Card Security Code or CVV2 (Card Verification Value)
An anti-fraud device used by some card issuers as a means of protection against invented or altered magnetic stripe content.

CCS Cardholder Currency Selection

The term used where a card issuer can charge part or all of the value of a transaction back to the merchant via their acquirer.

Chip and PIN
Chip and PIN is a programme aimed at reducing fraud for those transactions where the cardholder and card are present at the time of the transaction.

The Chip (silver or gold coloured square on the front left side of the card) is embedded into a card to provide highly secure memory and processing capabi­liti­es. In addition to holding the same personal data as the magnetic stripe, the chip provides additional security features to safeguard against co­un­ter­fe­iting.

The PIN is a four-digit number that the cardholder will enter into the PIN pad instead of signing a card receipt. From January 2005, liability for counterfeit card transactions and lost and stolen card fraud, will pass to the party that is not chip & PIN compliant. Where all parties are compliant, then counterfeit transactions should reduce sig­ni­fic­an­tly and there will be no recourse by the cardholder saying they did not authorise the transaction.

CNP- Cardholder Not Present
