Today, if an in-store transaction is conducted using a counterfeit, stolen or otherwise compromised card, consumer losses from that transaction fall back on the payment processor or issuing bank, depending on the card's terms and conditions.
After an Oct. 1, 2015, deadline created by major U.S. credit card issuers MasterCard, Visa, Discover and American Express, the liability for card-present fraud will shift to whichever party is the least EMV-compliant in a fraudulent transaction.
Consider the example of a financial institution that issues a chip card used at a merchant that has not changed its system to accept EMV card technology. This allows a counterfeit card to be successfully used. The cost of fraud will be on the merchant.
Any merchants not EMV-ready by October 2015 could face much higher costs in the event of fraudulant transactions.
