Orla O'Neill =PIN Pads: =

This is a device that allows you to put your debit/credit card in and enter your Pin. After you have entered your PIN, money is drawn from your account and it pays for the items etc. you are purchasing. They are usually used in a shop where the cash registar is responsible for taking the sale amount.
 * __What is it?__**

When a customer wants to pay for the items he/she is buying using a PIN Pad, their card is placed into the PIN Pad which accesses the chip reader on the card. Once the card has been accepted, the customer types in their four-digit PIN, which is then checked to see if it's right on the card. If it is, then money is drawn from your account.

=**Chip Readers: **= Credit and Debit cards now include ''Chip and Pin', which include electrical connections the card makes with the reader. When the card is swiped at the till, it picks up informations from a microchip embedded within the card that can check if the PIN number you enter is correct. You can tell if a card is 'Chip and Pin' by looking for a small rectangle of gold contacts on its surface. (This is what the chip reader is)
