What are Biometric Clocking In Machines?
Biometric clocking in machines use detailed measurements of the human body as a means of verifying the identity of the person clocking from amongst the records stored in the clocking device. Clocking on using your hand, fingerprint or facial image is an alternative to using a proximity RFID clocking card or fob, paper punch card or written completion of a timesheet.
To use a biometric clocking terminal your biometric details must first be registered on the device. You will be asked to present your hand, fingerprint or face to the terminal two or more times for your unique details to be recorded. The key details of your biometric profile are stored as a ‘template’ on the device. These are a series of numbers that record things like the position of the corner of your eyes in relation to the end of your nose or the width of your index finger at various points. Biometric clocking terminals do not record every tiny feature of your hand, fingerprint or face although some models may take your picture for a human to view at a later date.
Once your biometric ‘template’ has been recorded you can use the clocking terminal to clock on and off. You may need to enter a PIN and in some circumstances use a proximity card before placing your hand or finger on the terminal. When you place your hand or finger on the terminal or stand in front of a face reader the terminal compares your features to either the template associated with your PIN/card or all of the templates stored on the device. If it finds a probable match then the clocking terminal will indicate that you have successfully clocked.
Using biometric clocking as part of your time and attendance software system is a great way to eliminate the cost of issuing cards (and re-issuing lost cards) as well as ensuring your data is more accurate.
