UHF RFID Tutorial Part 3 - Python Code

This video is the third and last of a three part tutorial series on how to read RFID tags using UHF-RFID reader and Raspberry Pi via UART. In this part of the tutorial, the python code necessary for the hardware to work will be revealed.

hi
i really enjoy part1 part2 and this one .. you have been describing the process very clear for me. Thank you very much.

[@tutorized4035]

Hello! I'm glad you found it useful! :)

[@karthikarjun1035]

HI, Thank you for sharing! Do we have any options to get RSSI value?

[@mabiovinicios4457]

Hello, is it possible to store the tags with the reading times?

[@MensuraVirtual]

I'm getting random readings of the same RFID tag with Chafon cf-ru5106 RFID reader and USB to RS232 converter, any idea?

[@TiagoMaricate]

Hey my fried, how can I get the entire data from tag? What is the RFID receiver model you used?

[@bobitsstibob4363]

Hello sir, is that the maximum range that reader can detect? It is just like 100CM

[@hariantoanto7534]

Sir, do you sell rfid reader active?

[@AljazJelen1992]

hi! first of all, very nice explanation! I subscribed! :)
a question ... what do you think its the max reading range?

[@tutorized4035]

Thanks for the appreciation. This type of RFID reader can read up to 10 meters.

[@agungwibowo341]

can this read multi tag simultaneously ?

[@ohbuibui9333]

can it do writing to tag?

[@k24tong4]

thank u.

[@tutorized4035]

Thanks for watching!

[@zulfadhli6740]

can the data be edited?

[@lelong8366]

Thanks for your share.
Have you tried to punch 2 tags at the same time? Do you know any solution to apply anti-collision? Thanks

[@tutorized4035]

Hi! Yes, I have, in fact, more than 2 tags are read at once using the device in the tutorial. However, I will still have to dig deep to address your second question. Thanks for the comment!

[@rabiatuladawiyah7299]

Hi, for the rfid, did you use external module reader or integrated RFID reader?

[@tutorized4035]

It's integrated already. The reader and antenna are in one device.

[@unboxingstories4633]

Hey thank you for you video. Can I ask if it can read multiple rfid tags at the same time? Like can it read 20 rfid at the same?

[@tutorized4035]

Hello there! Generally speaking, RFID readers can read dozens of tags per second but of course, the response time may vary depending on the make and model of the reader device and obviously the location of the tags. Thanks for the interest!

[@albertomassa9252]

Hi !! Do you think is possible to handle the same antenna reader with ESP32 ?

[@tutorized4035]

Yes, I believe so since ESP32 supports UART communication.

[@harashinotaki]

Hello! Can it read multiple RFID in front of the sensor simultaneously?

[@tutorized4035]

Yes, it can.

[@aandscrawfoski]

Hello are you offering lessons please?
Thankyou for you nice friendly videos.

Hello, I am following the tutorial with S-8600 RFID Reader. When I run the code it only prints "tag:". Upon Debugging I found that the variable "data" has "b' '" in it which makes the condition true, hence it prints only the word "tag:"
Secondly what does serial.read(17) does and what is 6:22 in format data? Is it format of a specific tag or all type of tags?

[@tutorized4035]

Hi Tayyab! Yes, your observations are correct. Firstly, "b''" exists because what is actually stored in the data variable are bytes. Admittedly, the code is not optimized as it only aims to show the tag ID readings from your RFID Reader. Secondly, the serial.read(17) is based on the length the unique TID of EPCglobal Gen2 tags which is in my case, 64-bit. Well, for basic troubleshooting, you may check if your RFID Reader is really able to read tags around it (does it beep when the tag is around?). You can also check if you have Python3 installed, if yes try running the python script as as sudo user because you might not have the right permission to access the serial port of your Raspberry Pi. Hope this helps! :)

Does this work for reading multiple tags at once?

Yes, It does.

[@sevikharvarid9893]

Hi, thank you for this tutorial video. i've tried this code but when i display the output it shows different tag value on the same RFID.. can you explain why ?

[@tutorized4035]

Hello! Sorry, I've been busy the fast few months. My hunch on that question is that, some other tags on the background are interfering with the readings, so you might want to consider keeping them in a safe distance when you test them individually .

[@ronaldkaluba1480]

How do I make the same project with arduino?

[@vincentvargas9251]

if y'all looking for rfid reader that can read on arduino. reply to this comment for the price. i'll also give you the circuit and the code for the rfid.

[@julianarango6082]

How much does the reades that you used cost?

[@tutorized4035]

Shipped from overseas to the Philippines, it cost around 10,000 Pesos.

[@mariasyahirah2163]

Hi, thank you for sharing this tutorial video. I am following the tutorial with UM202 reader module. When i run the code, it will print many data/id tags (around 12-15) with different number. And i realize that the data/line number 9 is printed the correct id. Do you know why is this happening?

[@ayoubsd5110]

I think the code is not correct.

[@tutorized4035]

Try to determine first the Electronic Product Code (EPC) bits of the UHF tags you are using, so you can edit the code accordingly. Particularly on "ser.read(X) and "data[6:22]" at line 18 and line 20, respectively. Best of luck!

[@ayoubsd5110]

Hi sir, when I run the code, it will print many id with different numbers.do you have a idea about that?
