RFID transponders, tags, and readers are an important component of the Internet of Things (IoT) and various other industry sectors. The AS3956-ATDT-I3 is an RFID transponder designed to achieve high-performance standards in terms of performance, reliability, and cost. This article will discuss the application field and working principle of the AS3956-ATDT-I3.

Application Field

The AS3956-ATDT-I3 is a type of RFID Tag suited for applications such as smart NFC, access control, Asset Tracking, livestock identification, and others. It is a so-called transponder, which is an electronic device that receives and responds to a radio signal. This type of tag is based on the concept of Near Field Communication (NFC), which requires proximity of the chip to the reader in order to function. The tag is designed to enable reliable data exchange between the chip and the reader at 13.56 Mhz and is suitable for environments ranging from industrial to outdoor. It is also particularly suitable for outdoor environments, given its weather resistant design.

Working Principle

The AS3956-ATDT-I3 RFID Tag primarily consists of an antenna, a transmitter and a receiver, a modulator, and a controller, all of which are enclosed in a weather-resistant casing to protect the components from external conditions such as humidity and dust. The controller is responsible for controlling and managing the antenna, modulator, and receiver, enabling them to communicate with the reader and send back data stored in the tag’s memory.

When a reader device is brought close to the RFID tag, the antenna collects the energy received from the reader and transmits it to the modulator which modulates the energy and converts it into a signal that can be transmitted over the air. The signal is then received by the receiver and transmitted to the controller, which is responsible for interpreting the signal and responding back to the reader. If the data in the tag’s memory matches the reader’s request, the tag will transmit back the requested information. This is the general working principle of an RFID transponder.

Conclusion

In conclusion, the AS3956-ATDT-I3 is a high-performance RFID transponder designed for a wide range of applications, including smart NFC, access control, asset tracking, and livestock identification. This tag is based on the NFC concept, which requires close proximity of the chip to the reader for successful data exchange. Its main components include an antenna, transmitter and receiver, modulator, and controller, all of which are enclosed in a weather-resistant casing. The controller is responsible for controlling and managing the other components and enabling them to communicate with the reader.}
