Description

Contactless Card Lead / Light System {CONTACTLESS TYPE CARD READ / WRITE SYSTEM}

The present invention relates to a contactless card read / write system, and more particularly, to recognize information recorded on a radio frequency ID card as a contactless (radio frequency), and to judge and control the recognized information to output the determined controlled information. In addition, the present invention relates to a contactless card read / write system capable of recording the controlled information on an ID card.

In general, a card reader has a card contact type and a contactless type. In the case of the card contact type, a magnetic card, such as a credit card or a cash withdrawal card, reads magnetic information by contacting a card with a card reader. For example, information on a card is read using an optical signal or a frequency signal such as a barcode or an RF-ID card.

However, the card reader system that reads the information of the card, whether contact or contactless, simply reads the information and sends the read information to the central controller, and the central controller controls the information of the card to read the card information. To be recognized.

In this way, the conventional card reader simply reads the ID card information by contact or non-contact, and inputs and outputs it by the control signal of the central control unit, and reads the ID card information by itself and reads the read information. There was no function for recognizing, judging, controlling, and writing the controlled information back to the ID card.

Therefore, since all the information read from the card reader is integrated control processing and management in the central control unit, not only the function and management of the central control unit is complicated, but also has a problem in the control speed and capacity of the central control unit.

In addition, when an error or failure occurs in the central control unit, the entire system cannot be operated.

Accordingly, an object of the present invention is to read information from an ID card in which information is recorded by a card read / write system, and to control and read and control the read information, and to record and manage the controlled data. I want to record on the ID card.

In addition, the present invention is to provide a card lead / write system that can automatically manage the recording and management status controlled by the card lead / write system with a personal computer.
