Card lock design: a combination of natural and comfortable material, texture beautiful, feel good patent drop-cast structure lock cover, smooth and beautiful appearance, easy to operate and efficient dust, strong light full protection design; innovative surround sound and light tips and more convenient , more humane; apply to hotels, commercial and residential buildings, offices and other occasions. Magnetic Lock Features: High-quality American standard five round cylinder, less noise, durable. Mechanical lock sets using picture-bead structure, technology turned difficult. Using an independent motor-clutch design. To prevent damage to the handle and damage internal structure of the door. Precision integrated steel craft, lock body surface without screws exposed, anti-destructive excellent. Higher safety performance: T5557 card lock the card data using three-layer encryption mechanism, data security has been high, but after all, just to keep the card data encryption software. The Mifare 1 card reader when the reader with the use of three between the two-way authentication mechanism to verify the legality of the use of each other, and in the communication process all the data are encrypted transmission, and a replay attack protection; addition, each card partition has its own independent access mechanism and two 6-byte read and write passwords, security card data has been more reliable content protection [product] performance specifications for battery-wave sensor technology, sensor more sensitive; circuit Banzhu chip: Texas Instruments TI chip; Power supply: four on the 5th (6 7) alkaline batteries; Static power consumption: <30μA; dynamic power consumption: about 200mA; Low Voltage Tip: 5V; sensing distance: 3 -5CM; Suitable temperature: -20 ℃ ~ 50 ℃; Relative humidity: 15,000V, under strong static interference still ensure that information is not lost, job stability. Package: A package of 10 sets of locks carton weight: no mechanical contact between the 3-3.5KG high reliability Mifare-1 card reader, avoiding the various failures arising due to exposure to reading and writing. For example: As brutal card and non card insertion of foreign objects, dust or oil resulting in poor contact and other causes of failure. In addition, Mifare-1 card surface without bare chip, chip off without fear, electrostatic breakdown, leaving the card failure bending damage and other issues, both for card printing, design, packaging and advertising Vision
