance-in-dangerous-environments/
What is the application?
Do yoy have any idea to identify voltage difference using RFID coz i am doing a project to identify the voltage difference on graphene i hope to use RFID tags but i have no idea how to identify voltage difference
Achintha,
RFID tags are not considered an effective way of measuring voltage differences on a material, but are primarily used for product identification and tracking. But doing a quick search, i came across this product with is a tag with a voltage indicator - www.farsens.com/en/2015/02/03/farsens-unveils-vmeter-battery-free-rfid-voltage-level-monitoring-tag/
Thanks!
Can I write a URL or a string with special characters to an RFID tag?
Hi!
Yes, special characters can be encoded to an RFID tag, but there are some limitations. For example, using an ASCII to hexadecimal conversion formula, you can encode only 12 ASCII characters to a 96 bit (i.e. standard memory size) Gen2 RFID tag.
For more information about encoding tags, please read the following article:
blog.atlasrfidstore.com/encoding-rfid-tags-3-things-to-know
Is it possible to determine the distance between the RFID reader and the RFID card?
Jensen,
Technically, this can be done, however, it requires a more complex software and algorithms. It can be done by measuring the RSSI which is the Received Signal Strength Indicator, or done using multilateration between three antennas using RSSI or another indicator like possibly round trip time (RTT) or time of flight (TOF) for instance. Here's an article on multilateration for more details. I know they discuss TOA or Time of Arrival in there. In addition, here is a blog post on RSSI.

if we need to tag a rfid to products with varying weights (eg vegetables that are sold by weight in each packet), will the tagging process take a substantial amount of time?
I think i would need more information on what you are trying to accomplish. Do you mean how long would it take to physically tag each item, or how long would it take to generate an EPC number and then use software to associate the random EPC number with the product's information and weight in a system?
Thanks!
@@atlasrfidstore "how long would it take to generate an EPC number and then use software to associate the random EPC number with the product's information and weight in a system?" yes this question!
I am trying to program an RFID to tell me the distance between the receiver and the tag and then input the distance into an Arduino board, is that something possible. if it is what tag and reader should i use.
Omar,
I don't think that is possible because the reader and tag are not able to calculate distance. However, the reader calculates an RSSI value each time it reads an RFID tag which could be used to roughly calculate distance if you assigned certain RSSI values (or ranges of values) a distance, based heavily on testing.
For example, if you read an RFID tag with a reader and were able to get a value of -40 (very close range RSSI value) you could use software to assign a -40 value with '1 foot or less' based on your tag's position during testing when your reader received that RSSI value. So every time your reader received a tag RSSI value of -40, your software would show you that that tag is within '1 foot or less range'.
It would take al ot of testing and software to assign distance values to those RSSI values, but that's the best way i can think of to try to calculate distance between the tag and the reader. If you had more than one RFID system or RFID antenna in the area, you could use triangulation between the RSSI values to try to more accurately determine the location of the tag. Here's some information about RSSI below -
www.atlasrfidstore.com/rfid-insider/rssi-role-rfid
Does that help?
May ask what is the data type that read from the RFID via its reader?
Hang,
I think that the answer to your question is binary bits, the RFID tag 'backscatters' bits to the RFID reader, which reads them, and translates that information typically in hexadecimal. Here is a great article on the different data formats and how to convert them into ASCII if needed.
www.atlasrfidstore.com/rfid-insider/rfid-tags-encode-versus-associate
I hope that answers your question!
Hi I want to deliver goods in baskets and I want only buyer can read it through their phone or through message etc to notify us that they have received the baskets. So which rfid tag should i use and how should i implement it?
Niz,
Seems like your applications would be best suited for NFC RFID so that your customers can use their smartphones (see eligible smartphones in this article: #9 - www.atlasrfidstore.com/rfid-insider/nfc-facts) to read the tags.
For your application, I think the best way would be to have an NFC tag on the basket that is encoded with a specific URL that is password protected. Upon purchasing, each buyer receives a unique password, say XXXX, and when the buyer taps the NFC tag with their smartphone, the URL is opened. At that point, the buyer enters the password they received when they purchased and are able to login. Once the unique password is input by the buyer, perhaps you can setup your software to take some action (i.e. send an email, send a message) that the user with the password XXXX has received their basket.
I suggest you read a lot about the ins and outs of NFC before purchasing anything so that you can completely understand what is possible with the technology. Below I am placing a link to a Hub Page full of information about NFC, at the bottom are several articles to get you started!

Hello, this reader can read the TID ?, There are any document / or video about it
Bernardo,
Great question! So all RFID readers can read the TID, but it depends on the reader and the software if it can display the TID number instead of the EPC number. For example, for the USB Pro Reader and the URA Demo Software you can read the TID on each tag if you read one at a time but you cannot read a handful or do inventory and only see the TID numbers and not the EPC numbers. Most demo software is like that. However, if you use an Impinj RFID Reader and the Speedway Connect software, you can change the settings so that when you read the tags, the software displays both the EPC and the TID numbers together. Impinj readers have a functionality called "FastID" which essentially helps Monza tags (Impinj's chipset) respond with their TID numbers faster than other tags.
Here's an article about FastID which is very interesting that shows you what is displayed - support.impinj.com/hc/en-us/articles/115000042850-Why-does-my-Monza-X-chip-backscatter-an-unexpected-EPC-

Does that answer your question?
Hi, can u help me plz, I have a variable uint32_t chipId; i want to write its content to an rfid block(for example 60) how can i do that?
Khalifla,
Can you give me more background on your hardware and RFID tag and what you are trying to do?
Thanks!
how would one know what to change on a universal studios rfid cup to get free refill?
Brad,
Haha, I wish I knew! My best guess is that they create a custom number or code and then lock the tag so no one can read it without that lock key. The lock key could be any number of digits so the possibilities are pretty endless. I'm sure since it's universal studios, they also have some sort of encryption for the code as well. I'm sorry we couldn't help - but be sure to let us know if you find a way!!
if i were to change rfid, will the old reader would not read it unless i program it to read with new rfid number or the original reader will still read the original number?
Thanks for your question
Can you give me more information and walk me through a specific example of what you are referring to? It would help me answer the question better.
Thanks!
Atlas RFID Store I have this rfid tag very similar to SunPass or eazypass rfid tag, that I have to have it on my windshield and my question is is there a way that I can disable it or change it’s id. I can’t remove it from the windsurfing my car ?
@@Michael-533 The problem with that is the end user agreement you signed to utilize that tag disallows tampering with it in that manner. You're gonna need a new tag.
Hi, Can you suggest any software to write on MiFare Cards?
I want to develop it myself in C#, bot couldn't get to go.
Kashif,
It all depends on the reader and frequency type - what reader and frequency range are you using?
I got the API from the vendor and now I am done with writing. Thanks for the reply.
Btw I was using PCR 310U
I have a question can an unauthorized person change the data stored inside the tag...
If they have the correct frequency reader and the tag is not locked, they can. However, you can choose to lock the tag memory banks and only people with the correct access code can read or edit them. Here is more information about locking tag memory banks - blog.atlasrfidstore.com/locking-memory-on-epc-gen-2-rfid-tags
How much data can store in rfid passive card what is the range of the antenna
Great question! So the amount of data that can be stored in an RFID tag all depends on the IC/Integrated Circuit/Chipset. Some IC's have 32-bits, some have 256-bits, etc., each one is a little different. A manufacturer chooses an IC and then chooses a tag antenna (which affects read range) to make a completed RFID tag. It's sort of like a computer setup, with a laptop and a connected monitor. There are hundreds of types of laptops and hundreds of types of monitors - so each combination will be a little different.
An average tag memory bank size is 96 bits, which equates to 32 hexadecimal characters OR 12 ASCII characters. If you are confused here - this is a great article to walk you through that - www.atlasrfidstore.com/rfid-insider/encoding-rfid-tags-3-things-to-know . If you want to browse different sizes of the most common IC's - I have a comparison guide you can look at here - www.atlasrfidstore.com/chip-comparison-guide .
In terms of range, I'm not sure if you mean the tag's antenna (tag read range) or the RFID antenna in the RFID system. Tags really vary in terms of tag read range, depending on the size of the tag's antenna. Larger the tag (tag antenna), longer the read range is a good principle. Some larger tags like Smartrac's Dogbone, can easily get 20+ feet, while small tags like Xerafy's Dash will only receive a few inches at best.
If you mean the RFID antenna's read range, that's mostly based on the RFID reader used and the RFID tag used. How much range were you hoping to get with a system?
So basically if u re write. A rfid card I can use contact less and chip. Or just contact less
Hi I have a question. Can we copy and rewrite a code from one tag?
Thanks for the question, can you be more specific? Are you asking about if you can have the same EPC code on two different tags? If so, that's completely possible, although it wouldn't help you identify one tagged item from another.
If you are asking if you can rewrite an EPC number at any point, absolutely. You can easily rewrite an EPC number hundreds of times if the tag is unlocked. Let me know if this answers your question!
can we write data into an empty rfid tag?
Absolutely, although no tag is completely empty. Tags are purchased from the manufacturer with a pre-encoded Unique ID number on the TID member bank, and most (if not all) tags also have a number on the EPC memory bank. Here's a post about the different memory banks - blog.atlasrfidstore.com/17-things-might-not-know-gen-2-rfid-tag-memory-banks
Hi does this still work in 2020
Theresa,
Yes, RFID works in 2020 and will continue to work long into the future because of the low-cost ability to track assets and inventory items. Below is a link to a few different RFID applications if you would like to learn more.
www.atlasrfidstore.com/rfid-insider/what-is-rfid-used-for-in-applications/
Thanks!
Can we say it is a one type of sensor?
Shreya,
If you mean can RFID be categorized as a sensor? Usually not, because if you look at what a sensor is defined as, it typically is something that detects and measures changes in the environment - so like motion, temperature, humidity, that sort of information. So you can actually buy RFID sensor tags that can detect environmental changes like humidity - here's an example here: www.atlasrfidstore.com/smartrac-sensor-patch-rfid-wet-inlay-rfmicron-magnus-s2/
RFID tags simply turn on and respond if an RFID reader sends our energy for them to do so - they just turn on and send back a number, not typically (unless you have a sensor tag) environmental information.
I hope this answers your question!
@@atlasrfidstore Thank you for your good information.
No problem!
nice
Thanks!
is the TAG can be unchageable, no body can change it.
and what can erase a RFID
Maxime,
Parts of the tag's memory bank are changeable, like the EPC Memory Bank and the User Memory Bank information. Only the TID number in the TID memory bank is not able to be changed. What specifically are you looking to erase?
Hello Sir, I was doing on a project which is related to RFID and the project was the priority seating of train travellers using RFID because of those seating may overtake to others by ignoring the needy people.
So, to prioritize those seating the disabled and pregnant women and other needy people might hold RFID card so, when they enter the train or the bus RFID reader will detect the card and blow off an alarm to notify the person that there is a needy person so the person will give the seat. so I have the problem with the software programming and how to connect all those things and get the final outcome. ,
what is the best way to proceed about the software program sir
Thanks, Sir.
Gaargusha, this would be possible, but each doorway on a train would need to be outfitted with an RFID reader and antenna to scan those RFID tags or RFID badges upon entering the train. The RFID hardware could be mounted above or next to the doors with an alarm, similar to this annunciator - www.atlasrfidstore.com/90-dba-annunciator/ hooked up to the system. Each RFID badge that has priority seating would be specially encoded with a specific encoding scheme and when a number encoded that way is read by the RFID reader, the software would then tell the annunciator to sound. Does that make sense?
