7.4 Pre-authorisation – adjust (top up/partial cancellation)
Pre-Authorisation Adjust is used to increase or decrease the value of the original
Pre-Authorisation transaction, where the expected value of the final transaction may
be higher or lower than the initial Pre-Authorised amount.
The expiry date of the original Pre-Authorisation transaction processed on
a Mastercard will also be extended.
A Pre-Authorisation Adjust can be processed in one of three ways:
1. Using the RRN from the Mastercard Pre-Authorisation transaction receipt,
within 30 days of the original Pre-Authorisation transaction.
(Note: The 30-day expiry may vary if a Pre-Authorisation extend has
been performed).
2. Using the RRN from the Visa Pre-Authorisation transaction receipt, within 1 day,
7 days or 30 days (depending on the type of business you have and how your
Pre-Authorisation is processed) of the original Pre-Authorisation transaction.
(Note: The 1 day, 7 days or 30 days expiry may vary if a Pre-Authorisation
extend has been performed).
3. Using the Search Transactions > Advanced Search function to browse.
The terminal can search the Pre-Authorisation transaction for 14 days.
(Note: If the pre-authorisation transaction is no longer present, use the RRN
to complete the transaction).
