While EMV represents a significant improvement in the way credit/debit card fraud is detected and prevented, some have confused EMV’s capabilities with the concepts of data security and PCI compliance.
Does EMV override PCI?
The answer is NO, EMV technology does not satisfy any PCI requirements, nor does it reduce PCI scope.
- EMV is counterfeit card fraud protection – it makes it more difficult to make use of stolen card data.
- EMV is not encryption – EMV does not encrypt the Primary Account Number (PAN) and therefore the card data must still be protected according to PCI guidelines.
- EMV only works for card present transactions.
If your business accepts credit or debit cards in a physical store or other face-to-face setting, you will need to implement the EMV technology and PCI standards. If you upgrade your terminals for EMV, consider adding point-to-point encryption (P2PE) capabilities to reduce PCI scope and protect data end to end. In addition, using tokens after authorization can prevent the card data from being used, should it be stolen.

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.

November 7, 2013 – Payment Card Industry (PCI) Council’s recent acceptance of the world’s first Point-To-Point Encryption-validated solution is great news for both acquirers and merchants, and will aid in reducing merchant scope and increasing business security worldwide. If your P2PE know-how is a little spotty, here are the basics.
What is P2PE?
Point-To-Point Encryption (P2PE) is the combination of hardware and processes that encrypts customer credit/debit card data from the point of interaction until it reaches a merchant solution provider’s environment for processing. Because card data is immediately encrypted as the card is swiped (or dipped), it prevents clear-text information from residing on the payment environment. Encrypted card data is then transferred to, decrypted by, and processed through the solution provider processor who is the sole holder of the decryption key.
In a POS environment, merchants often store decryption keys on their backend servers. Bad idea. If a cybercriminal hacks into that environment, they not only have access to the encrypted card numbers, but the decryption key as well. Hacker jackpot. Many question the difference between P2PE and typical point of sale (POS) encryption.
The reason P2PE is arguably the most secure way to process is because merchants don’t have access to decryption keys. If a hacker breaches a merchant using a validated P2PE solution, he/she will only recover a long string of useless encrypted card numbers with no way to decode them.
Why use P2PE?
Basically, P2PE increases data security and has the ability to make a merchant’s job of reaching PCI compliance easier. The main point of using a P2PE-valiated solution is to significantly lessen the scope of security efforts through PCI Data Security Standard (DSS) requirement and P2PE Self-Assessment Questionnaire (SAQ) reduction. Compared to the 80+ questions required of mainstream merchant SAQs, the P2PE-HW SAQ only requires merchants to answer 18 questions.
Are all P2PE solutions created equal?
Answer is no. Many P2PE solution vendors claim their solution reduces scope, but in order for a merchant to qualify, they must select only P2PE-validated solutions listed on the PCI Council’s website.
To get P2PE solutions and applications listed on the approved website, solution provider processors must go through a rigorous testing process performed by a qualified P2PE Qualified Security Assessor (QSA). P2PE QSAs help entities thorough the 210-page document of P2PE requirements, testing procedures, and controls required to keep cardholder data secure – a task which only a few companies in the world can do.
As of this post, the only P2PE hardware solution approved by the PCI Council is European Payment Services’ (EPS) Total Care P2PE solution, validated by P2PE QSA SecurityMetrics. A number of other P2PE solutions are currently undergoing the review process and will be added to the list once approved.
