What is a RFID transponder?

Radiofrequency identification (RFID) can be used for a variety of purposes, including the control chain management and the collection of road tolls. The RFID transponder is usually designed to detect the radio signal from another device and return the expected answer. In the RFID system, the transponder can be known as the brand and the device that communicates with it is called a reader. There are three main types of RFID transpond, including passive, half -space and active. The main difference between these types of RFID transponder is that some can work without battery, while others require an internal energy source. Readers and brands use radio signals that are generally limited by distance than a line of sight. The reader device usually sends a questioning signal that any mark can receive, process and then answer. This can allow inventory management without the need for physical catalog items or to create a record of a driver passing through a toll zone without ever having to stopVit.

RFID passive brands are usually able to work without any internal battery source. This type of RFID transponder can be turned on and on by electromagnetic radio waves sent by a reader. The power can then be used to process the signal and return the response. Since no battery source is present in the passive RFID transponder, there may be less concern that the brand has a short operating life.

both semi -picked and active brands use some form of internal energy source. Semi-pre-constructive marks usually require an external signal from the reader that is activated, almost the same as a passive RFID transponder. The presence of a battery source can significantly extend the transmission energy and increases the seg range and reduce the possibility that the brand will miss the reader. Active tags also use an internal power supply and usually look for a reader signal to respond in the event of a needwould be.

Despite the potential benefits for managing the supply chain, transport, payment systems and other areas, there are potential problems with RFID transponders. Many people have raised concerns about security questions, especially in cases where the RFID transponder can be used to identify a person. Since the communication between the brand and the reader occurs within the radio waves, there may be the potential for signal capture and the identification of theft.
