What is EMV Chip Card Technology?
"EMV® is a global standard for credit and debit payment cards based on chip card technology" taking its name from the card schemes Europay, MasterCard, and Visa - the original card schemes that developed it. The standard covers the processing of credit and debit card payments using a card that contains a microprocessor chip.
Chip and PIN Definition
These transactions are often referred to as "Chip and PIN" because PIN entry is required to verify the customer is the genuine cardholder. This is a simplification since the EMV specifications include other cardholder verification methods as well.
EMV vs. Magnetic Stripe Transactions
Unlike magnetic stripe transactions, where typically only the card's track 2 data containing the card number and expiry date is processed, every chip card transaction contain dozens of pieces of information to be exchanged between the card, the terminal and the acquiring bank or processors host.
This requires the terminal to perform many stages of complex processing, including cryptographic authentication, to successfully complete a transaction. This means that adding support for EMV to existing payment applications can be a daunting task. For more information on the main processing steps required in an EMV transaction, please review this diagram showing a typical EMV Transaction Flow.

EMV in Numbers
EMVCo published its latest EMV deployment figures in May 2012. 45 per cent of all payment cards and 76 per cent of payment terminals used globally are based on EMV technology. There are over 1.5 billion EMV payment cards in circulation (up by 25% since 2011) and 21.9 million EMV terminals (up by 18% since 2011).
Before an EMV capable solution can be deployed, there are many EMVCo mandated tests that need to be passed to validate that an EMV implementation conforms to the EMV standard. As the EMV specificationsevolve and are regularly updated this can become a major job in itself - another reason why many businesses who require an EMV "Chip & PIN" or "Chip & Signature" solution opt to license a purpose built off the shelf EMV Software Kernel rather than develop their own in house.
To understand more about some of the terminology used in EMV we've compiled a useful Glossary of Terms.
EMVCo is jointly owned by American Express, JCB, MasterCard and Visa. It manages, maintains and enhances the EMV Specifications to ensure global interoperability of chip cards with acceptance devices such as point of sale terminals and ATMs.
All our EMV Kernels are EMVCo compliant and we are proud to have achieved have a 100% first time pass rate.
