who invented atm

The invention of the ATM is attributed to two Scottish engineers: John Shepherd-Barron and James Goodfellow.

• John Shepherd-Barron is widely credited with inventing and installing the world's first cash machine in London in 1967.
• The crucial technology for modern ATM security, the Personal Identification Number (PIN) system, was invented and patented separately by James Goodfellow in 1966. Goodfellow's PIN system is the foundation for the security used in almost all ATM transactions today.
