Get customer identity

To identify a customer the ECR can initiate a CardAcquisition request. If loyalty match, a customer id is included in the CardAcquisition response, se the CardAcquisition section.

If no Payment request is initiated after the CardAcquisition request/response, the ECR must send and EnableService request with the TransactionAction component set to “AbortTransaction” to terminate the card processing and remove the card from the card reader.
