Mce.Request

This command is used to check if a Mobile Card Emulation (MCE) device (usually a smartphone running a particular app) is currently presented to the reader. As long as an MCE device is detected, the command returns the serial number that has been transferred from the device to the reader.

If no MCE device is detected, the status code Mce.ErrNoTag will be returned. In case MCE is not enabled on the reader, Mce.ErrDisabled will be returned.
