What Is RFID And How Does It Work?

What Is RFID ?

The RFID is a technology that uses radio waves to transfer data from an electronic tag, called RFID tag attached to an object, through a reader for the purpose of identifying and tracking the object.

How Does RFID Tags Works ?

Each tag has its own “read only” or “rewrite” internal memory depending on the type and application. A typical configuration of this memory is to store product information, such as an object's unique ID manufactured date, etc. The RFID reader generates magnetic fields that enable the RFID system to locate objects (via the tags) that are within its range. The high-frequency electromagnetic energy and query signal generated by the reader triggers the tags to reply to the query; the query frequency could be up to 50 times per second. As a result communication between the main components of the system i.e. tags and reader are established. As a result large quantities of data are generated. Supply chain industries control this problem by using filters that are routed to the backend information systems.

In other words, in order to control this problem, software such as Savant is used. This software acts as a buffer between the IT and the RFID reader.
