What is Biometrics?
Biometrics is basically a method of identifying an individual using any unique physical characteristics of their body. Biometric methods help in ensuring maximum accuracy in identifying a person.
What are the different types of Biometrics?
Biometric methods can be used in multiple ways, for different technologies & systems, like:
- Iris (eyes)
- Voice patterns
- Facial patterns
However, irrespective of the type of technology or system being used, ultimately all biometric methods have one thing in common - each system must be based on a single distinguishable physical attribute of the person.
Biometric Fingerprint Readers as a choice for Time & Attendance Monitoring
Though there is variety in the 'type' of Biometric systems, the Fingerprint method is the most widely used and popular form of biometric system used around the world. Over time in the last few years, there has been a huge improvement in technologies related to the hardware for Fingerprint readers, which has made the Fingerprint based biometric systems most accessible, efficient and affordable for small medium businesses. In fact, these days you get small/tiny fingerprint scanning devices for your own personal laptop too!
How does the Fingerprint reader work?
Every individual's Fingerprints are made of unique patterns and ridges formed in the skin surface of the fingers. A biometric fingerprint reader creates a high resolution image of these unique patterns of the person's fingers. Once the reader has recorded these patterns, it will ensure accurate recognition of the same person based on his/her unique fingerprints. Though the actual fingerprint identification process may vary between different products or systems, the fundamentals remain the same.
We've tried to summarize the different parts of a standard biometric fingerprint reader's identification process below:
Sensor: The sensor which scans the fingerprints is the most basic and primary part of the system.
Processor: Then there's a processor which stores the fingerprint images in a database
Database: The database is another important component of the device which stores reference numbers, PIN numbers, names, email IDs, employee number, etc. This data helps match and identify a fingerprint with an individual.
Screen + User Interface: depending on the type of device, there may also be a screen on board the device which will help users to operate the device via a keypad on the surface of the device.
Software: Of course, there will also be a software sitting inside the machine too. This software's one and only job is to compare and match the fingerprints with the individual's identification in the database on-board. In this case, it will be the sumHR software system! :)
