NFC Tags Applications

What is an NFC Tag?

NFC (Near Field Communication) tags are small, wireless communication devices that use radio-frequency identification (RFID) technology to exchange data over short distances, typically within a range of 4 centimeters. These tags consist of three main components: an antenna, a microchip, and a substrate. The antenna facilitates communication, the microchip stores data, and the substrate holds the components together. NFC tags are passive devices, meaning they do not require a power source; instead, they draw energy from the NFC-enabled device interacting with them.

NFC tags are widely used in various applications, including contactless payments, access control, inventory management, and marketing. They are compatible with most modern smartphones and other NFC-enabled devices, making them highly versatile and accessible.

Key Features of NFC Tags
