NFC

NFC, or Near Field Communication, is a short-range wireless communication technology that enables the exchange of data between devices over a distance of about 4 inches (10 cm) or less. It is designed for simplicity and convenience, allowing devices such as smartphones, tablets, and contactless payment terminals to communicate with each other by merely being in proximity. NFC operates at a frequency of 13.56 MHz and typically supports data transfer rates of up to 424 kbit/s.

NFC technology is commonly used in contactless payment systems, allowing users to make transactions by tapping their device on a payment terminal. It is also utilized for pairing devices, sharing contact information, and accessing services such as tickets or loyalty cards. NFC is built on established RFID (Radio Frequency Identification) technology, but it is specifically designed for two-way communication rather than just one-way information retrieval.

The convenience of NFC has made it a popular choice for mobile payment solutions and various other applications where quick, secure, and contactless interactions are beneficial.
