PIN credit cards are cards that require a PIN to be entered as a way of authenticating a transaction. This is a new option that is being used as a substitute to signing names. The change was due to the need to provide a more convenient way for credit card users to carry out transactions.

Some of the credit card companies encourage card holders to ensure the PIN numbers remain confidential because they will be held liable in case of unauthorized transactions. PIN credit cards are now being offered by a majority of banks.
