The premise of this type of security system provides business owners with a unique security barrier to keep track of authentication, monitor attendance of personnel and keep your property safe and secure. This increasingly prevalent method of security can come in multiple forms, such as facial, iris and DNA recognition, but the most popular design of biometric security due to its simplistic design, yet advanced security restrictions is the biometric finger scanner.
In this post, we outline exactly how biometric finger scanners work and why business owners should consider a biometric form of security for a top-class level of protection at ievo. Biometric finger scanners are operated by a control board dedicated to providing a powerful, fingerprint matching system that is designed to support internal, or external fingerprint reading units.
The control board acts as the main point of communication between the biometric scanner and the fingerprint, providing a highly reliable fingerprint matching system. Once the biometric finger scanners are installed and the control board has registered all relevant personnel, entering the premises either internally or externally, the optical sensor will scan and capture a fingerprint, to either grant or deny access.
The process of scanning a fingerprint varies from the model of reader, but at ievo , the optical scanner uses both polarised and non-polarised lights to register between reference points, building a high grade, completely accurate fingerprint image to provide an extremely precise reading.
Specific data from the fingerprint image captured is converted into a digital template which is then used for identification. As many consumers complained at the time, this method was very finicky and often required several attempts to scan the result correctly. Fortunately, these days, the simple press and hold design is the default setup.
You can do more than just read fingerprints with these scanners, however. Newer models sport gesture and swipe functionality too. These can be used as soft button support to act as navigation keys, force sensing capabilities, or as a way to interact with other UI elements.
However, premium-tier smartphones have moved on to in-display technologies. The latest fingerprint scanning technology to enter the smartphone space is the ultrasonic sensor. Qualcomm and its Sense ID technology are a major part of the design. In fact, Qualcomm is now on its second generation of Ultrasonic fingerprint scanning technology technically its third product.
It promises a bigger reading area and faster processing speeds. To actually capture the details of a fingerprint, the hardware consists of both an ultrasonic transmitter and a receiver. An ultrasonic pulse is transmitted against the finger that is placed over the scanner.
Some of this pulse is absorbed and some of it is bounced back to the sensor, depending upon the ridges, pores, and other details that are unique to each fingerprint. Instead, a sensor that can detect mechanical stress is used to calculate the intensity of the returning ultrasonic pulse at different points on the scanner. Scanning for longer periods of time allows for additional depth data to be captured. This results in a detailed 3D reproduction of the scanned fingerprint.
The 3D nature of this capture technique makes it an even more secure alternative to capacitive scanners. This is partly due to the reasons mentioned above. However, Qualcomm has addressed this with somewhat its second-generation technology. They can limit the ability of the scanner to read fingerprints correctly.
On the plus side, bezels are thinner than ever due to being able to hide the scanner under the display. Optical-capacitive fingerprint scanners are being used for this purpose too. The industry is currently split between these two. Optical-capacitive scanners address some previous security issues with optical designs. Top Advantages of Fingerprint Authentication.
