The outlook is uncertain for U.S. migration to “chip and PIN” POS payment-card technology, reports Vizant Technologies, a CBA partner that specializes in protecting companies that use payment-card processing. Controversy and confusion abounds regarding the Europay, MasterCard, and Visa (EMV) standard for credit and debit payment cards based on chip card technology. The POS liability shift was scheduled Oct. 15, but Visa, MasterCard, and the debit networks are debating the Application Identifier (AID) issue, which involves varying codes on payment card memory chips that must be standardized. The identifier issue will play a major role in debit card issuance and POS terminal decisions.  EMV technology requires POS systems to read a card and a customer must input a matching personal identification number (PIN) to complete the transaction.
