Enhanced Security
Chip cards, when used in conjunction with a personal identification number (PIN), are a solution to counterfeit and lost and stolen card fraud. The chip prevents the card from being counterfeited and the PIN uniquely identifies the owner of the card and prevents it from being used by someone else if lost or stolen. When a chip card is used at the point of sale, the transaction message sent by the chip card to authorise the transaction does not contain any data that can be used to counterfeit a chip, or conduct an unauthorised chip transaction reusing the data from a previous transaction.
