Visa (NYSE:V) today modified and clarified existing debit network routing rules to help merchants and acquirers better understand implementation options related to the adoption of EMV chip technology in the U.S. The modifications and clarifications follow new guidance recently issued from the Federal Reserve and address a Federal Trade Commission inquiry.
With Visa chip cards, debit routing and processing are enabled by two payment application identifiers (AIDs) on the chip – the U.S. Common Debit AID or the Visa Debit AID. The Common Debit AID can support any of the more than one dozen domestic debit networks that issuers can choose to offer in addition to Visa Debit. This provides merchants with the ability to select the network over which a debit transaction is processed or routed.
