Introduction

AS3956-ATWM-S4 is an RFID Transponder Tag based on the technology of an Automatic Transfer Window (ATW) for storage and transfer of data. It operates on the principle of using radio frequency signals (RF) to transmit data for identification and authentication purposes. This article will discuss the application field and working principle of this product.

Application Field

AS3956-ATWM-S4 is mainly used in a wide range of applications including supply chain management, personnel tracking, asset management, building access control, and security access control. This product is especially useful in retails and supply chain applications due to its ability to provide a non-intrusive and low-cost method of data gathering and tracking. It is also an ideal solution for applications that require authentication such as access control, and asset management.

Working Principle

AS3956-ATWM-S4 utilizes an ATW which consists of a chip, an antenna, and a behavioral interface. The chip contains a set of functional units and a non-volatile memory. These functional units execute the command sent by the RF transmitters. The command can be read, written or modified in the memory. The antenna is responsible for receiving and transmitting data.The data transmission process starts with the reader sending out a signal containing specific commands in the form of a carrier wave. The antenna of the AS3956-ATWM-S4 transponder will capture the signal, decode it, and send it to the chip. The functional unit of the chip will calculate a new variable from the data received and use it to drive or modify data from the non-volatile memory. After the data is processed, the chip will transmit the answer back to the reader via the antenna.

Conclusion

In conclusion, AS3956-ATWM-S4 is an RFID Transponder Tag based on the technology of an Automatic Transfer Window (ATW). It is mainly used in supply chain management, personnel tracking, asset management, building access control, and other applications that require authentication. It works by receiving a signal from a reader, decoding the signal, processing it, and sending back an answer.
