Scenario 1: Authorization with Settlement
A debit cardholder goes to a restaurant and the meal totals $45. The cardholder adds a $10 tip to the receipt. The following are true:
- The initial available balance is $1000.
- The merchant uses a signature to validate the debit card.
- The network is Mastercard Banknet.
Sequence of events
Events in the same step have the same timestamp.
- Mastercard sends a preauthorization request for –45.00.
- Galileo approves the request and places a 45.00 hold on the account. The available balance is now 955.00. Galileo sends a
BAUT: authevent message. - Mastercard sends a batch file with the –55.00 transaction.
- Galileo backs out the 45.00 hold and posts –55.00 to the account. The available balance is now 945.00. Galileo sends a
SETL: setlevent message.
Note
Because the settlement amount is higher than the preauthorization amount, there is a risk that the tip could drive the account negative. See Upcharges in the Authorization guide for a way to mitigate this risk.
Transactions
These tables show how the transactions are represented by various Galileo systems. For an explanation of the trans_code field, see Classifying transactions in the About Transactions guide.
