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 codes given below.
✓ Correct answer: c) 1 and 3 only
ExplanationNear Field Communication (NFC) is a short-range wireless technology that allows devices to communicate by tapping or bringing them close together.NFC is used in various applications, including contactless payments, data exchange, and access control.Statement 1 is correct: NFC is a short-range wireless communication technology that enables devices to exchange data over distances typically up to 4 centimeters.It operates by generating electromagnetic fields through inductive coupling at a frequency of 13.56 MHz, which facilitates the transfer of information between devices.This contactless technology is widely used in mobile payments, access control, and data exchange.Statement 2 is incorrect: NFC technology is designed for an operation distance of a few centimeters(not meter).This makes it more difficult for attackers to record the communication between an NFC Forum Device and an NFC Forum Tag compared to other wireless technologies which have a working distance of several meters.Statement 3 is correct: NFC technology incorporates encryption methods to secure data transmission,
