Biometric access control card readers

Choosing a Biometric access control card readers should be a function of your company’s priorities and the reader’s function. Is your company’s most significant priority convenience of the biometric capture when a person requests system authorization? Many companies are concerned that the capture of biometric samples will slow access to vital facilities for repair and control functions; they therefore wish to find a system that, once implemented, can quickly and simply pass people through to their authorized destination.

You can imagine that, noting an emergency in the water treatment facility, company management would not want its authorized employees to waste time in accessing the facilities that need immediate repair or analysis. In this case, any biometric reading that forces its subjects to hold still for several seconds would be problematic. Retinal capture is clearly not the best solution.

In this instance, it may be best for your company to capture the biometric reading from a distance. If so, then fingerprints or iris scans would be impossible and you should consider voice recognition or facial geometry software. The biometric sample comparison settings in this type of situation would probably allow significant variation between the original sample and the access sample, so that the system unlikely would render false negative readings.

Conversely, your company’s priorities may run toward the highest level of security possible for access to controls in a nuclear facility, leading your company to choose a biometric authentication process that minimizes the possibility of false positive readings. Your business would therefore select a system and sample readers that are least likely to be fooled by a terrorist attempting entry to the secure facility, and you would be willing to trade speed of access for certainty of authorization. In this case, a retinal scanning system may be the best match for access control, while distance face readers would not be.

Always remember that the biometric authentication of Biometric access control card readers is used as part of a larger, more complex system. If your company plans to implement an intense security regime, it could always measure different sets of biometrics at different locations. For example, they could use voice recognition to enter the facility, while requiring retinal scans at the door to the control room or fingerprint readers to access the control computers.
