7.1.5 Acquiring Transactions
Acquiring
7.1 Acquirer Obligations and Activities
Before acquiring Transactions and on an on-going basis thereafter, the Acquirer
must test to ensure that appropriate procedures, technology, software,
hardware, and control devices are in place to properly complete Transactions,
without undue risks to other Customers, Cardholders, or Merchants.
The Acquirer must ensure that the Merchant informs the Cardholder that the
Merchant is responsible for the Transaction, including the goods or services that
are the subject of the Transaction, and for related customer service, dispute
resolution, and performance of the terms and conditions of the Transaction.
It is the Acquirer’s responsibility to ensure that all channels that process
Transactions comply with the Rules, and the regulations, policies and technical
specifications of the Corporation. The Acquirer must perform tests, both initially
and on an on-going basis to ensure compliance with this Rule.
NOTE
Additional regional Rules on this topic appear in Chapter 17, “Europe Region,”
of this rulebook.
7.1.6 Certification Process
Before acquiring Transactions, Acquirers must follow the procedures for testing
and certification of their connection(s) to the Interchange System, as agreed
by the Corporation from time-to-time and published to Customers. Thereafter,
Acquirers must upgrade their connections as necessary, to ensure continued
compatibility with the current technical specifications of the Corporation, and
must certify such upgrade, if required.
7.1.7 Transmitting and Processing Transactions
Acquirers must maintain, directly or indirectly, a functional twenty-four
(24)-hours-per-day operating connection to the Interchange System.
Acquirers must transmit all Transactions they acquire to the Interchange System,
in accordance with the applicable Standards. Refer to Chapter 9, “Processing
Requirements,” for additional information.
In addition to all other message format requirements, Acquirers must transmit
within each Transaction record the Terminal location description, the name of
the Customer that owns or sponsors the ATM, the Terminal or Merchant address
where the ATM is located, and the Terminal identification (which must be
unique) within each Transaction record. For additional information refer to
the technical specifications.
If there is no agreement for the transmission and processing of domestic
Transactions, Acquirers must use the format and procedures for Cross-Border
Transaction processing as described in the technical specifications for the
Interchange System.
