HOW ATM WORKS
We all now know the ATM is an electro-mechanical device, with a switch that knows how much cash is available in an ATM and in what denomination. In a cash withdrawal transaction, once your PIN is verified and there is sufficient balance in your account, the switch sends an instruction to the ATM to dispense the amount requested. You would be receiving a mix of Rs2,000, Rs500, Rs100 and sometimes even Rs200 from ATMs
The currency notes inside the ATM are stacked in boxes called ‘cassettes’. Each cassette is loaded with one denomination. Most of the ATMs in the country have four such cassettes, while some of the older ATMs may have two cassettes.
Have you ever wondered how the ATMs know which denomination of notes to dispense and how many of each denomination? Most of the switches follow the principle of ‘last note to be dispensed in the lowest denomination available in the ATM’ at the time of withdrawal’. For example, if you want to withdraw Rs1,000 from an ATM and the ATM has Rs500 and Rs100 denomination available, it will dispense one note of Rs500 and five notes of Rs100. If instead of Rs500 and Rs100, it has Rs200 and Rs100, the ATM will dispense four notes of Rs.200 and two notes of Rs100.
James Goodfellow is the man who first patented automated cash machines that use pin numbers. Some say the inventor is John Shepherd-Barron. John D. White
