What technology is primarily used to establish a connection between peripheral devices and mobile devices over short distances?

The technology that is primarily used to establish a connection between peripheral devices and mobile devices over short distances is Near-field Communication (NFC). NFC enables communication between devices that are very close to each other, typically within a few centimeters. This technology is widely used for activities such as mobile payments, data sharing, and connecting devices quickly without the need for a complex setup process.

NFC operates by creating a magnetic field that enables two devices equipped with NFC capability to exchange data. This makes it extremely efficient for tasks that require a secure, short-range connection, such as tapping a phone to a payment terminal or pairing with accessories.

While Bluetooth and Infrared Technology also facilitate short-range communication, NFC is specifically designed for very quick, easy interactions between devices in close proximity. Wi-Fi Direct, on the other hand, typically operates over larger distances compared to NFC, allowing devices to connect directly without the need for a traditional wireless router but wouldn’t be classified as a short-distance technology in the same context as NFC.
