No-Show is a service that allows the card acceptor to charge the cardholder's account if a cardholder fails to cancel or use a reservation for car hire or a room rental.
Arkos allows additional features that are not documented in the nexoFAST 3.2 documentation. One of these features is it to allow No-Show transaction without looking for the transaction in the transaction log.
This is essential for terminal that are configure to do pre-auth without transaction log.
