Question

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

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 code given below. 

(a) 1 and 2 only (b) 3 Only (c) 1 and 3 only (d) 1, 2 and 3

Answer 1

(c) Near field communication utilizes electromagnetic radio fields while technologies such as Bluetooth and Wi-Fi focus on radio transmissions instead. Near Field Communication is an offshoot of Radio-Frequency Identification (RFID) with the exception that NFC is designed for use by devices within close proximity to each other. When a secure channel is established, the information is encrypted and only an authorized device can decode it. NFC users should ensure that the companies do their business with the use of secure channels.
