Fingerprint machine is a general term, including fingerprint scanner, time and attendance equipment. Facial access control machines

How to choose the right fingerprint machine 

First of all, let's review what a fingerprint scanner is. A fingerprint scanner device is actually a high quality image that is captured from your finger and passed on to software that is written in code. This statement tells us that no matter how powerful your software is and how blocky the data transfer is, choosing the right fingerprint machine is the most important thing.
HOW TO CHOOSE Fingerprint Machine

1. What kind of computer operating system can the fingerprint scanner machine run on?

Fingerprint scanners with USB interface can generally be adapted to Windows, through the USB adapter can also be adapted to Type C interface on Android phones, but also a little can work in Linux and IOS system, this usually depends on the fingerprint scanner software situation

Windows fingerprint scanner devices:

HF7000, HFOS300, HFOS1000, HF4000, HF4000PLUS
The HF7000 is a Bluetooth portable fingerprint scanner with USB interface that works well with Windows.
HFOS300 is an optical two fingerprint scanning device, also with USB interface, compatible with Windows system.
HFOS1000 is a FAP20 certified optical fingerprint scanner with a compact body and a USB interface for Windows.

2. What software do I need to use for fingerprint machine?

No matter what system the fingerprint scanner is, it needs to be used together with software, they can't work by themselves.
There are end users and software development companies.
If you are a software development company, and you have professional software engineers, you need to add your own functions to the simple fingerprint software, you just need an SDK. The API/SDK of Huifan Fingerprint is free for you, you can integrate it in the SDK according to your needs.
Also if you are an end user and need to integrate a good software to use directly, Huifan fingerprint software can also support, our fingerprint software can be used directly, no need to develop.

3. How to divide the fingerprint system into user groups?

  1. What is the age group for fingerprint registration?
  • Children and elderly people
In Pakistan, newborn babies do not have ID cards and the government does not have complete control over the data of people. There is no guarantee that all newborns are registered for vaccines, which has led to the death of babies. The HF7000 fingerprint scanner and the Pakistani government worked together to develop a successful case of registration with the baby's toes, ensuring that all babies were registered for the vaccine and grew up healthy.
Similarly, in the Nigerian government election campaign, some elderly people can't sign or vote by name because they can't read or write, so it's impossible to ensure that every citizen can achieve their legal rights.

2. What kind of work do they do?

Government workers, company attendance officers, national data protection agencies

4. Do the fingerprint scanner devices require additional special certification or features?

Many government programs require fingerprint scanners to be FBI certified, or FIPS certified.
Not all fingerprint scanners need FBI certification, but the fingerprint scanner with FBI certification, its fingerprint acquisition picture, fingerprint direction, fingerprint template are all verified, which can protect citizens' data security, which is the reason why Huifan fingerprint scanner has participated in many national bidding projects, our fingerprint scanner will be sent to FBI for certification when it comes to the market. This is why Huifan has participated in many national bidding projects.

5. Is spoofing detection required?

Another common feature is spoofing, also known as live detection, which is a direction you should look at if you are certified or registered with a dedicated administrator. If it is a public place, and you need to ensure the authenticity of the verification, then live verification is a direction you should consider.

6. how much to buy a fingerprint equipment budget

Most government bidding projects and end-users prioritize budget, and many biometric projects fail because the budget for the bidding project cannot be met.
Less than $100
More than $100 USD
7. Humidity
 Usually we have to wipe our fingers away before registering, why is that? High humidity can leave the finger in a wet and saturated state, a state in which we cannot capture an accurate fingerprint image.. It may also cause device problems. To prevent loss of accuracy, choose a fingerprint reader that is ruggedly constructed and can withstand high humidity.

8. Temperature

Low temperature
Cold environments run the risk of exposing the subject's skin and may also cause operational problems with the capture device. Biometric devices should be designed to withstand prolonged exposure to extremely cold temperatures. Fingers can become stiff in colder temperatures, which may affect the quality of fingerprint capture, as high-quality prints require pliable skin. However, studies have shown that fingerprint sensors have good usability in cold environments, as the time spent removing gloves and using the scanner is roughly equivalent to the time spent with bare skin retrieval and using car keys. For this case, registration can be done indoors.

Infrastructure assessment

The environment in which the biometric system will be deployed must be considered. For harsh environments such as wet or humid conditions, the system needs to be robust and durable. Therefore, it is important to perform an infrastructure assessment and then select a biometric method. Voice recognition can work in indoor environments or be used to identify individuals over the phone. However, it may not be suitable for use in a rainy environment as the microphone may be damaged.

10. Population size

The modality to be selected also depends on the size of the population. Certain modalities have faster registration and matching than others. For example, palm vein is highly accurate, but it has a huge template size that makes it unsuitable for large populations. On the other hand, fingerprint and iris recognition have relatively small template sizes.

11. Accuracy and Security

Most fingerprint readers use a scanner-based design that takes a picture of your fingerprint for verification purposes. When the print reader tries to find a match, it uses a mathematical template to evaluate the image it has taken and compares the data to the registered person's profile. Having a high quality image is critical to the performance of the fingerprint reader. In many cases, false positives or false positives can be traced back to the resolution of the device.
Sometimes you'll find quality measured in dots per inch, and reading fingerprints should be at least 250 dpi. other times, manufacturers will list accuracy as a false acceptance rate (FAR) or false rejection rate (FRR). These numbers let you know how many consecutive times an unverified individual needs to log in to access the system, and how often people are verified and incorrectly rejected by the system.
However, not all readers use scanner designs. Modern fingerprint readers can utilize a wide range of biometric technologies, from your pulse to the dilation of your pupils. In the fingerprint reader world, silicon touch sensors are a non-optical design that can be a powerful alternative to standard readers. For example, when you are in a cold environment, it may be more difficult to obtain fingerprints using an optical scanner. The combination of optics and glass means that dust, sand, or wear and tear can eventually fail or damage an optical-based reader.

12. Durability

Any time you handle a device that will see repeated physical contact, you must consider how its body will withstand regular use. For higher throughput environments, you will need to be more concerned. Unless the fingerprint reader is completely portable, an all-metal design is usually your best bet. Plastic tends to be harder to clean, attracts fingerprints more easily, and is not particularly robust.
Usability depends largely on the device's FRR, in contrast to how easy it is to link to the software you want to lock. To sign in to a Windows device, it's best to look for a device that supports Windows Hello. If you've never heard of it, Windows Hello is the software suite responsible for helping users control access to features and programs through biometrics. While support for Windows Hello is not absolutely necessary, it does make setting up a fingerprint reader easier. 

13. Compatibility

You should be confident that the scanner you select will be compatible with any computer operating system you use and the network architecture of any software you want to use it with. Just because a scanner says it supports Windows does not mean it supports all versions of Windows, or that it supports all versions equally. You must be aware of the version-by-version support and see if that support continues on any older operating systems you may be using

How to choose the right biometric fingerprint machine time and attendance system?

A smarter workplace is a hallmark of our technological age. With increasingly new mechanisms in place to make employee management easier and smoother, it's no surprise that most workplaces are turning to biometric attendance. The system has multiple uses - allowing access to premises, registering attendance, improving productivity, and increasing accountability for all stakeholders. Therefore, it becomes important to choose the right type of system to ensure you get everything you need.
Top 5 factors to look at

1. Type of security

The first thing you need to look at is the type of biometric recognition you want. Do you just need a biometric fingerprint scanner? Or do you need a fingerprint and retina scanner? Or do you want fingerprints and a PIN as credentials? If you have a smaller office with limited sensitive data stored inside, then a simple fingerprint scanner will suffice. However, for larger workplaces that handle sensitive data or projects, such as bank vaults or government research buildings, a more advanced system is more sensible

Storage Capacity

A biometric fingerprint system can store a certain number of fingerprints or other biometric information. Whether it's 10 fingerprints or 1,000 fingerprints, understand your needs first. If you are adding more and more employees to your workplace every few months and you want to keep the same biometric access control system installed for years to come, you will need to consider a system that can store more fingerprints. Otherwise, you may have to invest in a new one later or compromise on security.

3. Check the durability features

You don't want the fingerprint sensor to show some fingernail scratches from time to time, do you? Choose a biometric system with durable features, such as dust and scratch-resistant sensors and built-in water resistance. This ensures that your security and technology investment stays with you for a longer period of time.

4. Biometric time

You don't want a long line of employees at the door simply because it takes a long time for the fingerprint scanner to identify an employee's fingerprint, right? Check that the fingerprint/retina scanner scans, identifies and grants/denies access to the biometric system in milliseconds to ensure proper operation. Otherwise, employees will have to come in early and expect to wait outside for their fingerprints to be scanned, resulting in annoyed employees.

5. Easy Integration

One of the most common uses of biometric attendance registration systems is to use employee access information to determine their overtime and absences. When integrated into an employee payroll system, a biometric system can help HR departments easily know what wages or salaries are owed to employees. In addition, it is an unbiased recorder of employee hours worked.
Legal Issues
There are important legal issues associated with the use of biometrics, such as privacy, reliability and remedies. Users may be concerned about the misuse of their biometric samples or the use of the samples for purposes other than their intended purpose. People often consider fingerprints to be trustworthy because they are familiar, but may be skeptical of voice recognition.
