RFID is a network protocol used in credit cards, smartphones, and tickets to facilitate close-range communication.

• A. True
• B. False
• C. Not a Protocol
• D. Only For Access Control

Answer: (B)

RFID is a technology that uses radio waves to identify objects with tags. It isn’t a single network protocol; it’s a family of standards and communication methods. In practice, credit cards and smartphones often use near-field communication (NFC) for close-range, secure transactions, and NFC is a specific protocol built on RFID principles. Because RFID covers a broader set of standards and can operate at various ranges (not just close range), the statement that RFID is a network protocol used specifically for close-range communication in those devices isn’t accurate.
