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.
