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.

Let's analyze the statements regarding 'Near Field Communication (NFC) Technology':

1. It is a contactless communication technology that uses electromagnetic radio fields: This statement is correct. NFC operates on the principles of radio-frequency identification (RFID) and uses electromagnetic induction to enable communication between devices that are in close proximity.

2. 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 specifically designed for very short-range communication, typically limited to a few centimeters (usually 4 cm or less). This close proximity requirement enhances security and prevents accidental communication.

3. NFC can use encryption when sending sensitive information: This statement is correct. While NFC itself does not inherently provide strong encryption, it can be used in conjunction with security protocols and encryption methods (e.g., within payment systems or secure access applications) to protect sensitive data during transmission. The security of NFC transactions often relies on higher-layer protocols and software implementations.

Therefore, statements 1 and 3 are correct.
