Chip and Pin
A security method to reduce card fraud.
PIN stands for Personal Identity Number. Credit and Debit cards now include 'chip and PIN' technology. This means there is a microchip embedded within the card that can check if the PIN number you enter into the card reader is correct.
You can tell if a card is chip and pin by looking for a small rectangle of gold contacts on its surface. These are the electrical connections the card makes with the reader.
