As far as I understand, passive RFIDs communicate backs to the
reader by consuming more or less power from the incoming radio
wave (please correct me if I'm wrong). How one would therefore
implement a reader using these daughter boards and gnuradio?
I have only worked with low frequency (125 kHz) RFID tags so far,
but this is what has worked for me.
[the explanations]
Cryptographic RFID tags require some particular signal (not just a
sine wave) to be transmitted by the reader. Details vary depending
on the kind of tag, so you'll need documentation or you'll have to
reverse engineer the signal produced by a reader.
Thank you very much that was very helpful. I'll give it a try.
