ATM card

In some countries: An ATM card (also known as a bank card, client card, key card or cash card) is an ISO 7810 card issued by a bank, credit union or building society.
Its primary uses are:
at an ATM for deposits, withdrawals, account information, and other types of transactions, often through interbank networks
at a branch, as identification for in-person transactions

at merchants, for EFTPOS (point of sale) purchases
Unlike a debit card, an ATM card can only be used for transactions in person (and not by telephone, fax or internet), as it requires authentication through a personal identification number or PIN. In other words, it cannot be used at merchants that only accept credit cards.
In countries that don't have distinct debit cards (pure ATM cards without debit card function), such as Canada, an ATM card is also known as a "debit card".

In other countries: A cash machine card is used exclusively with cash machines. For making purchases, a debit or credit card is used instead. A physical card may sometimes be a combined cash machine card, debit card and credit card.
