NFC-tags are a carrier for storing and transmitting data based on near field communication. Near-field communication technology is a short-range, high-frequency wireless communication technology that allows electronic devices to exchange data contactless when in close proximity to each other, typically within 10 cm.

An NFC-tag typically consists of a chip that stores data and an antenna that communicates with the reading device.

When an NFC-enabled device is in close proximity to an NFC-tag, the tag is activated and interacts with the device through the principle of electromagnetic induction.

Operating frequency: The operating frequency of NFC-tags is usually 13.56MHz, which can achieve a high data transmission rate while ensuring the communication distance, and does not conflict with other common wireless communication technologies (such as Bluetooth, Wi-Fi, enz.) frequency bands, ensuring its compatibility in complex electromagnetic environments.

Storage capacity: The size of the storage capacity varies depending on the label type and purpose. Small NFC tags may be only a few hundred bytes long and are used to store simple identifying information, such as the ID number of an access card. Larger-capacity NFC tags can reach several kilobytes or more, and can store rich data, such as vCard information, URL links, enz.

Data transfer rate: Passive NFC tags have relatively low data transfer rates, typically at 106Kbps, 212Kbps, or 424Kbps. Due to their own power supply and signal amplification capabilities, active NFC tags can have higher transmission rates to meet the needs of fast data exchange.

Data storage function: NFC tags are capable of storing various types of data, such as text information, digital encoding, binary data, enz. This data can be user-defined or required for specific application scenarios, such as the price of goods, origin and other information.

Data transfer function: When the NFC reading device is close to the tag, the tag is able to transmit the stored data to the reading device. This transfer process is fast and convenient, without the need for complex pairing or setup processes, enabling instant access to information.

Trigger function: An NFC tag can act as a trigger device that, when read, triggers the device or app associated with it to perform a specific action. Bijvoorbeeld, triggering the phone to automatically open an app, switch to a specific setting mode, enz.

Mobiele betalingen: NFC tags play an important role in the field of mobile payments. Users simply hold their NFC-enabled phone near a payment terminal, such as a POS, to complete the payment process. This payment method is fast and secure, reducing the hassle of cash transactions, while also improving the efficiency and security of payments.

Access control system: NFC tags are widely used in access control systems, such as community access control, office building access control, enz. Users can hold a card or mobile phone with an NFC tag near the access control reader to verify their identity and open the door. Compared to traditional access cards, NFC tags are more portable and can be managed and updated through software.

E-ticketing: In the fields of transportation, entertainment, enz., e-ticketing is gradually becoming popular. Bijvoorbeeld, e-tickets for subways and buses, as well as e-tickets for concerts and cinemas, can all be realised through NFC tags. Passengers only need to hold their mobile phones close to the turnstile or ticket gate to complete the ticket check-in or entry, simplifying the ticketing process.

Smart Device Interaction: NFC tags can be used for quick connection and interaction between smart devices. Bijvoorbeeld, if you attach an NFC tag to the speaker, it will automatically connect to the speaker and play music when the phone is near. Or for the configuration of smart home devices, the network connection and parameter setting of the device can be quickly completed by proximity to the NFC tag of the mobile phone.

In short, NFC tags have been widely used in many fields with their unique technical characteristics and rich functions, and with the continuous development of technology, their application scenarios will continue to expand and enrich.
