How Your ATM Counts Cash in Milliseconds
Episode 4311
Published 4 weeks, 1 day ago
Description
When you shove crumpled banknotes into an ATM, a robotic vault with more sensors than a lab instrument validates each one at eight notes per second. This episode traces the origin story from 1967's radioactive-cheque machine to today's sensor-fusion marvels — optical, magnetic, and ultrasonic checks all happening in parallel — and reveals how predictive maintenance keeps error rates below one in a hundred thousand transactions.
