I bought an Eval kit for an RFID module. The reader detects the card included in the kit just fine, but it can't find a separately bought, completely blank RFID tag. The reader is 13.56MHz and supports ISO 14443B. The Tag is 13.56MHz and ISO 14443B.
The RFID reader is the DLP-RFID2-EDK https://www.dlpdesign.com/rf/dlp-rfid2-ds-v114.pdf
The software is a TI demo GUI called TRF7970A_GUI_WIN7_11_2013
Is there a special initiation process for new tags? or does it have anything to do with the security features of that specific tag?
EDIT: from http://ww1.microchip.com/downloads/en/DeviceDoc/Atmel-8672S-CryptoRF-AT88RF04C-Datasheet-Summary.pdf Section 2 Communications "The IC includes an integrated tuning capacitor, enabling it to operate with only the addition of a single external coil antenna."
Does that mean these tags need you to solder on an antenna?
