Embodiment Construction
[0086] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the present invention, and are not intended to limit the present invention.
[0087] like Figure 1 to Figure 2 As shown, this embodiment provides a magnetic stripe card card swiping terminal decoding method, the magnetic stripe card is provided with a magnetic card chip, the card reader terminal is provided with a processor; the decoding method includes,
[0088] S1, when swiping the card, the magnetic card chip is connected to the processor, and it is judged whether an interruption occurs in the processor monitoring; if so, the processor turns off the interruption, turns on the timeout timer and executes step S2; if not, exits the interruption;
[0089] S2, updating the ...

The invention discloses a decoding method for a magnetic stripe card swiping terminal. A magnetic card chip is arranged in the magnetic stripe card, and a processor is arranged in the card swiping terminal; the decoding method includes: S1, when swiping a card, the magnetic card chip Be connected with described processor, judge whether processor monitors to interrupt; If so, then processor closes interrupt, opens overtime timing and executes step S2; If not, then exits interrupt; S2, update timing count; S3, described processor Read the level status of the three external IOs to determine whether any IO has a level transition. If so, record the time interval between the IO that has a level transition and the last transition of the IO to the array corresponding to the IO , each of the IOs corresponds to a track, and each track corresponds to a T array, and S4 is executed; if not, S4 is directly executed; and other steps. The advantages are: the success rate of decoding is increased, the probability of reporting bit errors is reduced, the design cost is reduced, and the user experience is improved.
Description
technical field [0001] The invention relates to the fields of electronic communication and financial payment, in particular to a decoding method for a magnetic stripe card swiping terminal. Background technique [0002] In daily life, magnetic stripe cards are used as information recording carriers, which are low-cost, high-strength, easy to carry, stable and reliable. It is widely used in various bank cards, gift cards, transportation cards and other fields. As a card reading device, the financial terminal can read magnetic stripe cards. But with the wide application, it also brings some problems. For example, after using our magnetic stripe card for a period of time, the recognition rate decreases due to wear and tear; the user's card swiping speed is inconsistent, and the front and back swiping habits are different, making it difficult for the magnetic card to be read by the device; in order to ensure the card reading rate in the design Many software and hardware funct...
