NFC stands for Near Field Communication. It is a short-range wireless technology that allows two devices to communicate with each other by exchanging data when they are brought within close proximity. The maximum distance for NFC communication is about 4 inches.
NFC is used in a variety of applications, including:
- Mobile payments: NFC can be used to make payments with your smartphone. When you tap your phone against a payment terminal, the NFC chip in your phone sends your payment information to the terminal.
- Data sharing: NFC can be used to share data between devices, such as contacts, photos, and files.
- E-tickets: NFC can be used to store e-tickets, such as train tickets or concert tickets. When you tap your phone against the ticket reader, the NFC chip in your phone sends the ticket information to the reader.
- Access control: NFC can be used to control access to buildings or rooms. When you tap your phone against an NFC reader, the NFC chip in your phone sends your identification information to the reader.
NFC is a secure technology. The data that is exchanged between NFC devices is encrypted, so it is not possible to intercept the data.
