A bank counter that did not have to close
Shepherd-Barron’s vending-machine comparison was more than a clever analogy. A shop could make a product available after its staff went home; a bank, by contrast, traditionally tied cash access to a staffed branch and its opening hours. A machine offered a way to separate one basic service—getting cash—from the counter where customers also received help and completed more complicated transactions.
That shift mattered to both sides. Customers could withdraw money outside business hours, while banks could extend access without keeping a teller window open at every hour. It did not eliminate the cost of cash: machines had to be installed, supplied with money, and protected. Instead, it moved part of the service from a person at a counter to equipment operating on the bank’s behalf.
From the vending idea to a secure withdrawal
The first generation was not simply a modern card reader in a metal cabinet. Shepherd-Barron’s early system, introduced at a Barclays branch in London in 1967, used a coded, single-use paper voucher. The customer presented the voucher and entered a personal identification number, or PIN—a secret code used to check that the person requesting cash was authorized. The machine then dispensed a set amount.
Later systems made the process more flexible by using bank cards and electronic checks of the customer’s account. The underlying exchange remained recognizable: prove authorization, confirm that money can be withdrawn, and release cash without a teller handling the transaction.
The lasting change was not merely a new way to withdraw. It made access to money less dependent on the bank’s timetable—and turned the bank’s opening hours from a hard limit into a choice about when to visit.
