Technical Details
Wiegand Reader
Reader is a 26bit Chinese special. MSB and LSB are parity bits, the remainging 24bits are the LSB of the RFID token. Couple of gotcha's with this reader. Numeric key presses are sent without parity and are only 16bits. Also buzzer lines or status led cannot be held low when trying to read data from the reader.
