Credit Card Transactions; Credit Auth - PAX S300 User Manual

This manual highlights those cases where the options may differ based on certain tender types, such as
credit, debit, etc. and certain transaction types, such as sale, return, void, gift, etc.
For every transaction, the ECR sends the transaction
message, including the EDC type, transaction type and
transaction amount to the terminal and the terminal is
initialized.
Most retail transactions do not allow for a tip amount
on the receipt. However, there are exceptions, such as
hair salons, nail parlors, etc. In those cases, the system
can print a tip line on the receipt and the terminal may
prompt for an operator or server ID. These applications
are multi-merchant applications and contains an "MM"
in the name of the app on BroadPOS MarketPlace.
Printing a receipt (or other items printed on the
receipt) are a function of the ECR, not the S300
terminal.

6.5 Credit Card Transactions

This section details retail 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 merchant 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.
6.5.1.1 Credit Auth (Over the Phone)
1. The merchant initiates the transaction using the ECR and requests the credit card information
from the card holder. When manually inputting the card number and expiration date, the
terminal may prompt for Address Verification System (AVS) and or CVV settings.
