Smart cards can be roughly classified into two categories: ID and IC cards; different cards can be selected according to different functional requirements. The electricity of the intelligent read-write IC card is partially composed of an antenna and a control part CPU (in a PVC package). The antenna of the card is only a few sets of winding coils are packaged in the card, there is a high-speed (106KB baud rate) interface in the card, and 16 control unit readers sends a set of electromagnetic waves with a fixed frequency to the card. An LC series resonant circuit, the frequency of which is the same as the frequency emitted by the reader, is excited by an electromagnetic wave, and the LC resonant circuit resonates so that there is a charge in the capacitor. At the other end of the capacitor, a unidirectional conduction pump is connected to store the charge in the capacitor to another capacitor. When the accumulated charge reaches a certain voltage, the capacitor can be used as a power source to provide work for other circuits. Voltage, transmit the card data or access the reader data.
The IC/ID card used in the smart card management system is a contactless smart card. According to the different permissions and functions of the card in the system, the card can be divided into the following categories:
The system authorization card system authorization card is provided by the system manufacturer, is issued with the wing gate management system, and has the highest authority in the system for the senior management personnel to enter the system for login and use. After using the system authorization card to enter the system, all functions such as system parameter setting and system initialization can be performed, and an operation card can be issued at the same time.
The system operation card system operation card is a credential for the general manager to operate the system and can perform the authorized functions and manage the daily work of the system.
Employee cards are used by ordinary people and are used by ordinary people to turn on smart wing gates, perform attendance, or eat in the cafeteria.

Wing gate smart card types explain
Due to the rapid development of science and technology, wing gate smart gates have begun to use ID card IC cards for inspection. In order to keep pace with the times, we must understand the facts. How to choose wing card smart card it! The following small series to explain the details of the wing gate smart card. So that customers can use inspection channels.
