{'near field communication': [0, 0, 0, 1], 'nfc': [0, 0, 0, 1], 'contactless communication technology': [0, 0, 0, 1], 'electromagnetic radio fields': [0, 0, 0, 1], 'encryption': [0, 0, 0, 1], 'distance': [0, 3, 3, 3], 'devices': [0, 1, 0, 7], 'sensitive information': [0, 0, 0, 1], 'technology': [1, 5, 15, 27]}

The correct answer is 1 and 3 only.

1. It is correct that Near Field Communication (NFC) is a contactless communication technology that uses electromagnetic radio fields. NFC enables devices to establish communication by bringing them close to each other.

2. The statement is incorrect. NFC is designed for short-range communication, typically within a few centimeters. It is not intended for use at a distance of a meter or more.

3. It is correct that NFC can use encryption when sending sensitive information. Encryption ensures the security and privacy of data transmitted over NFC.

Therefore, the correct answer is 1 and 3 only.
