NFC - Page 3

NFC, or Near Field Communication, is a short-range wireless communication technology that enables the transfer of data between devices over a distance of about 4 inches (10 cm) or less. It allows devices such as smartphones, tablets, and contactless payment cards to communicate with each other by simply being in close proximity. NFC operates on the principles of electromagnetic induction, allowing for the exchange of small data packets between compatible devices.NFC is commonly used for applications such as mobile payments, where users can tap their smartphone against a payment terminal to complete a transaction. It is also used in access control systems, where users can unlock doors with an NFC-enabled card or device, as well as for transferring files, pairing devices, and for smart posters that provide additional information when scanned. The technology is designed for convenience, speed, and security, making it a popular choice for a variety of consumer and business applications.
