I need to make a home inventory of the numerous items I have in my home.
DIY tools, cameras and various accessories, just to give an example, which I have inside a wardrobe and in some boxes.
It involves cataloging around 300 objects with RFIDs.
To create this inventory I purchased the best used RFID reader on the market, the Zebra RFD8500.
The problem I have is that I don't know how to program the RFID tags (associate the unique number of the RFID tag with the name of an object or photograph), I don't know if I have to buy management software or if the 123 rfid mobile application that I downloaded is sufficient for my purpose.
My need is very simple, I don't have to move goods, I just have to catalog some objects to be able to find them.
You can help me?
