What is Chip & PIN?
A. Chip and PIN is a secure card payment system that has been introduced to help prevent fraud. Most UK credit and debit transactions in shops and other retail outlets are authorised by keying in a unique PIN, rather than by signing a receipt. A PIN (Personal Identification Number) is a 4-digit code either assigned to, or chosen by a cardholder to help prove that they are the authorised owner of a card when making a chip and PIN based transaction. The same PIN is required when using a cash machine.
