Detailed Explanations
Basic Operation
An ATM typically involves interaction with a card, such as a debit or credit card, which is inserted into the machine. The user then inputs a PIN (Personal Identification Number) to verify their identity. Transactions are conducted based on the user’s bank account information stored on the card’s magnetic stripe or chip.
Security Features
Modern ATMs incorporate various security measures such as encryption, anti-skimming devices, and biometric authentication to protect users from fraud.
