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.

1. Near Field Communication (NFC) Technology is a short-range wireless connectivity standard that uses magnetic field induction to enable communication between devices when they're touched together or brought within a few centimeters of each other. It operates using electromagnetic radio fields, making it a form of contactless communication. Hence, statement 1 is correct. 2. NFC has a very short operational range, typically 4 cm or less. It is explicitly designed for close proximity interactions, not for distances approaching a metre. Hence, statement 2 is incorrect. 3. While the base NFC standard itself might not include mandatory encryption for all communication, secure applications built on top of NFC (like payment systems or secure access) can and do implement encryption and other security measures to protect sensitive information during transmission. Hence, statement 3 is correct. 4. Therefore, statements 1 and 3 are correct.
