After reading an article by Bai Yansong, if any unit starts to emphasize attendance and punch cards, it must be the time for it to go downhill. It seems that the company is the rhythm of no zuo no die.
With the company's increasingly rigorous attendance system, choosing a suitable fingerprint attendance machine is also necessary. In view of the visibility of the effective office brand, he purchased a deli brand fingerprinting machine. After a period of use, he is now sharing his experience in using it.
UnpackingSimple packaging, product features introduced outside the box are reflected
Open the packing box, and the fingerprint machine is embedded in the middle of the sponge protection layer, which plays a good role in buffering during the shock during transportation. The upper left of the fingerprint machine is a TFT color screen, which shows a clear display. The lower left is a 4*4 plastic keyboard. The arrangement is neat, simple and clear. The upper right is a voice player. The following is the fingerprint collection area. Body size is 181mm*37mm*131mm

Power adapter, DC 5V power supply, power cord is also a long distance is not a problem

The environmental protection statement is very strong in environmental awareness. Now that this is hazy, the awareness of environmental protection should be worthy of our attention and attention by every company.
Take a look at the display first, using a 2.4-inch TFT color screen, a layer of plastic protective film on the surface to prevent scratches on the screen, surrounded by a black border, compared to the phone's borderless design, this border is really a bit wide, ah, the screen display resolution Not particularly high, but it's good enough for a fingerprint machine. The gap between the screen protection film and the fingerprint box is a bit large and it is easy to accumulate dust.
The voice player is located directly above the fingerprint collection area and has voice output function, real voice, which is very intelligent
Key area, silver and white plastic keyboard arrangement is very regular, the keys are very light, there is no loose feeling, rebound is also very full force, the keys are not backlit keys, the eyes of the dark is not easy to identify, time is also easy to wear the surface of the word. 0-9 Arabic numerals and 26 English letters, numbers, Chinese, English, and free spelling; ESC is used when exiting or canceling; MENU menu key; OK confirms the current setting item; move up and down keys and # switch key.
The fingerprint identification area is a circular recessed part, which can effectively prevent the collection area from being picked up. The fingerprint collection area is a square transparent area and will light up after plugging in.
Fingerprint recognition reaction speed is still very fast, 32-bit fingerprint recognition chip can recognize the success of a few seconds, and is a 360-degree no-fingerprint fingerprint collection, especially for children's shoes come to work, fingerprint recognition rate is high, basically A success. Compared with the previous company's use of a brand of fingerprint machine, the recognition rate is quite low, press 3-5 times to get fingerprints, and must be placed in the fingerprint collection center location, fingerprint texture is not very clear, but also to identify up to ten times the above.
Fingerprint storage capacity, can hold up to 1000 fingerprints, recording capacity is up to 200,000
The rear panel triangles are attached to the wall with the use of expansion screws to increase the stability of the suspension.
Interface: 1, DC5V DC power supply interface 2, USB interface, no online operation, only a USB storage media, download fingerprint information is very convenient, the system upgrade also only need to upgrade the system to the USB flash drive to upgrade; 3, The COM network interface can share attendance information with multiple computers and can also communicate settings.
The first thing that comes into view is the deli's LOGO (advertising, so the common problem of the software platform), and then enter the time interface
The administrator recognizes the fingerprint, enters the main menu settings, and then performs department setting, shift setting, user management, attendance statistics, advanced settings, and information query settings. It looks very tedious.
In the "User Management" menu's <Registered User>, new users are added and fingerprints are entered. Each user can enter 3 fingerprints to avoid signing due to a single finger injury.
Attendance statistics and download: plug in the USB storage device, find the attendance statistics, click OK to download the required attendance information to the storage medium for viewing in the computer.
Attendance information includes attendance sheet, abnormal attendance statistics sheet, employee credit card record sheet, and employee information. Excel sheets are automatically generated for easy viewing.
Look at the employee's credit card record form again. The date, time, and order of the cards are neat and easy to view and count.
Unusual attendance statistics are clearly marked. Late arrivals, early retirements, and total time are on the list.
After more than a month of use, the overall impression of this fingerprint machine is still good, it is easy to operate, fingerprint recognition efficiency is also very high, the built-in statistics table, download view is very convenient, attendance check cycle can also be free to choose, The voice announcement function is even more aware of whether or not you are late and leave early. In view of the small number and concentration of companies, the communication function is basically not used.
to sum upadvantage:
1, the appearance of simple and stylish; 2, easy to operate, store a wide range of information; 3, fingerprint recognition speed, a single user can collect multiple fingerprint information
4, support for multi-machine networking, resource sharing; 5, off-line operation, you can download attendance information without connecting a computer; 6, system upgrade is convenient; 7, attendance information is clear, easy to query;
Disadvantages:
1. The content is too cumbersome; 2. The fingerprint recognition effect is generally cold weather; 3. If the fingerprint can be controlled by the fingerprint switch, it is better; 4. The intelligence needs to be improved.
Voltage: The voltage of the lead-acid battery is usually 12V or 24V and other standard voltage values.
Capacity: Capacity is an important indicator to measure the storage capacity of lead-acid batteries, usually expressed in ampere-hours (Ah). The capacity of different lead-acid batteries varies. Users can choose the appropriate capacity according to actual requirements.
Weight and size: The weight and size of lead-acid batteries vary by model and capacity. In general, the larger the capacity of the lead-acid battery, the greater the weight and size.
5. Development Trend
Performance improvement: With the continuous progress of technology, the performance of lead-acid batteries will be further improved, including improving energy density, extending service life, and reducing self-discharge rate.
Environmental requirements: With the enhancement of environmental awareness and the improvement of regulations, the environmental requirements for lead-acid batteries are becoming higher and higher. In the future, lead-acid batteries will pay more attention to the application of environmentally friendly materials and the recycling of waste batteries.
Intelligent development: Intelligence is one of the important development directions of the battery industry. In the future, lead-acid batteries will pay more attention to the application of intelligent technology, such as intelligent charging, intelligent monitoring and other functions will improve the efficiency and safety of the battery.
To sum up, Lead Acid Battery, as a traditional chemical battery, has the characteristics of low cost, mature technology and easy maintenance, and has been widely used in many fields. With the continuous progress of technology and the improvement of environmental protection requirements, the performance and environmental protection of lead-acid batteries will be further improved.
