History of the atm

History of the ATM:

NCR produced the first ATM in Dundee, Scotland. This ATM was installed by Barclays Bank in north London on June 27, 1967 in Enfield Town. John Shepherd-Barron is credited for the invention, although in the 1930s, George Simjian registered patents in New York, USA, while Don Wetzel and two other engineers from Docutel registered a patent on June 4, 1973.

The first cards worked on various principles including radiation and low-coercivity magnetism, which made fraud more difficult. The modern ATM card we use today was first tested in the Christchurch region of New Zealand before they were offered as a banking service elsewhere.

ATM customers are identified by a plastic card containing a magnetic stripe. The stripe is encoded the customer's account number, which is accessed by properly entering a numeric pass code referred to as a personal identification number (PIN). If the PIN number has been entered incorrectly repeatedly, several ATM machines will keep the card as a security precaution.
