HITAG 2 Transponders
Product Specification 3.0
July 2006
5.2.2 Status Flow
After entering the RF-field the transponder waits for a command to start the authentication.
After issuing this command the mutual authentication takes place, followed by read- and write
commands.
In password mode the data transfer occurs plain, in crypto mode data are encrypted.
The halt mode can be entered for muting a transponder.
If the transponder is configured in one of the public modes, these modes are entered
automatically after a certain waiting time and data pages are sent cyclically to the read/write
device.
By issuing the command to start the authentication during the waiting time also public mode
transponders can be brought into the authorized state.
