How Does NFC Technology Work?
This field powers the NFC reader, enabling it to communicate with the machine.
The NFC reader, acting as a target, also generates its own electromagnetic field.
The interaction between these fields allows for the transfer of data between the two devices.
The communication between an NFC reader and a gear occurs through a process known as modulation and demodulation.
The NFC-enabled gadget receives this modulated signal and demodulates it to extract the data.
NFC technology supports two modes of communication: passive and active.
In active mode, the equipment has its own power source and can actively communicate with the NFC reader.
One of the key features of NFC technology is its ability to support different types of data transfer.
NFC tags, which can be embedded in objects or stickers, store specific types of information.
Security is also a crucial aspect of NFC technology.
NFC readers and devices utilize encryption algorithms to ensure the confidentiality and integrity of the transferred data.
This helps prevent unauthorized access and protects sensitive information during transactions.
Overall, NFC technology provides a seamless and convenient way to transfer data between devices.
