I'm trying to find an RFID reader that is robust enough to simultaneously and consistently detect the presence (or absence) of multiple RFID tokens. I am writing to ask if anyone knows RFID readers that would be appropriate to detect the presence of multiple tags accurately and reliably? Thanks!
Just found the local library has capability to do just this! Plop down a bag of library books, it reads RFID tags on them all, no more scanning bar codes book by book.
E-mail and see if they'll provide some ingo

These sorts of RFID tags operate in the GHz range of frequencies and the readers are very expensive. I don't know of an affordable reader, please post back if you find one.
RFID devices in the 125KHz and 13MHz ranges can't do this.
