| 1. It is a contactless communication technology that uses electromagnetic radio fields. |
| 2. NFC is designed for use by devices which can be at a distance of even a metre from each other. |
| 3. NFC can use encryption when sending sensitive information. |
| Select the correct answer using the codes given below. |
A) 1 and 2
B) Only 3
C) 1 and 3
D) All of these
Correct Answer: C
Solution :
Exp. [c] Near Field Communication (NFC) is the set of protocols that enable electronic devices to establish radio communication with each other by touching the devices together or bringing them into proximity to a distance of typically 10 cm or less. There can be secure communications by applying encryption algorithm as it is done for Credit Card and if it fits the criteria for being considered a personal area network. Hence, option [c] is correct.
