Method and device for obtaining magnetic head position of point-of-sale (POS) terminal

Abstract

The invention provides a method and device for obtaining the magnetic head position of a point-of-sale (POS) terminal. The method is characterized by determining whether the magnetic head position of the POS terminal can be obtained; when determining that the magnetic head position of the POS terminal cannot be obtained, obtaining data of a magnetic stripe card through a self-learning decoding method; and if obtaining the data of the magnetic stripe card through the self-learning decoding method, and if two magnetic tracks ( a first magnetic track and a second magnetic track or the second magnetic track and a third magnetic track) both have data, obtaining a card swiping result of the magnetic stripe card and recording the magnetic head position of a magnetic head of the POS terminal. Through the two-track magnetic head self-adaption method, the magnetic head installation position can be positioned automatically according to the card swiping result, and thus the problem that two different programs are needed due to different installation positions of the two-track magnetic head is solved, production complexity is simplified, and production efficiency is extremely improved.

Description

technical field [0001] The invention relates to the field of POS machines, in particular to a method and equipment for acquiring the position of a magnetic head of a sales terminal POS machine. Background technique [0002] The traditional financial sales terminal (point of sale, POS) magnetic stripe card reader uses a 3-track magnetic head, which can read the three magnetic track information track1, track2, and track3 of the magnetic card at one time. track1 generally exists in the credit card, and records information such as the cardholder's name; track2 records the main account number; track3 belongs to the card issuer's custom area, which can record transaction records or amounts. [0003] But for low-cost simple POS, such as mobile phone card reader Lakala, Square, etc., use 2-track magnetic heads, which can only selectively read track1, track2 or track2, track3. According to the difference of domestic and foreign financial environments, the installation position of th...

AI Technical Summary

Problems solved by technology

It is very inconvenient to use two different programs just because the installation position of the magnetic head is different, and often because the installation position of the magnetic head does not match the programming program, the card cannot be swiped, resulting in batch rework of the product, which greatly wastes manpower Material resources, reducing production efficiency
