Abstract

The invention discloses a magnetic stripe decoding method. The magnetic stripe decoding method comprises the steps of acquiring an original signal and a user decoding mode of a magnetic stripe; decoding original signals through a software decoding mode, wherein the specific process of decoding original signals through the software decoding mode includes carrying out amplitude limiting amplification on the original signal by the PGA at a preset multiple, obtaining amplitude limiting amplification signals, sampling amplitude limiting amplifying signals through ADC, obtaining sampled digital signals, and decoding the digital signals through CPU decoding software program. The digital signals are obtained after the PGA and the ADC, a decoding software program is used for decoding the digital signal, and the decoding process is completed by software. The method has the advantages of high anti-interference capability, high compatibility and high card swiping success rate. The invention further discloses a magnetic strip decoding system.

Description

technical field [0001] The invention relates to the technical field of information identification, in particular to a magnetic stripe decoding method and system. Background technique [0002] Magnetic stripe card is a kind of identification card made of magnetic material. It has a wide range of applications and can be made into bank cards, membership cards, road toll cards and so on. The front side of a general magnetic stripe card is made of polyvinyl chloride, polyester film or composite paper, and its reverse side is pasted with a magnetic strip with one or several magnetic tracks. [0003] The information in the magnetic stripe card must be read and decoded by the magnetic stripe card terminal. Usually, the card terminal is composed of a magnetic head, a decoding system, an encryption and decryption system, and a communication control system. The "circuit realization scheme for realizing multi-mode magnetic strip decoding based on a single module" of the present inventi...
