Near Field Communication, or NFC, is a short-range wireless communication technology that enables devices to interact with each other within a close proximity, typically within a few centimeters. It operates at a frequency of 13.56 MHz and can be used for various applications, such as contactless payment systems, secure access control, and data sharing between devices like smartphones, tablets, and other compatible gadgets.

How NFC works

When two NFC-enabled devices are brought close to each other, a connection is established, and they can exchange data with each other. This communication is enabled through NFC Tags and NFC Readers. NFC Tags are small integrated circuits that store and transmit data, while NFC Readers are devices capable of reading the data stored in NFC Tags.

NFC Modes

NFC operates primarily in three modes:

Security Concerns

While NFC brings convenience through its numerous applications, it also poses security risks, and it’s essential to be aware of these. Some possible concerns include:

Security Best Practices

To minimize the risks associated with NFC, follow these best practices:
