What is the Most Reliable Fingerprint Reader?

By Bob Mesnik

Fingerprint readers scan the features of a person’s finger and create a digital code that can be used as a unique digital template.  That’s the concept, but how do fingerprint readers actually work?

There are a number of different technologies used to scan the features of a fingerprint. The engineering challenge is to reliably read the ridges and valleys on the fingerprint so that it can be converted to a digital image.

This article reviews the most popular technologies that use Optical, Ultrasonic and Capacitive sensors.

Selecting the right biometric reader

By Dennis Gallen

Biometrics is a much safer way to control door access than carrying a card or remembering a pin number.  It’s more secure because you are identifying a person rather than something the person is carrying.  The door credential can be stolen, but your face can’t.

What can biometric readers do?  How do you select the right fingerprint reader, facial recognition system, or multimodal biometric system?  By the way, the latest Biometric IP reader-controllers combine a number of physiological characteristics and are more flexible and reliable than the older units.   There are a lot of different choices, but what is best, what provides the best reliability and repeatability? This article examines the technology and provides guidelines for selecting the right biometric system.
