What is the better device to use in a time and attendance monitoring situation where you want to have proper controls on the employees and eliminate all buddy punching? Should you be using a fingerprint scanner or a biometric time clock? Both of these devices are very accurate and infallible when it comes to ensuring that it is indeed the employee themself doing the punching in. Eliminating buddy punching is a big concern in many, many companies so it is important to pick the right device.
Fingerprint scanners have been the folklore of spy movies and James Bond for years but recently they have become entirely mainstream. They are installed in many laptops these days to facilitate signing in by using a finger instead of a password. Fingerprints give humans a built-in unique employee time card to be used for uniquely identifying each person and thus each employee. The pattern of ridges and "valleys" on the tips of fingers make it easier for hands to grip things, very much in the same way as a the tread pattern on a tire helps it grip the road. Fingerprints are a unique marker for a person, even an identical twin. (I should know). Two fingerprints may look the same at a glance but a trained investigator, or a sophisticated piece of time and attendance software can pick out clear, unique, definable differences.
Biometrics refers to specific authentication techniques that rely on measurable physical characteristics of the person seeking authentication. Biometrics are used in time clocks in order to accurately and uniquely identify each employee and avoid issues such as buddy punching. Biometrics are much more reliable than older methods such as time cards. Click here for information on biometric time clock.
I invite comments on which system works better for solving buddy punching and ensuring a sound time and attendance system.
