• The comparison, by the card issuer or the EMV chip on the card, of the value entered on a terminal’s PIN pad with the personal identification number (PIN) given to or selected by the cardholder upon card issuance; and

• The use of a consumer device CVM (CDCVM) that Mastercard approved as a valid CVM for transactions upon the successful completion of the certification and testing procedures set forth in section 3.11 of the Security Rules and Procedures.

In certain card-present environments, a merchant may complete the transaction without a CVM (“no CVM” as the CVM), such as in quick payment service (QPS) transactions, contactless transactions less than or equal to the CVM limit, and transactions at an unattended point-of-sale (POS) terminal identified as cardholder-activated terminal (CAT) Level 2 or Level 3.

Base II

VISA

BASE II Clearing System is the international electronic clearing system supporting transaction-based payment exchange between Visa clients.

Clearing is the process by which Visa collects data about a transaction from the source, validates the information and calculates fees, values the transaction (calculates the base value of the transaction as well as various fees and charges), and then delivers it to the destination. The destination uses this information to post the transaction to the cardholder’s account or reconcile a merchant’s settlement position.

BASE II Clearing System is one of Visa’s core processing functions, ensuring that merchants get paid and enabling clients to manage the accounts of cardholders. From a business standpoint, the clearing system is complex due to the number of regions it covers and the need to adapt the system to keep up with specialized arrangements by clients, unique banking regulations, legal agreements, and changing political landscapes.
