P
Paper Merchant		A merchant without electronic capability who accepts card transactions using paper vouchers.
Personalisation		Adding user specific application software and individual personal details to a card.
PIN		Personal Identification Number. A set of numeric characters, usually a four-digit sequence, used by the cardholder to verify identity at the point-of-sale or a customer activated terminal, such as an ATM. The number is generated by the card issuer using a secure computerised process when the card is first issued and may be changed by the cardholder thereafter (see PIN change).
PIN Change		The ability of a cardholder to select a different PIN to that generated by the card issuer by whatever means.
PIN Lock		The process by which a card is blocked from further use following a specified number of consecutive incorrect or unsuccessful PIN entries, typically three (see also PIN unlock).
PIN pad		The numeric pad into which a cardholder keys their PIN to authorise a transaction. PIN pads may be fixed or portable. PIN pads are also referred to as PIN Entry Devices (PED).
PIN Services		The services (PIN change and PIN unlock) provided to cardholders to enable them to manage their PINs. PIN change enables cardholders to change the PIN to something more memorable and offers reassurance where there is concern that their PIN may have been compromised. PIN unlock ensures that cardholders can quickly and conveniently re-establish access to card payments.
PIN Unlock		A process to unlock the PIN on the card. This will normally only be possible at an ATM.
Point-Of-Sale (PoS)		(or Point of Service) Location where a customer makes a purchase.
PMO		Programme Management Organisation responsible for co-ordinating the chip and PIN project on behalf of retailers, acquirers and issuers.
PoS Terminal		An electronic device used to accept and process card payments at point-of-sale.
PoS Transaction		A transaction that takes place at point-of-sale.
Pre-Payment Card		See Electronic Purse.
Public Trial		Used to describe the Chip and PIN Programme activity planned for 2003 in Northampton. The focus will be on trialing the operational, implementation and communication activities associated with the rollout of chip and PIN. It constitutes the first phase of the chip and PIN rollout.
