Embodiment 1

[0046] This embodiment 1 provides a method for reading magnetic card data. The technical scenario implemented in this embodiment may specifically be: the waveform of the magnetic card data read in this embodiment is as follows: figure 2 As shown, among them, figure 2 where a0 represents the distance between the first maximum value and the first minimum value; a1 represents an area with a different sign in the sampling area, a2 indicates another area with a different sign in the sampling area, and a3 indicates the next area with a different sign in the sampling area number area; the method provided in this embodiment is as follows:

[0047] As the magnetic head passes through the area where the polarity changes on the track, the extreme point of the induced current is generated, so the current signal jumps at the critical point. Because of electromagnetic induction, a large number of invalid signals will be generated. These invalid signals must be filtered out first, otherwis...

Abstract

The invention is applied to the electronic payment field, and provides a magnetic card data reading method, an apparatus thereof and a mobile POS machine. The method comprises the following steps: acquiring waveform of magnetic card data; acquiring a distance from a first maximum value to a first minimum value of a waveform signal, and determining a sampling interval according to the distance; extracting a peak value of the waveform signal in the sampling interval with boundary of a first different signal area as reference; if an obtained distance between adjacent peak values is in an interval threshold, adjusting the sampling interval according to the obtained distance between the adjacent peak values, and extracting a peak value of the waveform signal in an adjusted sampling interval with right boundary of a next different signal area as reference; if the obtained distance between the adjacent peak values is not in an interval threshold, extracting the peak value of the waveform signal in the sampling interval with right boundary of a next different signal area as reference; acquiring magnetic card data according to the peak value of the waveform signal. The method in the invention has the advantage of reducing a decoding error rate.

Description

technical field [0001] The invention belongs to the field of electronic payment, in particular to a method and device for reading magnetic card data and a mobile POS machine. Background technique [0002] In recent years, with the maturity of technology and the rapid development of 3G mobile communications, mobile payment relying on high-end mobile Internet and mobile terminals equipped with smart platforms has broken through the limitations of time and space. Due to the limitation of venues and wired communication lines, the application of POS is restricted, such as the payment of public utilities such as water, electricity, gas, shopping consumption at large commodity exhibitions, catering, entertainment venues and other mobile-featured consumption and credit card consumption. In recent years, words such as mobile payment, mobile wallet, and mobile card have appeared frequently. How to realize mobile payment conveniently, without leaving home, and realize various payments ...
