Near Field Communication (NFC) is a short-range wireless technology that allows communication between devices within 10 cm of each other. NFC operates at 13.56 MHz and transmission rates ranging from 106-424 Kbit/s. NFC supports both active and passive communication modes. Potential applications of NFC include contactless payments, data sharing, and device configuration. While security threats are present with NFC, establishing a secure channel can protect against eavesdropping and data modification attacks. NFC is expected to transform everyday tasks and be widely adopted in the future.
