Q: With reference to ‘Near Field Communication (NFC) Technology, which of the following statements is/are correct?
- It is a contactless communication technology that uses electromagnetic radio fields.
- NFC is designed for use by devices which can be at a distance of even a metre from each other.
- NFC can use encryption when sending sensitive information.
Select the correct answer using the code given below:
a) 1 and 2 only
b) 3 only
c) 1 and 3 only
d) 1, 2 and 3
The correct answer is 1 and 3 only.
Near Field Communication (NFC)
- It is a contactless communication technology based on an electromagnetic radio frequency (RF). Hence, Statement 1 is correct.
- It uses a base frequency of 13.56 MHz.
- It is perfectly designed to exchange data between two devices through a simple touch gesture.
- It is designed for an operating distance of a few centimetres. Hence, Statement 2 is incorrect.
- This makes it more difficult for attackers to record the communication as compared to other wireless technologies which have a working distance of several meters.
- It can use encryption when sending sensitive information. Hence, Statement 3 is correct.
