Chip and PIN
In the UK by 2005 most credit and debit card transactions will require the customer to input a 4 digit personal identification number (PIN) at point of sale rather than authorising by signing a paper receipt.
The process will be:
- The shop assistant will input the amount to be paid.
- The customer will hand their card to the assistant, or insert it themselves in the terminal.
- The customer will then check the amount on a visual display.
- The customer will input their PIN on a numeric keypad. This keypad will be on a flexible lead of sufficient length that it can be operated from a wheelchair.
- The terminal will print a receipt so that the customer has a record of the transaction.
In a restaurant, the system will be the same except that the waiter or waitress will have a portable terminal which he or she will hand to the customer for the PIN to be keyed in.
