The Gemalto PKI PIN Pad has built in timeout whilst as a connected device, the purpose is not for power saving, but due to security reasons.
These timeouts may happen if a long period of inactivity is detected whilst a user input is requested. For instance:
- During a PIN code seizing, when entering digits or OK / Cancel validation is expected,
- During a Message display, when entering OK / Cancel is expected.
The timeout defined in the firmware of the reader is set to 60 seconds. When a timeout happens, it simply cancels the current operation, which must be resumed from the start if needed.
