NFC

Definition

NFC, or Near Field Communication, is a short-range wireless technology that enables data exchange between devices over a distance of typically 4 centimeters or less. This technology allows devices to communicate by simply being in close proximity, facilitating various applications such as mobile payments, ticketing, and data transfer. It connects seamlessly with the Internet of Things (IoT) and enhances connected logistics by enabling efficient communication between smart devices.
