Under the old magnetic strip system, a customer would have to hand their card to the assistant for each payment. In certain environments such as restaurants, for example, this often meant that the card would be taken away from the customer to the card machine. This is no longer the case with the introduction of Chip and PIN as “wireless”, “mobile” or “portable” Chip & PIN credit or debit card terminals have been introduced that can be brought to the customer’s table. This stops card numbers being copied when their paying for goods reducing the risk of fraud.
