General Information

Transponder, Reader

RFID systems are finding their way into more and more segments of industry and public life. With ePayment and ePassports, RFID technology ensures greater security, user-friendliness and speed. It also allows contactless identification of animals and products using transponders.

A transponder consists of a microchip with control logic and data storage (and energy storage in some cases), as well as a sending / receiving antenna. The transponders are fully integrated into the relevant bases and housing types. The most common of these are the so-called "smart" labels; there are also tags and key fobs as well as ear tags for animal identification. These systems are exposed daily to adverse environmental influences such as moisture, extreme temperatures and pollution, and therefore set high requirements in terms of their development, manufacture and service life.

SMARTRAC produces fixed programmed transponders, that is data transmission systems with an exclusive read function, but also programmable transponders which allow processing of stored information.

In terms of our products, we distinguish between active systems, i.e. transponders that draw the energy they require for data transmission from a battery, and so-called passive systems which are powered by the reader's electromagnetic field.

The data transmission range depends on the type of transponder and the relevant frequency.
