    We have started to use them on our project: Automated Library Management System, wherein we would be using the tags for identifying book, tracking, security checks, smooth technical processing of the books, easy to locate books in library and also certain membership management techniques for library users.

    Is there a follow-up video to this one? I just bought a 100 pack of cards and several readers I want to make ap roject out of. I want to try and use it to play a trading card game with another player over the internet using real cards and a placemat with readers embedded in it

    Hi,Thanks for your video , I have a question about tags! does each RFID system has own tags I mean every company writes own data to tags and it can not be understand by others?

    Thinking of getting a receiver module for GM keyless entry (like my Cadillac CTS uses) then , when I sit down at my computer it will unlock automatically using my car’s keyfob without having to remove my car keys from my pocket—get tired of typing in passwords
