One device, the reader or active device, generates a magnetic field using its coil. The device communicates with payment terminals using the secure element, a dedicated chip that stores sensitive financial information.
Key Features and Functionalities The versatility of NFC capability stems from its ability to support multiple modes of operation, which define how devices interact. The short range of the technology is the first line of defense; a potential attacker would need to be in extremely close proximity to intercept the signal.
