Answer 1

Answer:

NFC

Explanation:

NFC (near-field communication) is the technology enabled in most smartphones nowadays. Also, it is widely used for contactless payments (paying with cards or phones) worldwide. Actually, the term NFC refers to the communication protocols between two devices that are 4 cm within of each other. The other technologies (Bluetooth) refer to a wider radius when communicating.
