With reference to ‘Near Field Communication (NFC) Technology’, which of the following statements is/are correct?

  1. 1.It is a contactless communication technology that uses electromagnetic radio fields.
  2. 2.NFC is designed for use by devices which can be at distance of even a metre from each other.
  3. 3.NFC can use encryption when sending sensitive information.

Select the correct answer using the code given below:

  1. A.1 and 2 only
  2. B.3 only
  3. C.1 and 3 only
  4. D.1, 2 and 3
▶ Answer & Explanation

Correct answer: C. 1 and 3 only

Near Field Communication (NFC) is a short-range wireless technology that enables two electronic devices to communicate when they are brought close to each other, typically within a few centimeters. It operates on the principle of electromagnetic induction, allowing for secure contactless transactions and data exchange. While NFC itself is designed for very close proximity, it can incorporate encryption protocols to secure the transmission of sensitive data.
