BioKey INSIDE is a modular concept based on the new BioKey 4000 fingerprint recognition software. The failure rate of the biometric recognition has been reduced to such a minimal level that the user is hardly faced with any restrictions. The automatic learning feature is a further innovation: recognition performance improves continuously. The “modular design principle” is also groundbreaking. Thus, BioKey INSIDE comes not only as a fingerprint system, but also offers Bluetooth and keyboard versions. The appropriate products are simply combined and offered as a complete package. The design, materials used, interfaces, function and soft- and hardware can be configured to individual requirements.
