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.
Statement 1 is correct. Near Field Communication (NFC) is indeed a contactless communication technology that relies on electromagnetic radio fields to transmit data between devices in close proximity. Statement 2 is incorrect. NFC operates over a very short range, typically requiring devices to be within a few centimetres of each other for successful communication. A meter is far too large a distance for NFC to function effectively. Statement 3 is correct. NFC can employ encryption to safeguard sensitive information during transmission. This is an important security feature for applications like contactless payments.
