Micro RWD H2 Protocol
The MicroRWD H2 version is a complete reader and tag acceptance solution for Hitag 2
RF transponders. The solution only needs a 700uH antenna coil connected and 5v DC
supply to be a fully featured read/write system. The module provides internal EEPROM
memory for holding lists of authorised identity codes, a manual override switch facility
and has LED drives to give visual indication of acceptance.
The RWD also has a TTL level RS232 interface that allows a host system to
communicate with the RWD if necessary, so that system features can be customised,
configurations changed and tag read/write data handled by the host system.

The Hitag 2 transponders provide 256 bits (32 bytes) of read/write EEPROM memory
arranged as 8 partitioned 32 bit pages. An area of 128 bits (16 bytes) is open for general
user data. The Hitag 2 transponders are configurable for different modes of operation
and the MircoRWD H2 version supports the high security PASSWORD mode only.
This feature uses two password codes stored both in the H2 transponder and the RWD
that are mutually exchanged when a tag is brought into the RF field; the tag is only
unlocked for read/write operations if these codes exactly agree.
The use of this Mutual Authentication process, encrypted communications and a pulsed
RF field ensures that the MicroRWD H2 reader system is very secure.
