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:
- 1 and 2 only
- 3 only
- 1 and 3 only
- 1, 2 and 3
Explanation
Statement 1 and 3 are correct and statement 2 is incorrect
- Near Field Communication (NFC) is a set of short-range wireless technologies, typically requiring a distance of 4 cm or less to initiate a connection. It creates a magnetic field induction to enable communication between devices when they’re touched together or brought within a few centimetres of each other. It builds on and extends the work of existing ecosystems and standards around radio frequency ID tags (RFID).
- NFC can use encryption to secure the transmission of sensitive information, such as during contactless payments or secure data sharing.
