Question

BlackTom AI · Accepted Answer

The question asks why NFC is a better choice than RFID for storing a bus ticket and student ID on a phone for quick access.
Option a: 'RFID chips are always more secure than NFC' is not correct. Security depends on implementation and standards; NFC can use secure elements and encryption, but it's not accurate to claim RFID is always more secure.
Option b: 'RFID can only be used with laptops' is incorrect. RFID technology supports many use cases, including access cards, inventory, and devices beyond laptops, so this statement is false.
Option c: 'NFC requires no power source to work' is misleading. While NFC tags can be passive, a phone using NFC still relies on its own power and the reader’s power as part of the communication; the statement oversimplifies power needs and is not accurate as a general rule.
Option d: 'NFC is designed for close-range and device-to-device communication' is correct. NFC is explicitly optimized for near-field communication between devices (phone to reader or another device) within a short distance, which fits the use case of tapping a phone to access a ticket or ID efficiently.
