Bank card

[1] It will have a magnetic strip on the back enabling various machines to read and access information.

[2] Depending on the issuing bank and the preferences of the client, this may allow the card to be used as an ATM card, enabling transactions at automated teller machines; or as a debit card, linked to the client's bank account and able to be used for making purchases at the point of sale with a bank card using a payment terminal.

The first bank cards were ATM cards issued by Barclays in London, in 1967, and by Chemical Bank in Long Island, New York, in 1969.

[3] In 1972, Lloyds Bank issued the first bank card to feature a personal identification number (PIN) for security along with the information-encoding magnetic strip.

[4] Historically, bank cards have also served the purpose of a cheque guarantee card, a now almost defunct system to guarantee cheques at points of sale.
