This is very cool, congratulations! Just bought a sample pack. I have a few technical questions, if I may (or if you have a good blog post or document that can help, that would be amazing.)
I've been playing with RFID for a while. Is NFC different than RFID? On a different frequency than 132 KHz/13.56 MHz that I already have readers for?
Also, are there simple readers or breakout boards I can use to play with this (a la Parallax's RFID reader, or anything that could plug into my Arduino?) as opposed to buying a phone? Any suggestions for good readers or what the protocol looks like?
Also, out of curiosity (see, I'm a software guy, so often this stuff is a black box to me) did you all design and fab the tags yourselves? Or do you get them in bulk and then do your own customizations?
This is extremely cool stuff! I'm really excited about playing around with this!
- kul 15y agoHey memset, thanks! NFC is a subset of RFID which works over closer ranges (hence the term "near-field"). The other difference is it can be passive (i.e. the reader induces a current in the tag/sticker to read it, that's why the tag doesn't need any power). 13.56 MHZ readers should work. We're ordering cheaper reader-writers (~$50) and will put them on the store soon. In terms of sourcing, we get them in bulk. We basically tested all the suppliers for quality, speed, and are working with the best ones. Who knows though, buying a factory may be in our future. Have a read of our About NFC page: http://www.tagstand.com/pages/about-nfc http://www.tagstand.com/pages/about-nfc and our FAQ http://www.tagstand.com/pages/faq http://www.tagstand.com/pages/faq and if you have any other questions, let us know!
