With reference to Near Field Communication (NFC) Technology, which of ...
Explanation:
NFC technology is a form of contactless communication that uses electromagnetic radio fields to enable communication between devices when they are brought within a few centimeters of each other. Here are the correct statements explained in detail:
1. It is a contactless communication technology that uses electromagnetic radio fields:
NFC technology allows for communication between devices without the need for physical contact. It operates on the principle of electromagnetic radio fields, which enable data transfer between devices in close proximity.
2. NFC is designed for use by devices which can be at a distance of even a metre from each other:
This statement is incorrect. NFC technology is designed for short-range communication, typically up to a distance of a few centimeters. Devices need to be brought very close to each other for NFC communication to occur.
3. NFC can use encryption when sending sensitive information:
NFC technology can indeed use encryption to secure the transmission of sensitive information between devices. This ensures that data transferred via NFC is protected from unauthorized access or interception.
In conclusion, the correct statements about NFC technology are that it is a contactless communication technology that uses electromagnetic radio fields and that it can use encryption when sending sensitive information.
