Trying to find out who’s doing what with GnuRadio regarding RFIDs:

  1. Newell Jensen (UniWashington) wrote this on his blog, but no code yet. It’s a continuation of the work of Michael Buettner, done (presumably) at Intel’s WISP project, the results of which are published here (however, they seem unrelated to gnuradio). Read also this paper.
  2. Harald Welte is also working on RFID, and also in OpenMRTD. These too seem to have nothing to do with GnuRadio
