Explanation:

"It is a contactless communication technology that uses electromagnetic radio fields."

This statement is correct. NFC is a form of contactless communication that allows data to be exchanged between devices through electromagnetic radio fields. It's used in various applications like contactless payments, data transfer, and access control.

"NFC is designed for use by devices which can be at a distance of even a metre from each other."

This statement is incorrect. NFC is designed for short-range communication, typically requiring a distance of about 4 cm or less. It is not intended for long-range communication like other technologies such as Bluetooth or Wi-Fi.

"NFC can use encryption when sending sensitive information."

This statement is correct. NFC can be secured with encryption, which is especially important for applications involving sensitive data, such as contactless payments.

Therefore, two of the statements are correct (statements 1 and 3).
