7.5 Credit Card Transactions

This section details restaurant credit card transaction types.

Credit Auth

An Auth transaction (card authorization, pre-authorization, or preauth) verifies an electronic transaction
initiated with the credit card and holds that amount as unavailable until the restaurant clears the
transaction (settlement) or the transaction hold expires. The Auth transaction does NOT charge the
credit card but reserves the requested amount and places a hold on the card holder's open-to-buy.
To charge the card after an Auth transaction, perform a POSTAUTH transaction as shown in Section
6.5.3. To cancel an Auth transaction, perform a VoidAuth transaction.
1. The restaurant initiates transaction using the ECR.
2. Card holder inserts, taps, or swipes card or device and is asked to Accept or Cancel the PreAuth
transaction.
3. If the card holder cancels, the terminal returns to the idle screen.
4. If the card holder accepts the transaction, the system prompts for a signature.
5. The card holder signs in the signature area and has the option to Accept, Clear (clears signature
field), or Cancel the signature prompt. In this case, the card holder signs and presses Accept.
