Brief introduction of access card

Access cards are used in access control systems, such as access cards, access cards, parking cards, membership cards, etc. Before issuing access cards to end users, the available areas and user rights are determined by the system administrator. Users swipe their cards to enter the management area. Users without access cards or permissions are not allowed to enter the management area.

Systematic Review With the strengthening of the consciousness of the ancient enterprise management circle, the ancient management mode based on the utilization of cards and certificates has become less and less common. Bar code cards, magnetic stripe cards and contact ID cards are used as forms of patrol, access control, consumption, parking and club management. , in the intelligent community management to play its own unique role. However, due to the stagnant performance of card management and the limitation of traditional card functions, it is necessary to add more cards to the owners from time to time to meet the needs of property management, such as access cards, production cards, access cards, parking cards and membership cards. This not only increases the management cost, but also increases the difficulty for each business guest to manage everyone's card, and sometimes even "it is a problem to have more cards". Therefore, in the gradual elimination, the mainstream card type of 20000.00000 100005 should belong to IC cards, but the development of CPU cards is also quite rapid, which is a trend. IC card is widely used, on the one hand, it has high security; In addition, it mainly brings convenience to smart cards. For example, Shenzhen Adobe has done a good job on this kind of IC card, which integrates access control, elevator, parking lot, consumption, attendance, patrol and intelligent channel into a system, and can realize the function of smart card without networking.

In the late 1990s, due to the stagnation of contactless card reading technology, ID card technology and communication technology, the access control system has also made progress under the influence of the intelligent trend. The original access control scheme used contactless ID cards, instead of chip cards that can transmit suspicious information without physical contact. The instantaneous energy required for reading and guarding information is supplied by the card reader, and the sensing interval is 10- 15cm, which really hides a card. Compared with the traditional card technology, adoption is a contact ID card technology that can hide the identity, insurance and superstition outside the old intelligent area.
