Contactless smart cards
An increasing amount of applications is
using the principle of contactless communication between card and card reader.
Syscor supplies cards and other contactless devices for most technologies in this area.
RFID stands for radio frequency identification. This technology allows transmission of data without contact and line of sight from a data medium, what is called a transponder, to a reader and vice versa. A RFID system consists of three components: a RF Reader, an antenna and a transponder which is electronically programmed with unique data.
There are several frequencies that are used for RFID:
Contactless cards are produced as multi-layer
laminated cards and can be delivered as well as simple plastic cards with
individual prints and additional features (e.g. signature panel, hologram).
Syscor offers most contactless devices in the area of low communication
frequencies (125 kHz) as well as devices for high frequencies (13.56 MHz).
