(PIN) entered on a keypad. The short-range beta emission from carbon-14 could be easily detected, and he determined that the radiation hazard was acceptable as "you would have to eat 136,000 such cheques for it to have any effect on you". Initially, a PIN length of six digits was proposed; Shepherd-Barron tested this system on his wife, Caroline, but found that the longest string of numbers that she could remember was four. As a result, four-digit PINs were chosen and as ATMs expanded across the globe, this became the world standard. Withdrawals from the first ''Barclaycash'' machines were limited to a maximum of £10, "quite enough for a wild weekend" according to Shepherd-Barron. Shepherd-Barron received the OBE in the 2005 New Year's Honours list for services to banking as "inventor of the automatic cash dispenser". Various rival cash dispenser systems quickly began to emerge. Another Scottish inventor,

to work on a new cash machine. Together with Anthony Davies, he developed a new system whereby the user's PIN could be stored on a reusable bank card, rather than on single-use cheques. The system was patented as GB1197183 and US3905461 and was cited by subsequent patents as "prior art device". Goodfellow's PIN system resembled modern ATMs more than Shepherd-Barron's machine. However, Shepherd-Barron's machine was the first to be installed, if only for a few days.
