To charge the card after an AUTH transaction, perform a POSTAUTH transaction as shown in Section
6.4.5 on page 73.
For example, a cardholder is traveling and needs to book a room several days in advance. The
cardholder calls the hotel and the hotel advises the cardholder to authorize a certain amount of
money in advance to the hotel to book the room. The cardholder provides their credit card
information to the hotel and the hotel performs a credit pre auth using the S920 terminal.
1. The merchant initiates a credit AUTH transaction using the S920 terminal.
2. The merchant enters the transaction amount.
