Upon successful transaction reversal, the device will always print a
receipt with information on the reversed transaction.
Sample transaction reversal receipt:
A PREAUTHORIZATION is an operation where the merchant reserves
(locks) an amount on the card for an upcoming transaction to be
completed within a predened time set by the bank. If the transaction
is completed successfully, the device issues an authorization code
to be used later for the SALE COMPLETION operation.
This service is available upon additional merchant approval by the
bank.
