Question

. Consider a scenario where branches of a Bank are situated in multiple cities and when a user enters his ATM card in an ATM machine then Which system call will be used during ATM card verification?

Answer 1

The first ATM appeared at a branch of Barclay's Bank in London in 1967, although there are reports of a cash dispenser in use in Japan in the mid-1960s. The interbank communications networks that allowed a consumer to use one bank's card at another bank's ATM came later, in the 1970s.

Within a few years, ATMs had spread around the globe, securing a presence in every major country. They now can be found even in tiny island nations such as Kiribati and the Federated States of Micronesia.
