Compared with manual attendance methods and time clocks, they are more efficient, accurate, timely, and more automated. It also saves a lot of manpower. However, they usually need to set dedicated attendance equipment or instruments to collect attendance data in a centralized location. Not only dedicated attendance hardware devices are needed, but special personnel are required to keep and maintain these devices. In the peak period of work and commuting, employees may also queue up for punching attendance and credit card attendance, which affects the effective working hours of employees. At the same time, there are deficiencies and defects such as time stamps, magnetic cards and IC cards. The fingerprint attendance method utilizes the uniqueness and exclusivity of human fingerprints to realize attendance management. However, modern fingerprint technology has not yet fully matured, and there are still situations where rejection and misrecognition are limited. Application occasions are also limited, and the fingerprint attendance method needs to be expensive. Fingerprint recognition hardware devices, while fingerprint attendance methods need to manage a larger fingerprint database to record legitimate user's fingerprint data. Face recognition attendance methods and voice recognition methods also have similar problems with fingerprint attendance methods, and they are technically immature and large-scale applications will take some time.

One of the biggest deficiencies of the aforementioned types is that they usually require dedicated personnel or specialized equipment to concentrate on one or several locations for attendance, and they can only record employee commute time and time during work hours. Other Zibo electric drums can't make dynamic, real-time and objective records of the employees' more detailed working status data in the unit.

Point in 2005, but it should be the entire time period that employees work. The smart card-based distributed attendance management system can effectively meet the above requirements. Each employee is issued with a smart card. The employee uses a smart card to automatically complete the attendance at his or her job and accurately and timely records various dynamic attendance data during the employee's work. It is especially suitable for software enterprises with high degree of automation and large computer usage.

It provides symmetric and asymmetric encryption functions, including a secure file system that can store X1509 digital certificates, keys, and other related user private information. The Zibo Drum Motor can be provided to enterprises, institutions, and companies with effective and simplified configuration. Safe and convenient user authentication reduces costs. If a portable device that integrates a smart card with a smart key and a smart card reader/writer that uses an electronic key as an interface is used, it will be more convenient to use. Most computers now have a USB interface. The electronic key is compact, flexible, plug-and-play, hot-swappable, built-in PIN protection, and multiple misoperations. It is both highly secure and easy to use. Using this type of smart card in the attendance management system will bring great convenience to the implementation of the distributed attendance system. Only need to deploy the corresponding software in each client, and give the user the appropriate smart card can be distributed, real-time, dynamic employee attendance information collection. The smart card itself can be used for multiple purposes. This eliminates the need for dedicated attendance devices for collecting attendance information.

The contents of the files saved in the smart card are rewritable and freely customizable within the capacity range. According to the actual application needs of enterprises and institutions, companies can selectively record different types of content and can easily expand.

Titanium Dioxide

Titanium Dioxide is white powder, non-toxic, chemically inative, surface treated with aluminum compounds.

The products show good whiteness,high gloss,great hiding power,strong tinting power,favorable weatherability, high chalk resistance,low oil absorption,good wetting and are easy to disperse in a variety of systems.

1)In paint industry, It is used as white pigment and glaze of porcelain.

2)It can also be used as coating and filling in paper-making industry to help paper to be printable and opaque.

3)In metallurgical industry, it can be used to make spongy titanium, alloy of titanium and iron and hard alloy, etc.

4)It can also be used to make nonconductor, electric welding rod and porcelain enamel.

5)It can also be used in synthetic fiber, plastic, rubber, printing, dying, cosmetics, medicine fillings and food additives.
