How an ATM transaction really works (and how testing fits in)

  1. 1. The basics. Follow the money. Receipt Printer: Upon request, a paper receipt of the transaction is distributed.. Keypad: This allows customers to communicate with the ATM: input PIN code, select amount of cash, transaction type,… Card Reader: Reads the information that is stored on a debit or credit card. The data retrieved is sent to the payment host or payment processor, which decrypts the information and retrieves the customer’s account information. QR code displayed on screen: Enables users to withdraw cash by scanning the QR Code on the ATM screen (with a mobile device). Cash Dispenser: The device that distributes cash from the ATM’s vault. Mobile device: Withdraw cash using ApplePay, SamsungPay, AndroidPay,…or scan the displayed QR code via a bank’s app. Display: Guides users through the different steps of an ATM transaction. It can also be used to interact with the ATM using the buttons or touch screen. EMV debit, credit or prepaid card: After inserting the chip card in the card reader, the user just enters a four digit Personal Identification Number (PIN). This number must correspond to the information that is stored on the chip. Deposit Slot: Allows users to deposit cash or checks. Confirming quality: how ATM testing works.
