What is a fingerprint scanner
A portablet fingerprint scanner is the most common and basic, most consistently developed and most commonly used method of identification in biometric security systems.
The fingerprint scanner uses a sensor to capture an image of your fingerprint.
Function of fingerprint scanner
Each of us has a fixed pattern on our fingers, and each person's pattern is unique and fixed. This genetically determined biometric feature will be well used in biometric solutions
How fingerprint scanners work
The main goal of a fingerprint reader or scanner is to generate biometric templates for the fingerprints submitted to it for scanning. It first captures a digital image of the fingerprint, called a real-time scan. This live scan is then digitally processed to generate the corresponding biometric template. The biometric template is what the fingerprint recognition solution uses when it is provided with a fingerprint scan for matching.

Types of Fingerprinters
Capacitive Fingerprinters
Capacitive fingerprint recognition uses silicon crystals and a conductive subcutaneous electrolyte to form an electric field, and the high and low undulations of the fingerprint cause different changes in the pressure difference between the two, by which accurate fingerprint determination can be achieved. This method is highly adaptable and has no special requirements on the usage environment, and the space requirement of the silicon element and the related sensing element is within the acceptable range of the cell phone design, which makes this technology popular in the cell phone.
The current capacitive fingerprint module is also divided into two types: scratch type and press type. Although the former occupies a smaller volume, it has a great disadvantage in terms of recognition rate and convenience. This also directly leads to manufacturers all locking their eyes on the more casual operation and higher recognition rate of the press type (capacitive) fingerprint module.
However, the capacitive sensor also requires a high level of finger cleanliness (relatively low compared to the optical type), and the sensor surface is made of silicon, which is easily damaged.
Optical fingerprint instrument
Optical fingerprint scanner recognition is a kind of fingerprint identification technology which is applied earlier, for example, many attendance machines and access control are using the optical fingerprint identification technology before. Mainly is the use of light refraction and reflection principle, the finger on the optical lens, the finger in the built-in light source irradiation, light from the bottom to the three prisms, and by the prism shot, shot light in the finger surface fingerprint uneven line pattern refraction angle and reflected back the light will be different. The prism is projected on the CMOS or CCD of the charge-coupled device, resulting in a digitalized, algorithmically processable multi-grayscale fingerprint image with black ridges (lines of a certain width and direction) and white valleys (depressions between lines). The database is then compared to see if it is consistent.
The disadvantage of optical recognition is that this type of fingerprint module has certain requirements for the temperature and humidity of the environment, and can only reach the epidermis of the skin, but not the dermis, and is influenced by the cleanliness of the finger surface. If the user's finger is sticky with more dust or wet finger, there may be a situation of recognition error. And it is easy to be deceived by fake fingerprints. For users, it is not very safe and stable to use.

Stagnation
Stagnation also becomes single finger fixed collection, the machine that needs single finger recognition only needs to use the registered fixed one finger for recognition
Rolling
Rolling, also known as rolling, is usually used for fingerprinters with large acquisition windows. Using the finger rolling acquisition to generate images, this kind of fingerprint requirements will be higher, because in the process of rolling acquisition, once the fingerprint image error, the acquisition failure.

Applications
ID card solutions
Traditional ID cards will be significantly downgraded to obsolescence. Most people are realizing that fingerprint-based access control is more effective than traditional ID cards in both enrollment and operational conditions.
Fingerprint-based swipe in and swipe out mechanisms in offices are being integrated with time and attendance management systems by installing fingerprint readers at entrances and exits for employee identification. Such a system eliminates traditional punch cards and proxy attendance that have been plaguing HR departments.
This improves the overall efficiency of employee access, identification, timekeeping and attendance, while providing more convenience to employees and eliminating the need for them to carry ID cards around the office.
Law Enforcement Agencies
Law enforcement is experiencing a technology revolution around the world. One of the technologies at the forefront of digital work is the use of biometric fingerprint readers to uniquely identify individuals.
Biometric fingerprint readers are favored not only because of their ability to capture fingerprints, but also because they can match those fingerprints to recorded data and identify perpetrators.
Increasingly, police and forensic departments are now more willing to carry mobile fingerprint readers to crime scenes to speed up investigations.
In addition to using fingerprints to apprehend criminals, law enforcement agencies are realizing the importance of fingerprint-based access controls in limiting access to confidential and sensitive data.
One of the easiest ways to restrict access to computers used by police departments is through portable USB fingerprint readers. When a USB fingerprint reader is enabled, only personnel with pre-configured access rights can access the data.
This not only helps protect sensitive records from theft, but also regulates the amount of information individuals can view.
Background checks
Using fingerprint scanners to determine the authenticity of employees can help detect people with criminal records and prevent identity fraud.
Once the subject's fingerprints have been scanned, they can be compared to various online databases containing biometric information about the candidate, such as citizenship records and police records, to obtain their correct background details. This fingerprint-based system will reduce the weeks of tedious manual or call-based verification that most background check organizations follow.
Hospitals and Clinics
Healthcare organizations make heavy use of fingerprint-based access control, especially in departments such as geriatrics.
Geriatric hospitals and homes primarily serve older adults. Many of these elderly patients suffer from age-related conditions such as dementia, Alzheimer's disease and related disorders, which predispose them to memory loss and subsequent unconscious departure from their homes. Therefore, it is important to control access and automated visits for such patients. Biometric fingerprint readers installed at entrance and exit locations can uniquely identify such patients when they attempt to leave and sound an alarm.
In addition to patients, fingerprint-based access control can be used for residents, staff and even visitors, who can check in at the reception desk using fingerprint readers. Hospital staff can obtain a different level of authorization than residents. Depending on the purpose of the visit, visitors can only choose to enter a limited number of public or private wards. The hospital needs to store the authorization information in a central server. Authorized access can then be enforced in a straightforward manner by placing fingerprint readers at the entrance to all areas requiring prior authorization and connecting these fingerprint readers to the central server.
Now that USB fingerprint readers are also available, setting up this advanced security system in hospitals has become much easier and more user-friendly. Fingerprint readers and fingerprint-based time and attendance systems enable patient safety and information security.
Point-of-sale (POS) Systems
Retailers must deal with many issues related to security and identification, one of which is the security of their point-of-sale (POS) systems.
These POS systems store a large amount of sensitive information such as personal details of customers as well as business information such as sales data, costing, customers, profit margins, etc. This information is sensitive to the financial and integrity of the company. It is important for every organization to use access controls to protect this information.
Traditionally, each retail store provides its employees with a unique identification number or pin. Since typical point-of-sale systems are susceptible to intrusion, theft or change of passwords has caused significant losses to companies. For this reason, many retail organizations are now adopting biometric fingerprint-based devices to efficiently and seamlessly identify employees.
From the design phase, fingerprint scanners are integrated into many retail software and point-of-sale hardware.
School Lunch Lines
Instead of ID cards and PINs, fingerprint scanners can be used to manage school lunch lines. Here is how fingerprint scanners can be used to control school lunch lines.
School children can be naughty and may damage the fingerprint reader.
Using a biometric security device that does not involve cash will reduce children's mishandling of money. Even if a child forgets their ID or PIN, a fingerprint-based access device can manage access.
Fingerprint scanners can be installed at the beginning of the lunch queue. One needs to ensure that children are allowed to join the queue only after their finger has been swiped and their identity confirmed.
Installing biometric security devices in school buildings will enhance security and discipline.
Fingerprint devices use algorithms to store fingerprints in a database in the form of templates. Thus, the possibility of hacking and misuse of student fingerprints is completely eliminated.
Gymnasiums and Fitness Centers
In gyms and fitness centers, fingerprint-based identification systems add convenience because members do not need to carry their membership cards and keys and then run the risk of losing them. Just their fingerprints are enough to prove their identity to gain access.
Fingerprint-based door locks in gyms allow the gym to potentially remain open 24 hours a day. People can come in at any time of the day or night to work out, even if the staff is not available. This business growth can easily offset the costs involved in setting up fingerprint readers and supporting servers.
To verify their identity to gain access, each member must place his or her finger on a fingerprint scanner and enter a 10-digit code. Their fingerprint and the code are combined to gain access to the center. The entire authentication process takes a few seconds and is user-friendly, rather than using a physical card. Fingerprint access control can also be extended to locker access in the gym, making locker handling much easier.
When a member enters using their fingerprint, this access information is recorded in a secure database. By integrating the security database with the gym's attendance management application, attendance and timekeeping for employees as well as members can be automated. This integrated system can then be programmed to check for expired memberships and send appropriate alerts when such members present their fingerprints to gain access.
Fingerprint reader-based access control can greatly enhance the overall member experience. It also helps management to manage the overall operations of the gym and take care of its members in a more efficient manner.
Hassle-free Cashless Transportation
One of the things that always adds to the Monday morning blues after a fun-filled weekend is the line for transportation to work.
Waiting in line for a cab, counting pennies for a bus ride or waiting for a ticket for the daily train commute is tedious, to say the least. The good news is that with the help of fingerprint scanners, your travel woes may soon be a thing of the past.
In the case of public transportation, these fingerprint scanners can work wonders. Instead of using actual cash or credit cards and waiting in long lines, all you have to do is swipe your finger across the scanning device.
The fingerprint scanner will read your fingerprint and link it to your bank account. Your bus ticket, cab or subway pass will be charged directly to your account. This results in a hassle-free and cashless transportation service.
In addition, the scanner uses fingerprints to ensure that there is no possibility of fraud and that the security of your financial information is at your fingertips.
Presidential Elections
Before fingerprint recognition was largely popular, some large election campaigns were conducted by manual checking and manual voting. Using manual checking may have some errors on the election results and will waste a lot of manpower and effort. But Huifan Technology's 7000 Bluetooth fingerprint instrument solves your so painful point.
