NFC (Near Field Communication) tags are small, wireless devices that store and transmit data when brought close to an NFC-enabled device, such as a smartphone. These tags use RFID (Radio Frequency Identification) technology to facilitate contactless communication within a short range (typically less than 4 cm).

NFC tags can be programmed to perform various tasks, such as:

• Opening a website or app

• Sharing contact details

• Connecting to Wi-Fi networks

• Making mobile payments

• Automating smart home functions
