Explanation:
Statement 1 is correct: Near Field Communication (NFC) is a contactless communication technology that uses electromagnetic radio fields to enable communication between devices when they are brought close together, typically within a few centimeters.
Statement 2 is incorrect: NFC is designed for short-range communication, typically within a few centimeters. It is not intended for use between devices that are at a distance of even a meter from each other.
Statement 3 is correct: NFC can use encryption when sending sensitive information to ensure the security and privacy of the data being transmitted.
