@interestingentrepreneurs: June 27, 1967: The invention of the automated teller machine that transformed banking history. A transparent look into how cash is dispensed from an automated teller machine. This educational cutaway model reveals the complex internal mechanics required to complete a single withdrawal. Once a card is inserted, internal electronic contacts read the chip data to verify authentication. Down in the lower safe area, mechanical pickers, gears, and rubber rollers select individual bills from specialized cash cassettes. The system carefully separates each note to ensure proper counting before transporting the physical cash upward through high speed belts. From the invention of early cash dispensers to modern automated systems handling billions in USD every day, this mechanical process revolutionized financial history by making cash accessible around the clock.
