Supported Transponders – Philips Hitag 2
  125 kHz, 256 bit (32 byte) read/write passive RFID transponder, of which 16 bytes
are available for user storage.

Memory is organised as 4-byte Pages.
Page 0 is a factory programmed 4-byte unique serial number (UID).

Hitag 2 uses a dual PASSWORD authentication system to allow access to it’s
memory. Dual 32 bit and 24 bit Passwords are stored on the tag and corresponding
Passwords are stored in the Reader.

Full access to the tag is only possible if these Passwords are correct, making Hitag 2
a very secure tag type.
