How does Chip & PIN work?
A chip embedded into your debit or credit cards is at the heart of Chip & PIN. Chip technology uses sophisticated processing to identify genuine cards and makes counterfeiting more complex and expensive. The technology checks the PIN you entered in the keypad against the PIN held on the chip. This is used to verify your identity instead of someone checking your signature on a receipt.
Many cards already carry a chip, identified by a gold or silver contact pad on the front left. However, all cards are being re-issued with chips that are PIN-enabled.
