Scenario 2: Preauthorization with Completion
A debit cardholder goes to a gas station and pumps $30 worth of gasoline. The issuer has configured an upcharge of $75 for gas pumps (MCC 5542).
The following are true:
- The original available balance is $1000.
- The gas pump uses a PIN to validate the debit card.
- The network is Visa Interlink.
Sequence of events
Events in the same step have the same timestamp.
- Visa sends a preauthorization request for –1.00.
- Galileo replaces the 1.00 request with a 75.00 upcharge, approves the request and puts a 75.00 hold on the account. The available balance is now 925.00. Galileo sends a
BAUT: authevent message. - When the gas has been pumped, the pump sends a completion for –30.00.
- Galileo backs out the 75.00 hold and replaces it with a 30.00 hold. The available balance is now 970.00. Galileo sends an
AAAU: authevent message. - Visa sends a batch file with the –30.00 transaction.
- Galileo backs out the 30.00 hold and posts –30.00 to the account. The available balance is still 970.00. Galileo sends a
SETL: setlevent message.
