Near Field Communication (NFC)
NFC is a specialized subset of RFID technology that enables short-range, high-frequency wireless communication between devices (usually within 4 cm). It allows for secure, two-way interactions between electronic devices, making it the primary technology behind "Tap-and-Pay" systems and contactless data exchange.
Working of NFC Tech
- Proximity-Based: NFC operates at a frequency of 13.56 MHz. Because of its extremely short range, it is inherently secure against "eavesdropping" from a distance.
- Magnetic Induction: It uses two loops of wire: one in the reader and one in the tag/phone. When brought close, they create a magnetic field that transfers both power and data.
- Operating Modes:
- Reader/Writer: ....
