GAT Access
The GAT Access is technically only capable of reading locker information (writing is not possible). For the reader to retrieve the information, a carrier configuration must be stored on the device. To add a carrier configuration, click on the corresponding menu item and select "Add carrier configuration."
Configure Mifare Transponder
Select the appropriate transponder type.
For Mifare transponders, you should also select the segment type (currently, only Ganter segments are supported). If you want to prevent checkout when a locker is still locked, activate the corresponding checkbox.
Configure Legic Carrier
For Legic carriers, select the transponder type Legic. Here too, only Gantner segments are supported. If you want to prevent checkout when a locker is still locked, activate the corresponding checkbox.
Save Settings
Don't forget to save the settings by clicking "Save."
Edit or Delete Segments
To edit or delete the created segments, click on the corresponding three-dot menus.
