Problems solved by technology
[0004] The use of the above-mentioned various types of information cards makes it difficult to integrate the system. The current situation is that many so-called one-card systems require users to use multiple cards, which makes the convenience and flexibility of the system very flawed.

Embodiment Construction
[0023] The present invention will be further described below in conjunction with accompanying drawing:
[0024] Such as figure 1 As shown, the structure of the card reader involved in the present invention is: the front end is an induction module 1 and an induction module 2, such as an induction coil and a scanning head, and these two parts can be integrated into one. The sensing module is connected to the intelligent conversion module 3, and the intelligent conversion module 3 can convert electrical signals, magnetic signals and optical signals into digital information. The intelligent conversion module 3 is connected to the central processing unit 4. After the central processing unit 4 performs error correction, processing and encoding on the converted digital information, the information is transmitted to the card reader controller through the input / output module 5, and the card reader The controller makes a judgment and outputs an instruction to execute a predetermined op...

The invention provides an integral card reader capable of reading and writing various types of IC card and strip code card and its reading / writing method. The card reader has one or more sensing antenna, and simultaneously contains a strip code reader, a central processing unit and an input / output module. The card reader reads card information or strip code information via the sensing antennas and a strip code card reader respectively or simultaneously to send information to the central processing unit; the central processing unit identifies the information and then perform error correction, processing and encoding on the information; then the information is sent to a card reader controller via the input / output module, and the card reader controller performs authority judge on the information by combining with pre-stored user information authority setting to provide authority for authenticated information and send information for executing a preset operation.
Description
technical field [0001] The invention relates to a card reader, in particular to a card reader capable of reading and writing various types of information cards and a reading and writing method thereof. The readable and writable information cards may be readable and writable smart cards (magnetic stripe cards, IC card or ID card), or a barcode card. Background technique [0002] With the rapid development of information technology, more and more card readers are applied to various occasions. Inductive card readers are mainly used to identify, read, write and send compiled information devices. Smart cards (magnetic stripe cards, IC cards or ID cards) are used in the system. The barcode recognition uses the recognition mode of scanning the card, using the barcode card. [0003] At present, these two modes are widely used, but they are not compatible with each other, that is, a system using smart cards cannot recognize barcode cards, and vice versa. This makes the existing al...
