Device self-calibration and component resolution
Events generated from a terminal are analyzed and a problem associated with a component peripheral of the terminal is identified. Operations and parameters to the operation are obtained to resolve the problem. The operations and parameters are encoded in a code along with security information. The code is provided to a mobile device. The mobile device provides the code back to the terminal. The terminal verifies the security information from the code and decodes the operations and parameters. The operations with the parameters are processed to resolve the problem on the terminal, and the security information and code are logged for auditing.
