Fingerprint Readers for ID and Access Control

May 11, 2011 - PRLog -- Fingerprint readers take impressions of the friction ridges of the skin on the underside of the tip of the fingers. Fingerprints are used to identify you and are unique and different to everyone and do not change over time. Even identical twins who share their DNA do not have the same fingerprints. Police and Government agencies have used these modes of identifying humans for many years but other agencies are starting to use biometric fingerprint readers for identification in many different applications.

Fingerprints are formed when the friction ridges of the skin come in contact with a surface that is receptive to a print by using an agent to form the print like perspiration, oil, ink, grease, etc. The agent is transferred to the surface and leaves an impression which forms the fingerprint. There are several methods of biometric fingerprinting. A live-scan device basically reads or photographs fingerprints by measuring the physical difference between ridges and valleys. The procedure for capturing a fingerprint using a sensor consists of rolling or touching with the finger onto a sensing area, capturing the difference between valleys and ridges using a reader.

In order to “lift” latent prints it is necessary to use a developer like a powder or chemical reagent to develop or produce a high degree of visual contrast between ridge patterns and the surface on which it was left. There are many different types of chemicals used in developing fingerprints and choosing one depends on the agent used to make the fingerprint.

There are advances in the industry to form an SKP fingerprinting technique which is non-contact and does not require the use of developers, has the potential to allow fingerprints to be retrieved while still leaving intact any material that could subsequently be subjected to DNA analysis.

Besides forensic agencies, many companies are turning to fingerprint readers to identify employees and potential security threats, as in airports and government agencies. Military personnel records will contain scans of fingerprints or toe prints to identify bodies in trauma scenes and possible situations where fire victims’ fingerprints have been burned.The computer hardware industry has used fingerprint readers / scanners for years and the automotive industry is starting to catch on to the idea to identify their owners.

Other arenas where fingerprinting is starting to make an impression are in schools in the UK and are making their way to the US are used for electronic registration, cashless catering and library access. Whatever the application, fingerprints are the most commonly used forensic evidence worldwide. With many advances in the industry year after year, we will be seeing more fingerprint readers for identification in our daily lives as time moves on.
