ID card reader: also called ID card reader, built-in security module of the Ministry of Public Security, you can read ID card number and name photos from the built-in chip of the ID card.
ID card issuer: Connected to the computer, it is used to read the IC card number of the ID card (not the ID card number), and can use the customer's ID card as an ordinary IC card to authorize the access control controller for the access control gate to open the door.
ID card reading head: used on the controller to read the IC card number of the ID card and send the card number to the controller through the Wiegand protocol (standard access control protocol). The controller is responsible for identifying whether it has authority.
Authorization: Refers to the authority to authorize someone (or a card) in the system to access a certain access control device. Authorization adds permission information to the system. Permission information may be stored in the database of the management host, or may be delivered to the device.
Authentication: Authentication refers to the process by which the system determines whether a user has permission to enter or exit when a user swipes a card, barcode, ID card, or fingerprint. Authentication requires two necessary data, one is the authorized information in the system, and the second is the credential information provided by the current user. Authentication is usually done by the access controller or computer host.
Waterproof coatings are necessary to protect water facilities. Water facilities are often exposed to pressurized water. They also need to withstand the constant attacks of multiple elements, and leaks are common after a few years. UMS-AUPT provides a brush-coated Polyurea Waterproof Coating system for liquid applications that provides long-term protection for simple, detailed or complex water installations.
UMS-AUPT brushed polyurea waterproof coating system is widely used in the sealing and waterproofing of concrete water facilities. such as reservoir waterproof coating, Dam Sealer , aqueducts waterproof, water pipes waterproof, Water Tank Sealant, aquariums waterproof and Concrete Pond Sealant.
The advantage of UMS-AUPT brushed polyurea waterproof coating system
1. Can be brushed by hand, rolled, and airless if necessary. Construction is fast and flexible. Sealant for Ponds , it can be painted on any curved surface, inclined surface and vertical surface without sag.
2. No solvent, no VOC emission, environmental protection and energy saving; humidity and temperature have little effect on the construction process.
3. Advantageous physical and chemical properties, such as tensile strength, elongation, flexibility, wear resistance, aging resistance, corrosion resistance, etc.
4. High-strength coating, high elasticity and no seam are top-grade waterproof protective coatings with excellent performance.
5. High adhesion and durability to various substrates such as steel, wood, glass, ceramics and concrete. Does not crack or fall off.
