What is RFID?

Tags

Tags used in RFID technology receive the radio waves sent by the reader and send the data they store to the reader. Tags which establish a wireless connection between the product and the data management system are basically of two types: passive and active tags. Passive tags do not have any internal power source; they operate with the power they get from the reader. They can be used comfortably in places where reading range is narrow.

Furthermore, since they do not have any internal power source, passive tags are smaller in size and they can be easily integrated to small objects such as ID cards, key rings, books, buttons, CDs and DVDs. Active tags have internal power source. There fore they can be used in wider areas, under water, in trucks, containers and many other environments where radio frequencies are transmitted more difficultly. They can be identified by the reader easily from hundreds of meters. Active tags can be used easily and safely in product tracking, cargo and all stages of supply chain.

Readers

A reader is a device which sends radio signals through its antenna. When the radio waves sent by the reader arrive at the tag, the data on the tag are sent to the reader and identification process is completed.

Various types of readers enable us to develop different solutions for different needs. The reading range is determined by several factors such as the type of the tag, its location on the product, position of the reader antenna and height of the radio frequency. Readers can be stable or portable. The readers, which can be mounted on gates, used on desktops or portably, can be adapted to your needs and demands.
