RFID transponders

RFID (radio-frequency identification) designates a technology for transceiver systems and for the “contactless” (inductive) identification and localization of objects and life forms by means of radio waves (i.e. electromagnetic waves). [Wikipedia]

The entirely passive transponder does not contain a battery and is supplied with power by the electrical field that originates from the reader. This ‘contactless’ technology makes handling very easy indeed, and reduces contamination and wear.

A high proportion of the RFID transponders manufactured by MADA are used frequently in systems for time and attendance (i.e. working hours) or access control. They could be described as a further development of the door key. One advantage is that locks with transponder systems are much easier to open than conventional, purely mechanical, kinds of lock system. If a transponder gets lost, a block is put on that transponder – a simple process – after which it can no longer be used. It is also easy to establish at what times access is granted to a given transponder.

In addition to digital lock systems, our transponders can be used for anti-theft systems, to measure times at sporting events, to identify individuals, for goods identification in the logistics sector and as an ID medium in motor vehicles.

The passive transponders in credit card size (ISO 7810) are used primarily for personal identification. The areas of use include access control and time recording systems, and they can also be used for the billing of services and the purchase of goods.
