Selecting identification technology

In physical access control systems, reliable identification of people is crucial.
This article describes the most common ways in which people can be recognized using ID cards and Biometric identification when more security is needed. ID cards are available in many types, ranging from simple printed bar code cards to microprocessor-based RF cards.
Biometric technology has grown in maturity, and many systems based on fingerprint, face, hand or eye recognition are performing well in combination with physical access control. Selecting the right system is a process that includes the consideration of criteria like convenience, reliability, accuracy, installation, and costs.

This paper provides an overview of currently available technologies and their typical properties, which will hopefully be of assistance during your own selection process. The article starts with an introduction to several types of identification. The final section is about the selection process.
