Over the past year, the payments industry has been abuzz with news of Visa’s plan to encourage adoption of EMV technology. While many in the payments industry have a clear understanding of what EMV is and how it might impact our business, for small merchants the term just adds on to the growing list of acronyms with which they must now be familiar. PCI DSS, PA DSS, QSA, SAQ, and now EMV. But what is EMV and what do small merchants need to know about it?
EMV itself is a standard begun by Europay, MasterCard International and Visa International. (Its current members are American Express, MasterCard, Visa, and JCB.) The three companies joined together to form EMVco, whose purpose is “to manage, maintain and enhance the EMV™ Integrated Circuit Card Specifications for Payment Systems.” In other words, the company was formed to promote the use of “smart cards.” A “smart card” is essentially a payment card with an embedded micro-processor, or chip. Because the chip can hold much more information than a magnetic stripe can, EMV enabled cards support multiple methods of authentication. This ostensibly makes the process more secure for both the merchant and the consumer. Since the chip can support dynamic and static authentication as well as online and offline authentication, the theory is that using EMV means that the risk of compromised card data being used fraudulently is significantly lower than with magnetic stripe data. In other words, even if the data is compromised, it is less likely that it can be used to perpetrate fraudulent transactions. As a result of its capabilities with respect to fraud prevention, Visa is strongly encouraging the US payments industry to move towards EMV. So, what does this transition mean for merchants?
1) The requirement to comply with PCI DSS will remain - Visa’s program states that if a merchant can verify that at least 75% of its transactions are EMV, then the requirement to validate compliance with the PCI DSS can be waived. It should be noted, though, that it is only the requirement to validate compliance that is being waived, not the obligation to comply itself. Another important caveat to this validation waiver is that only Visa has so far extended this offer. Merchants will still have to validate compliance as required with the other card brands.
2) EMV does not replace data security – The use of EMV cards does not inherently provide protections against the unauthorized access or disclosure of the data itself. Data thieves would still be able to compromise the data. However, the utility of the data is significantly lessened as a result of the layering of authentication mechanisms employed by EMV cards.
3) Acquirers/ Processors have to transition by 2013 – As of April 1, 2013 acquirers and processors must be able to support EMV transactions.
4) Liability Shift means Acquirers likely to encourage adoption – Visa has announced plans to implement an liability shift for fraudulent purchases. Currently, if a counterfiet purchase is made, it is largely left to the issuing bank (the bank that issued the card) to absorb. Under the new rules, which would take effect on October1, 2015 counterfeit purchases that occur at a merchant location that has not adopted the EMV technology may become the liability of the acquiring bank.
As the deadlines come closer, the card brands will release more detail that will help guide merchants on the path to EMV. Moving to EMV will be a challenge for an industry as fragmented as the US card processing ecosystem. Although there will be the inevitable growing pains, though, the technology will serve to benefit all of the stakeholders – from merchant to the consumer.
