• How Do Plastic Key Cards Work?

The plastic key card is a type of RFID proximity card, used in the access control system, such as room card, hotel key card, access card, parking card, membership card, etc.,  Before the plastic key card is issued to the end user, it is set by the system administrator to determine the usable area and user rights. The plastic access key card is swiped to enter the management area, and users who have no access control key card, they can not enter the management area.

Because there is a chip called RFID inside, when we pass the card reader with the card containing the RFID chip, the electromagnetic wave emitted by the card reader will start to read the information in the card. It can be read, and it can be written and modified, so the chip card is not only a key, but also an electronic ID card.

• Plastic Key Cards Detailed Description:

With the continuous strengthening of corporate management awareness, management models based on the use of cards are becoming more widespread. Barcode cards, magnetic stripe cards, and ID cards (such as patrol management, access control system, payment, parking, club management, etc.), they have a unique roles outside the management of intelligent communities. 
However, as the card management performance has been stagnant, because the limitations of traditional card functions cannot meet the needs of a one-card, it is necessary to add cards to the owner from time to time to meet the needs of property management, such as access cards, access control cards, parking cards, membership cards, etc., not only increase management costs, but also increase the difficulty for each owner to manage everyone’s cards.
Therefore, rfid ic cards are becoming more and more important after in 2010,  and ID cards are in the phasing out. But the development of CPU card is also very rapid which is a trend. 
IC card has a wide range of applications. On the one hand, it has high security, on the other hand, it brings convenience to the all-in-one card. 
The payment, attendance, patrol, intelligent channel, etc., which are integrated into one system, and the functions of the all-in-one card can be realized without networking.

In the late 1990s, due to the continuous development of contactless card reading technology, ID card technology and communication technology, the access control system has also made progress under the influence of the general trend of intelligence. The original access control plan adopted the non-contact ID card, which is not a kind of a chip card that can realize information transmission without physical contact. The instant energy required to read information is supplied by the card reader. The induction interval of 10-15cm can achieve the effect of one card with multiple uses.
