NFC (Near Field Communication) technology is a wireless communication technology that allows devices to establish a connection by simply touching or bringing them close together. It is a short-range communication technology that operates on radio frequency identification (RFID) principles. NFC technology enables seamless and secure communication between devices, making it ideal for various applications.

How Does NFC Technology Work?
NFC technology operates on the principle of electromagnetic induction. It uses magnetic fields to enable communication between devices. NFC-enabled devices have a built-in NFC chip that contains an antenna. When two NFC-enabled devices are brought close together, their antennas generate electromagnetic fields.
One device acts as an initiator or active device, while the other device acts as a target or passive device. The initiator device generates a magnetic field that induces a current in the target device’s antenna. This current is then used to power the target device and establish communication between the two devices.
