Best Biometric Fingerprint Scanner Reviews 2017

A biometric fingerprint scanner is a useful device for individuals as well as business owners who want to augment security and prevent unauthorized access and use. Most devices are based on a USB interface and are easy to install. Price primarily depends upon the level of security that one wants to establish. Each device follows a generic identification process but the sensitivity and locking mechanism differs. For a prospective buyer, there are lots of options available from door locks to laptop security devices. Consequently, one should conduct a bit of research before making a purchase decision.

For individuals who want biometric fingerprint scanners for their laptops should go for Dell’s opti-mouse which has built in scanning technology that can provide adequate security for one’s laptop or personal computer. On the other hand, business owners require devices that can be installed upon doors to restrict access as well as provide a basis for noting down the attendance of employees. For such individuals, the Wasp Tech’s time and attendance biometric device is extremely useful.

A biometrics fingerprint scanner provides a lot of benefits to a number of users with differing requirements. For home owners, the biolock deadbolt fingerprint lock is an extremely good option because it provides security as well as negating the hassle of having to keep a spare key or having to memorize keypad combinations. On the other hand, office owners want something which is more sophisticated and technologically advanced. Consequently, these individuals can go for a biometric fingerprint ID door lock with a keypad. This biometric fingerprint reader is an extremely advanced device and can provide high tech security to small as well as large businesses.

Some people also carry around restricted and sensitive information within their USB flash drives. Consequently, there can be situations where the flash drive might end up in the wrong hands. A simple password protection system would not be adequate enough to restrict a person from accessing the files. Hence, a biometric security flash drive can provide significant security. It works in exactly the same way as a normal fingerprint scanner and only allows access to the rightful people.

Home owners who want to further augment their biometric security systems have the option of opting for a device that supports both a fingerprint scanner as well as a keypad lock. Most devices also have inbuilt systems that can automatically notify nearby police stations if a person enters the wrong keypad combination or fingerprint three times consecutively.

How a Fingerprint Scanner Works

Fingerprint scanners are biometric devices that can be used by all sorts of individuals to beef up the security for their homes or business offices. Initially these devices were extremely expensive and could be afforded by large companies as well as military and governmental organizations. However recent technological advancements have resulted in considerable cost cuts which have allowed manufacturers to provide these devices at a significantly lowered cost. A fingerprint scanner is the ideal gadget for a variety of scenarios such as being installed as a door lock, laptop/desktop computer protection as well as safe locks. There are specific models that are equipped with additional security measures such as a keypad combination generator and a smart card reader.

A biometric fingerprint scanner normally consists of a scanning device, a microprocessor as well as a database. The device that links the 3 components is the microprocessor which processes scanning of fingerprints and linking them with the database. Every individual human being has a distinct fingerprint. This is because each fingerprint has a distinct set of contours and ridges. A scanner device has the ability to detect these ridges and contours thereby establishing identification. On the other hand, the database consists of various fingerprints that have been stored within the device. The fingerprints are also linked with various identifiable details such as social security number, ID number, address and so on. This information helps the device to identify the particular individual.

Basically the microprocessor in conjunction with the scanning device scans a particular fingerprint and attempts to match it with the set of fingerprints stored within the database. If the fingerprint matches the stored information, the device identifies the person and allows entry. On the other hand, if the scan is unsuccessful then the device automatically seals the door and notifies concerned authorities of a break in attempt. This is done so as to enable individuals to identify the person attempt unauthorized entry.

Biometric fingerprint scanners are extremely useful devices because they can be used for a variety of purposes. Some people use them as door locks with an additional keypad. An individual seeking entry will have to pass the fingerprint scan as well as punch in the correct keypad code. On the other hand, USB devices can be used to protect laptops as well as desktop computers. Fingerprint scanners normally have the memory to save up to more than 70 fingerprints. Devices that have a larger capacity are obviously more expensive

Are Biometric Fingerprint Scanners Reliable

The ability to recognize fingerprints can be incredibly useful in several different situations and a fingerprint scanner does just that. This witty device identifies fingerprints using its sensors and a range of different mathematical procedures.

Minutia and pattern algorithms are sometimes used in fingerprint scanners for the purpose of identification. A pattern algorithm determines the pattern of a fingerprint, which can either be a whirl, an arch or a loop. Then minutia algorithm examines the ridges of a fingerprint. This includes looking at where ridges end and where they split, and whether the fingerprint has dot or short ridges.

A scanner fingerprint can also be made using a sensor or detector. An optical detector, for example, can capture the visual picture of a fingerprint using digital imaging.  An inactive capacitance detector does this using pixels, while an active detector uses electricity and an ultrasonic detector makes use of ultrasonography to form images.

These scanners are also known as biometric fingerprint scanners because they recognize fingerprints using biometrics. Biometrics is basically the name given to scientific methods, which are used to spot the distinctive traits or characteristics of different human beings. This can be anything from face recognition to iris recognition, fingerprints to DNA or even someone’s unique scent.

Everyone has their own distinctive fingerprint, which isn’t the same as anyone else. Even twins who are identical don’t have matching fingerprints. The ridges found in every fingerprint are unique and different ridge patterns help identify different individuals.

These scanners are used in several places. The police use them to identify suspects and victims while high-security buildings use them to prevent illicit access. They are also used in some private homes, which require extra security to prevent access to specific rooms, or containers where valuables are stored.

When law enforcement agencies need footprint detectors, they don’t use images. They need a much more accurate and sophisticated method so algorithms are used to compare a range of different fingerprints. If the algorithms identify a large number of similarities between two fingerprints, they are considered a match.

Although fingerprint scanning is valuable, it’s not a perfect method of identification. Some scanners, like the optical detector type, aren’t as reliable and can produce false results at times. Moreover, a fingerprint scanner can be tricked if, for example, a criminal gets a copy of someone else’s fingerprint and uses it instead of his own.
