Many POS users will respond to us after using the pos machine for a period of time. Sometimes, when you swipe your card, you will always hear the "swipe error, please re-brush" prompt. Today, Xiaobian will explain the reason and solve the POS machine error. The method is arranged for everyone, I hope that everyone will reduce such things in the process of using the POS machine in the future.
1 head has a booty
This problem usually occurs on the POS body that has been used for a while, because the use of dust-like debris covers the head of the POS machine for a long time, so that the magnetic strip of the card body cannot be well and the head when the card is swiped. Contact caused a swipe error. For this reason, we recommend that you use a piece of hard paper with a moderate hardness and gently drag it horizontally and longitudinally in the card slot to wipe off the dirt on the head.
2 magnetic card fouling or demagnetization
This reason does not have much to do with the POS machine. The problem occurs on the cardholder's card. Some people usually do not pay attention to maintaining their bank card, so that the card magnetic strip is contaminated with stolen goods, so that the POS machine cannot read the full card when swiping the card. The magnetic stripe information on the top causes the card to fail. The demagnetization is because the high-frequency electromagnetic wave generated by the mobile phone in the working state will magnetize the bank card magnetic strip, so that the information recorded by the magnetic strip will be disordered, and naturally the card will not be stuck. The solution to the problem is to use a soft paper to erase the dirt on the magnetic surface of the magnetic card. If the magnetic card is demagnetized or the magnetic card itself is faulty, it is recommended to replace the magnetic card with the issuing bank.
3 way to swipe the card is wrong
This problem is generally eager for POS users, may not see the front and back of the card or brush too fast, such an operation will also lead to card error. The solution is very simple, the card should pay attention to the direction of the magnetic surface, and the speed of the card is basically uniform.
