NFC technology relies on two key components: the NFC tag and the NFC reader. The NFC tag can be embedded in various objects, such as credit cards, smartphones, or NFC-enabled accessories. The NFC reader is the device that initiates and maintains the communication with the NFC tag.

When an NFC-enabled device, such as a smartphone, comes into close proximity to an NFC tag, the devices create an electromagnetic field between them. This process is known as “coupling.” The tag and the reader exchange information by modulating and demodulating the electromagnetic field.

NFC operates in two modes: active and passive. In the active mode, both the NFC device and the tag generate their own electromagnetic fields, allowing for bidirectional communication. In the passive mode, the NFC device generates the field, and the tag only responds to the field, enabling unidirectional communication.

There are three main types of NFC communication modes:

1. Read/Write: In this mode, the NFC device can read information from an NFC tag and write data to it. For example, in contactless payment systems, the NFC device reads the card information stored on the NFC tag and sends payment instructions to the payment terminal.
2. Peer-to-Peer: This mode allows two NFC-capable devices to exchange data between each other. It enables functions such as file sharing, contact sharing, and device pairing.
3. Card Emulation: In this mode, an NFC-enabled device can emulate an NFC card or tag, allowing it to be used for contactless payments or access control. The device behaves as if it were an actual NFC card or tag when brought into contact with an NFC reader.

NFC technology offers convenience and versatility for various applications. It simplifies processes such as mobile payments, ticketing, access control, and data transfer, providing a seamless and user-friendly experience.
