What is the Definition for Magnetic Stripe Card Reader?
The magnetic card reader only read the data information of the magnetic card one or two tracks via brushing the magnetic card, does not store data, and does not write data. The magnetic card card reader itself is very safe and regular, does not have any bad effect, and cannot be Criminals use criminals to steal bank cards.
First of all, it is necessary to understand what is a magnetic card. The magnetic stripe card is a PVC card coated with a layer of magnetic particulate material. People need to use the recording head to express certain information when inputting information into the magnetic card, then store it in the track and read it. When taking it, it is also read by means of a recording spur. In fact, the working principle of the magnetic card is like the working principle of the tape of the recorder.
Magnetic card card reader , it has three main interface, USB interface, serial port RS232 interface, keyboard port PS2 interface, usually USB interface and serial port RS232 interface use more convenient,more extensive. The following mainly introduces the performance characteristics of the USB interface and the serial port RS232 interface magnetic card reader.
USB interface magnetic card reader supports plug and play, hot swap, customers do not need secondary development, access to the corresponding system can be used directly. The magnetic card supporting the international standard goods organization ISO standard and AAMVA standard , does not need to be separately connected to the power supply. The USB interface serves as both communication and power supply, the USB interface magnetic card reader is very convenient and simple to use.
What is the working principle of the USB interface magnetic card reader? The reading of the data on the magnetic stripe card is directly performed by the magnetic head, the internal circuit board decoding IC of the card reader is decoded by the F2F hardware, and then the magnetic card data is uploaded through the USB interface IC. USB magnetic card reader adopts USB2.0 transmission technology and has fast transmission speed.
The magnetic card reader of the serial port RS232 interface is the main feature. It can send and receive commands from/to the computer or the industrial control host. It can be programmed, which is relatively complicated. It isnot plug and play type. The application industry and scope are also very wide. Now main Applicable to the in-vehicle system, reading the American driver's license.
