HOW DOES A AUTOMATED TELLER MACHINE WORK
how it works:
- Customer visits the ATM and inserts his card into the machine
- ATM reads the magnetic stripe to identify the user
- ATM prompts the user to enter his identification pin number
- If the user enters an incorrect pin, the transaction is cancelled and the card is returned
- If the user enters the correct pin, the machine shows him a menu of operations like withdrawal, deposit, balance inquiry etc.
- User chooses his option
- Machine connects to the bank database to check if the user has enough money in the account
- the machine dispenses cash that the user asked verification
- Machine updates users account with the withdrawal and updates
- Machine returns the card and a receipt to show the transaction occurred and details about it
- User takes his card and leaves the ATM with the money
- if an error occurs goes to bank and complains transaction aborted
