Actually, visiting that link 24U specifies explicitly that they do RFID read/writes with their plugin from filemaker.
Thanks for the link. Great site!
We're encoding the RFID chips via FMP to a Zebra printer. We're reading the encoded tags with a NordicID reader and importing that data into FMP and comparing that data with a "known" inventory database.
I don't believe the Phidgets reader can work for this purpose at the moment.
