When the cardholder passes the card to the access control microprocessor when the card is swiped at the card reader:
1 to identify and judge;
2 Invalid cards will be ignored. If the card is not registered, there will be no effect when the card is swiped. At the same time, if the wing gate is not legally ordered, the gate will not be opened, playing the role of access control;
3 card registration authorization, is a valid card, through the W26 or W34 signal processing, identification of the legitimacy of the card, read the card's serial number, through the access control microprocessor, recorded the current credit card time, card number and other related information, and access control The microprocessor transmits information or pulse signals to the wing gates, and the gates are open to facilitate the passage of the card holders. As for which mode of use, the setting of the gate microprocessor is considered.
Access control and wing gates are mutually compatible and inseparable components. The perfect combination of the two can achieve channel management, avoid human emotion cards, eliminate entry of bad people, improve work efficiency, and save costs.
Medicine Raw Material is related pharmaceutical industry. We mainly supply two items, one is Sulfanilic Acid, another is Formic Acid, with our high and stable quality, can produce high and stable quality of bulk pharmacetuical chemicals.
Pharmaceutical raw materials encompass elements that are required to manufacture a variety of different drugs. These materials are derived and extracted from sources that could be natural or synthetic. Every pharmaceutical is made up of active ingredients .
Pharmaceutical industry has a lot of constraints and specialties which make it stand on a completely different scale than any other industries. Being closely related to the medical field and also complementary to it, the pharmaceutical industry needs utmost care and precision in each and every aspect of the field ranging from collecting the raw materials to getting the final product ready for supply in the market. ï‚ž Let us get into a few details about the pharmaceutical raw materials and find out some important and interesting facts about them.
We mainly supply Sulfanilic acid & Formic Acid , which are used as raw material for Pharmaceutical industry.
