NFC (Near Field Communication) technology is a set of communication protocols that enable two electronic devices, one of which is usually a portable device such as a smartphone, to establish communication by bringing them within 4 cm of each other. NFC is based on RFID (Radio Frequency Identification) technology and operates at 13.56 MHz frequency. It allows for simple and safe two-way interactions between devices, making it a popular choice for contactless payments, data exchange, and device pairing.

NFC technology was first introduced in 2002 by Sony and Philips. It has since been adopted by various industries, including finance, retail, and transportation. In the finance sector, NFC is widely used for contactless payments, allowing consumers to make purchases by simply tapping their smartphones or cards on a payment terminal. In retail, NFC enables features like mobile shopping, where customers can scan products using their smartphones to access information or make purchases. In transportation, NFC is used for contactless ticketing, enabling passengers to board public transit vehicles by tapping their cards or smartphones on a reader.

NFC technology offers several advantages, including convenience, security, and speed. It eliminates the need for physical contact, reducing the risk of germs and bacteria. NFC transactions are also secure, as they use encryption to protect sensitive data. Additionally, NFC enables fast and seamless interactions between devices, enhancing the user experience. However, NFC has limitations, such as its short range and the need for both devices to be NFC-enabled. Despite these limitations, NFC technology continues to evolve and expand its applications, making it an essential component of the modern digital landscape.
