Credit and debit cards contain an embedded microchip and are authenticated automatically using a personal identification number (PIN).
This system has provided the possibility of integrated payment systems in many easy to access spaces, including retail outlets, bookmakers, restaurants, public houses and many other businesses that require payment of goods and services.

This has most notably been integrated into supermarkets where the customer can now use the checkout to withdraw cash, when paying for their goods on departure. This amount is regulated by a minimum and maximum withdrawal limitation, but has proven to be a beneficial value added service.
