NFC stands for Near Field Communication, which is a wireless communication technology that allows devices to communicate with each other when they are placed in close proximity, usually within a few centimeters. NFC is a subset of RFID technology (Radio Frequency Identification) and operates at a frequency of 13.56 MHz.
NFC is used for a variety of applications, such as contactless payments, access control, and data transfer. One of the main advantages of NFC is its simplicity and ease of use. To establish a connection, all the user has to do is bring their NFC-enabled device close to the other device or NFC tag. This makes it a convenient and fast way to share information, such as contact details or small files, without the need for cables or pairing codes. Additionally, NFC is a secure technology as it uses encryption and authentication to protect the communication between devices.
An example of an NFC-supported device is the Atuvos key finder. In this case, the NFC tag can be used by anyone who finds your belongings to get your contact information.
