Question

Adam is paying his bill in a restaurant using a contactless debit card. Describe the computer processing involved in Electronic Funds Transfer (EFT) using contactless cards.

a) Encryption and Decryption
b) Data Storage and Retrieval
c) Signal Transmission and Reception
d) Mechanical Processing

Answer 1

Contactless debit cards use Electronic Funds Transfer (EFT) which involves encryption and decryption, signal transmission and reception, and data storage and retrieval.

Step-by-step explanation:

Contactless debit cards use Electronic Funds Transfer (EFT) to process transactions. The computer processing involved in EFT using contactless cards includes encryption and decryption to secure the transaction data, signal transmission and reception to communicate between the card and the payment terminal, and data storage and retrieval to store transaction information. Mechanical processing is not directly involved in EFT using contactless cards.
