Answer:Near-field communication
Explanation:
Near Field Communication is an umbrella term that applies to location-aware technologies that allow devices to communicate securely with each other over short distances. Near-field communication is a short-range wirelessconnectivity standard that uses magnetic field induction to enable communication between devices when they're touched together, or brought within a few centimeters to each other.It also specifies a way for the devices to establish a peer-to-peer network to exchange data. After the peer to peer network has been configured, another wireless communication technology, such as Bluetooth or Wi-Fi, can be used for longer-range communication or for transferring larger amounts of data.
The tactile system is actually made up of two distinct skin senses;
protective and the discriminative system. The function of the protective system

are touching, where on our bodies is touching us and what are touching us. The receptors
for his system are the hands, fingers, soles of feet and mouth and tongue.
