Review on YARONGTECH MIFARE Card Reader RFID 13 by Tylin Meyer

Reads at least two different types of RFID cards (must be 13.56MHz). It's easy to reprogram to return all 14 hex characters, which is what you need when you need unique data. If you connect directly to data entry fields, the HID interface works fine. I need to read from a background program, so I had to modify udbhid-dump (Linux) to create a reading routine for me.
