How ATM Transactions Work

  • ATM card is entered into the ATM – PIN is entered – Amount is entered for withdrawal
  • ATM dials the appropriate network (Star, Presto, Plus, Cirrus, etc.)
  • The appropriate network then contacts the customer’s financial institution to verify funds
  • If approved, the amount requested plus any surcharge is debited from the customer’s account
  • The transaction is processed through the Federal Reserve’s automated clearing house (ACH)
  • The surcharge and the amount withdrawn are electronically deposited in the owner of the ATM’s account
