Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other under the premise of creative work is not made
Embodiment, belong to the scope of protection of the invention.
With reference to figure 3, Fig. 3 is a kind of method of head position for obtaining point-of-sale terminal POS provided in an embodiment of the present invention
Flow chart.As shown in figure 3, the head position of the POS includes first position, the second place, the first position corresponds to magnetic
The first magnetic track and the second magnetic track of bar card, the second place corresponds to the second magnetic track and the 3rd magnetic track of the magnetic stripe card, described
Method comprises the following steps：
Step 301, it is determined whether the head position of the POS can be obtained；
Specifically, with reference to shown in figure 1, the first magnetic track is track1, the second magnetic track is track2, the 3rd magnetic track is
Track3, in user's brush magnetic stripe card, judge head position from reading in record, and obtain the head position of the POS.
Step 302, in the case of it is determined that failing to obtain the head position of the POS, decoded by the self study
Method obtains the data of the magnetic stripe card；
Specifically, the data that the magnetic stripe card is obtained by the self study coding/decoding method, including：
First magnetic track is decoded by the first track data form direct decoding method, and passes through the second track data
Form direct decoding method decodes to second magnetic track；Or
First magnetic track is decoded by the first track data form inversely decoding method, and passes through the second track data

Trial decode original brushing card data.
The forward direction is swiped the card and reversely swiped the card as relative direction of swiping the card, it is assumed that magnetic stripe card relative head is from left-hand when swiping the card
The right side is swiped through to swipe the card for forward direction, then it is reversely to swipe the card that magnetic stripe card relative head is swiped through from right to left when swiping the card.The set form solution
Code, according to the original track data for acquisition of swiping the card, decoded using corresponding track format, such as to the first magnetic track initial data,
Decoded using the first track data form, to the second magnetic track initial data, decoded using the second track data form, to the 3rd magnetic
Road initial data, decoded using the 3rd track data form.
Step 303, if obtaining the data of the magnetic stripe card by the self study coding/decoding method, judge that two magnetic tracks are
It is no to have data；
Specifically, assume that track1 data format direct decoding methods and track2 data format direct decodings can be passed through
Method obtains the data of the magnetic stripe card, then illustrates the first magnetic track corresponding to the head position of the POS and the second magnetic track, obtain
Take the data of first magnetic track and second magnetic track.
Step 304, if described two magnetic tracks there are data, the result of swiping the card of the magnetic stripe card is obtained, and described in record
The head position of POS；
If only a magnetic track there are data, the result of swiping the card of the magnetic stripe card is obtained.
If, can be according to the data of 2 magnetic tracks specifically, first magnetic track and second magnetic track have data
The position of magnetic head installation is identified, and the position that the magnetic head is installed is recorded in card reader, when subsequently swiping the card, according to having known
Other head position, is decoded using set form.
For example, after self study mode successfully decoded, if brushing card data is track1, track2 data, illustrate that magnetic head is pacified
Mounted in first position；If brushing card data is track2, track3 data, illustrate that magnetic head is arranged on the second place.Judge magnetic head
After installation site, designated area inside POS is recorded in using magnetic head installation site as mark.Original state MAG_FLAG is 0,
Expression does not determine head position；If it is determined that MAG_FLAG is then arranged to 1 by magnetic head installed in first position；If it is determined that magnetic head
MAG_FLAG is then arranged to 2 installed in the second place.
Set form decodes：For in the case of it is determined that the head position of the POS can be obtained, obtaining the POS
The information of the head position of machine, the information of the head position of the POS include the information or described second of the first position
The information of position；
If the information of the head position of the POS is the information of first position, pass through the first track data lattice
