Let's learn more about this technology in the following article. Table of Contents [ Show ] What is NFC? NFC (short for Near Field Communication) is a short-range wireless connection technology that allows devices to communicate and exchange data when they are close to each other, usually within a distance of less than 4cm. This technology is built on the principle of RFID (Radio Frequency Identification), but is integrated and improved to be more suitable for modern devices such as smartphones, smart cards, and IoT (Internet of Things) devices. NFC is not only a communication technology but also considered as a "gateway" to open many new applications in the fields of payment, data sharing, security, and automation . Therefore, NFC is becoming more and more popular and integrated in most modern mobile devices.

How NFC Works NFC technology works on the principle of electromagnetic induction between two antenna coils. When two NFC-enabled devices are placed close to each other, the connection process takes place in the following steps: Creating a connection : One device will send a signal (acting as the active device), and the other device will receive the iran email list signal and respond (acting as the passive device). Data Transfer : Once the connection is established, data is transferred back and forth between the two devices. Transaction completion : Data exchange is completed within seconds. One notable point is that NFC does not require a large power source, and in some cases, passive devices (such as NFC tags) can operate without a separate power source. Practical Applications of NFC 1.

Contactless Payment One of the most prominent applications of NFC is in the field of payments. With platforms such as Google Pay, Apple Pay, Samsung Pay and NFC-enabled credit cards, users only need to tap their phone or card on the POS (Point of Sale) machine, and the transaction will be completed in a snap. Advantages of NFC payments: Fast and convenient. No need to carry cash or plastic cards. High security thanks to data encryption technology. 2. such as photos, videos, website links, or contacts between NFC-enabled devices with just a tap. This feature is especially useful for quickly transferring information without using the Internet. 3. Authentication and Security NFC is widely used in authentication systems, such as employee badges, access cards, or smart door locks. This technology ensures access is only granted to authorized people, helping to improve security in the workplace or at home. 4.
