They say that John Shepherd-Barron who worked at the commission of De La Rue company that still produces paper for printing money was very stressed out by the impossibility to obtain cash at night or on Sundays. Therefore, he tried and invented a cash machine that was installed in the Barclays Bank in the northern part of London. The machine was quite primitive: it could neither connect with the bank nor check one’s account. However, it did give money: the same amount to everyone who acquired a special check beforehand. Those forward-thinking people put the check into the machine and received money, carefully packed in an envelope. Soon this idyllic picture spread beyond England: inventors and cash machines started appearing a dime a dozen, and the computer that started spreading quite opportunely married the cash machine to the bank account, using the banking card as a wedding ring. The screens of 1.5 million cash machines look at the streets of all the cities and towns of the world from vertical surfaces. They learned to take money from the clients (and in an instant, to give them to another client), to read barcodes on receipts and to do lots of other things handy for busy people. In the course of technical progress, cash machines developed various details like rails for rollers or mechanisms for washing money. There are attempts of plundering them every now and then, but bank owners and technical experts manage to outsmart the cunning hackers, inventing tricky lock codes. And the card is being improved continuously, with a tendency towards biometric technologies that are impossible to fake.
