Secured device manufacturing self-test

Abstract:

A payment terminal can have a secured test mode. Interfaces of the payment terminal may be secured via various techniques. Self-test input touch inputs may be provided at a user interface to initiate device self-tests. The payment terminal may perform the self-tests, and generate a machine-readable output including device information and results from the self-tests. The payment terminal may display the machine-readable output for scanning by test equipment.
