Figured this was a bit better suited to this forum, I'm thinking of getting a cheap usb RFID reader/writer off of ebay as well as some of the business card style RFID cards.
I am not sure how they go about programming with these, or if you can even program them the way I am thinking, but I am wondering if you can actually write some text data to RFID cards/tags, I don't know how many characters you could get it, it is only 264 bits available in some of the ones I found, but being able to fit a few bits of info, or even a few sentences, would be pretty cool, if it would just spit it out as plain text when hooked up to similar readers. (could even encode it somehow as well)
Anyways, I figure there should be some people here who have messed around with this, and maybe even done the same thing, and might be able to point me towards the type of reader/writer I would need, and give a bit of insight as to how you program them on a PC. (can't see any software mentioned, and hell, half the cards that say "writer" in the title then say it's a reader only)
I had thought about doing the same with magstripe cards since those are cheap, but the writers are ridiculously expensive, and when you compare them to RFID they are insane. Tried to find why they haven't come down and all I found was a post I made ages ago in general chat with no replies.
edit: seems like I would need to go for 13.56 mhz cards to be able to write to them, and this seems like it might be a decent little kit to start playing with them.
