Why Fingerprint Verifying Technology Become The Mainstream of Biometrics?

There are many kinds of biometrics technology until today, why fingerprint become the mainstream? The reason is that the fingerprint template data is smaller than other biometric technology data. The detachment fingerprint storage capacity is only about 120 to 180byte, such a small space requirement make it easy to be stored in most device, such as credit cards, passports, identity cards, Attendance Machine, Employee Time Clock, etc.

Fingerprint recognition has a good interactive experience, and also has many advantages, the main advantages are summarized as follows:

1. Need Little Storage Space: 
Storage of fingerprint template data is the smallest among biometrics technology, each fingerprint template only need about 120 to 180byte.

2. High Security: 
Except for identical twins, it is impossible to find two individuals who have the same fingerprints.

3. Convenient: 
Finger print feature is the "portable" ,which can be achieved conveniently and accurately interactive experience, and is easy to applied with computer security, monitoring, management, systems integration, automated management.

4. High Stability: 
Fingerprints is one of the most stable human biometric features. With development of fingerprinting technology, it bring huge potentialspace for biometrics market.whether it is substitute for password or unlock the phone, or mobile payment,or attendance management system,or door access system, fingerprint all have unlimited imagination. this article published by INJES Technology Co.,Ltd.

How Does Biometric Attendance Devices or Fingerprint Scanner Work?

Regardless of any Biometric Attendance System (biometric devices) or finger print equipment, the fingerprints collection are from two kinds of ways: Push and Sliding.

1. Sliding

Sliding your finger from the sensor, the system can get the entire fingerprint. When pressing finger prints, it unable to capture complete fingerprint image at one-time. During finger sliding from sensor, the sensor capture snapshots image for each section of finger,then splice these snapshots to from a complete image for fingerprint .

Sliding mode features advantages of low cost, ease of integration, can capture a large area image , the application of traditional feature points algorithm, but the disadvantage is that need customers to have a consistent standard action image acquisition, experience relatively poor, so the application promotion is not very successful, which with a narrow market .

2. Push / Press

Finger is floated on the device in order to obtain a fingerprint image. Usually in order to obtain the entire fingerprint, you must use a Fingerprint Scanner which larger than finger, and the whole finger should be pressed on the sensor.

Push mode features advantages of the good customer experience , with only one press can capture images , matching clients’ operating habits of mobile applications, no need teach customers how to use it. The disadvantages are: high cost, integration is difficult, can not get large finger prints image at one time, high security fingerprint algorithm is complex for some users.

Obviously, push fingerprint sensor is the easiest and most convenient one. More and more mobile devices,Employee Time Clock, will use push-type fingerprint identification program. Get the idea finger print equipment product at  injes.com .
