What makes up an ATM?

• Mainboard - This part controls the processing of the ATM. This houses the CPU, memory, and provides connection to all the other ATM parts.
• Card Reader - This part reads account information that is stored on an EMV chip or magnetic strip. Most card readers and cards today are EMV-enabled. The EMV acronym stands for Europay, MasterCard, Visa. It is the global standard for chip-based debit and credit card transactions. The EMV chip creates a unique transaction code for that particular transaction.

• Cash dispenser - This part moves cash from the cassette to the cash tray.
• Printer - This part prints the receipt for the customer.
• Power Supply - This part connects the rest of the ATM to external power.
