KeyFob Classic Combi EM4200 and Mifare DESFire EV2

Robust, handy, secure—our proven Classic key fob in 125 kHz EM4200 and Mifare DESFire EV2 technology. Thanks to the good reading range of the EV2 transponder, user-friendly operation of Mifare reader units is guaranteed. Use in the encrypting mode, as well as EM4200 reader units in hybrid applications, is also supported.

Identification media such as key transponders are handled several times a day. They are used both indoors and outdoor—so good quality is essential. That's why the KeyFob Classic Kombi is made of high-quality Novodur plastic, so it is absolutely break- and kink-resistant. The ultrasonic welding of the lid part (pressure window) with the key fob ensures complete watertightness and makes it impossible to open the key fob. Thus, tampering can be eliminated.

The DESFire part comes pre-configured with sesamsec encoding or programmed project specific.

Keychain Classic The all-arounder

With our Classic key transponder, you are always on the safe side. Because as a true all-arounder, it can handle any demanding and multifunctional task. Thanks to the ultrasonic welding of the cover part, its housing is very robust and resistant to bending and breaking. And a lot is also possible in terms of visual design: personalized engravings and laser markings. Or standards, such as numbering, which is applied to the transponder under laminate using the thermal transfer process. We will also be happy to advise you on the selection of possible RAL colors and other versatile design and personalization options.

Another plus: the Classic is absolutely waterproof, which makes it ideal for leisure and swimming. Also important in this context: tampering with the transponder can be ruled out, as opening the key fob is impossible.
