We’re now nearly midway through 2015, and payment security still remains a topic that stirs up great concern and confusion. While there is seemingly unanimous agreement on the need for heightened security, there’s uncertainty about those who are tasked with actually implementing it. Let’s dig deeper into EMV, P2PE and tokenization. How each will play a part in the next generation of securing payments, and how without properly working together they might just fall short.
Europay, MasterCard, and Visa (EMV) – A powerful guard against credit card skimming. EMV also uses cryptography to create dynamic data for every transaction and relies on an integrated chip embedded into the card.
Downside: For Independent Software Vendor (ISVs), the biggest downside of EMV is the complexity of creating an EMV solution. ISVs interested in certifying PINpads with a few processors face up to 22 months of costly work, and because there are a large number of pending certifications, processors will be backed up over the next few years.
It’s not impossible for an ISV to build EMV solutions in-house, but it’s difficult and unnecessary when there are plug-and-play EMV solutions available. These solutions include pre-packaged and pre-certified APIs that remove most of the need for research, the complexity and the burden of time and cost.
Point to Point Encryption (P2PE) – Secures devices, apps and processes using encrypted data with cryptographic keys only known to the payment company or gateway from the earliest point of the transaction, from tech-savvy criminals, jumping at their chance to intercept POS systems and scrape the memory from Windows machines.
How does a key get into card reader? Through an algorithm called derived unique key per transaction (DUKPT), or “duck putt.” DUKPT generates a base key that’s shared with device manufacturers securely, where output cardholder data is rendered differently each time a card is swiped, making it impossible to reverse engineer the card data. P2PE not only benefits the cardholders, but also the ISVs and merchants. PA-DSS certification was designed to address the problems created with cardholder data which is not encrypted.
Downside: P2PE isn’t cheap if an organization wants to do it in-house. The secure cryptographic device needed to manage the keys, Hardware Security Module (HSM), can cost $30-40,000 but when it’s built out, that total cost can jump to $100,000.
TOKENIZATION – The best way to protect cardholder data when it’s stored is using tokenization, a process which the PCI Security Standards Council describes as one where the primary account number is replaced with a surrogate value a token. For merchants dealing with recurring billing, future payments, loyalty programs and more, tokenization is critical.
Downside: Tokenization doesn’t prevent malware that’s remotely installed on POS devices. It’s possible, as seen with recent retail card breaches, for data to be stolen before it is tokenized. That’s why it’s essential to group tokenization together with P2PE and EMV to offer optimal security.

The U.S. government will replace roughly 9 million government-issued payment cards with EMV chip-and-PIN versions early next year in a push to increase awareness and use of the more secure cards. Between 5 and 6 million prepaid debit cards used for issuing government payments, including Social Security and veterans benefits, will be reissued in January 2015. Another 3 million cards issued to federal government employees will also be replaced with EMV versions through the General Services Administration’s SmartPay program.
All the cards will be set up for Chip and PIN security as a U.S. government standard under the upgrade program, rather than the Chip and Signature approach required by Visa and MasterCard for most U.S. retailers starting late next year. However, there was no indication that the new cards will actually have the less secure magnetic data stripe removed.
Finding the right answers with the latest technologies to stop these cyber thieves and taking proactive and positive steps by adopting PIN and chip technology for government-issued debit and credit cards shows the importance of protecting financial transactions. While EMV is important, it’s not a total solution to the issue of data security.
POS devices at all federal agencies that accept retail payments will also be converted to accept EMV cards on a schedule set by the U.S. Treasury Dept. No timetable was given for the federal POS conversion.
The rollouts at four of the six largest U.S. retail chains will give a boost to EMV, which despite an October 2015 deadline has seen slow uptake among retailers. Under a mandate by Visa and MasterCard, retailers who experience credit or debit card fraud after next October but haven’t upgraded their POS equipment to accept EMV cards will be liable for the loss. If the bank that issued the card hasn’t upgraded it to EMV, the bank will take the loss.
But despite that October deadline, fewer than half of retailers’ POS terminals are expected to be able to accept EMV cards by the end of 2015, and barely half of U.S. payment cards will have been upgraded by then, according to the Payments Security Task Force, a banking industry group tracking EMV uptake.
The 9 million federally issued cards are a tiny fraction of the 1 billion credit and debit cards in use in the U.S., so the overall impact of accelerated EMV conversion is likely to be small. However, the Buy Secure initiative also explicitly includes a consumer-education component. Visa said it will spend $20 million in a public service campaign, and American Express said it will launch a $10 million program to help small merchants upgrade their POS terminals.
Small merchants are less likely to know about EMV than large retail chains, which have been making implementation plans for years.
