Nailing PIN security

Four-digit chip and PIN numbers have been a feature of using bank debit cards in the UK for a year, with the system extending to credit cards in 2006. C&P is a good idea, despite what the detractors say because it is more secure than the system it replaced. Admittedly the system it replaced had almost no security at all other than asking people for signatures - and card-not-present transactions are not yet covered - but letís give it some credit for the reduction in fraud figures.

In at least one case we have learned of, it could have a small weakness - the envelope in which the PIN number is first sent to the customer. - Nailing PIN security
