Actuator test
ID: 191483
State: Released
When DHS receive the frame NFC_01 with signal Stellgliedtest_NFC set, the DHS shall perform
the actuator test requirement as described below :
1. It shall turn on the antenna for at least p_t_tgs_actuator_test s and look for an external
device with RF discovery polling rate as short as possible
2. If it finds an appropriate counterpart (NFC-A Type 4), it shall activate and send the SELECT
command.
3. It shall feedback the result by changing the parameter "authenticated NFC-counterpart"
The DHS Application shall execute the acutator test (when requested) at any time regardless of
the Misuse or K15 State and ESM.
It is required that the field is turned on during the complete duration of the actuator test.
