Near Field Communication (NFC) refers to a wireless communication technology facilitating data exchange over short distances. Primarily utilized for contactless transactions like mobile payments and data sharing among devices such as smartphones and smartwatches, NFC operates by initiating a connection between two devices through radio waves when brought within close proximity, typically a few centimeters. Once established, data transfer between devices commences. Recognized for its security, NFC relies on short-range connections necessitating physical proximity between devices.

Rapidly gaining traction, NFC technology enjoys broad compatibility across a spectrum of devices, spanning smartphones, tablets, and wearable gadgets. Its utility extends to various applications, encompassing contactless payments, access control, and seamless data exchange among devices.
