I’d like to begin by saying that I am new to Arduino and even newer to RFID. I’ve seen RFID readers from ID Innovations and Parallax, however, I’d like to know if there was a RFID IC I could use as a replacement. For example, I’ve been looking at TI’s TMS3705, NXP’s HTRC11001T, EM Microelectronic’s EM4XXX series, or something from Atmel, although, I am unsure if these are the appropriate ICs. My basic understanding is that as long as these ICs have power, ground and a data I/O they should be able to read the transponder. Or will I need to load software onto these chips first to work (i.e., can these be used “out of the box”?) Also, from what I’ve read from some of these companies, they need a basestation, which I assume is a microcontroller and would think the Arduino would be appropriate enough.
As for their application, there is not much specifics to it yet, more so experimenting. What I do have in mind is using a 125-135kHz transponder, preferably with anti-collision.
I’ll make sure to update this thread with additional questions, comments and information as I come across it. If anyone has used these, I’d enjoy hearing about it as well.
