Near Field Communication (NFC) 
  • NFC is a short-range wireless connectivity technology that allows NFC-enabled devices to communicate with each other and transfer information quickly and easily with a single touch - whether to pay bills, exchange business cards, download coupons, or share a document.
  • NFC transmits data through electromagnetic radio fields, to enable communication between two devices. Both devices must contain NFC chips, as transactions take place within a very short distance. Hence statement 1 is correct.
    • NFC-enabled devices must be either physically touching or within a few centimetres from each other for data transfer to occur. Hence statement 2 is not correct.
  • In 2004, consumer electronics companies, Nokia, Philips and Sony together formed the NFC Forum, which outlined the architecture for NFC technology to create powerful new consumer-driven products.

Consider the following statements with reference to the Near Field Com...
Explanation:

Statement 1: It transmits data through electromagnetic radio fields.
Near Field Communication (NFC) technology uses electromagnetic radio fields to transmit data between two devices. NFC operates within a range of a few centimeters, making it a form of short-range wireless communication. This statement is correct.

Statement 2: Data transmission in Near Field Communication devices occurs only by physical touching.
Contrary to the statement, data transmission in NFC devices does not necessarily require physical touching. While NFC devices do need to be close to each other (within a few centimeters) for communication to occur, they do not have to physically touch. The close proximity ensures a secure connection while preventing interference from other devices. Therefore, this statement is incorrect.
Therefore, the correct answer is option A) 1 only.
