Pos bank card placement method: if it is a chip card, insert the card directly with an opening, and the screen will prompt. If it is a magnetic stripe card, see which direction the pos machine swipes the card, swipe the card at a uniform speed from top to bottom, and the magnetic stripe faces the head, and the screen will prompt. If you have both a chip and a magnetic stripe, please give priority to the plug-in operation. If the plug-in operation is not good, then choose the card swiping operation.

Precautions:

Pos card swiping machine can swipe any card with UnionPay logo, and normal POS machine can swipe all UnionPay logo cards including credit cards and savings cards. However, some POS machines are specialized in swiping savings cards, so this kind of POS machine can only swipe savings cards, not credit cards.

Where the POS system, MIS system or ERP system is used for enterprise management and financial management, large retail malls, supermarkets, hypermarkets and large chain fast food industries, due to their relatively sound accounting and high investment in system construction, it is not appropriate to replace tax-controlled cash registers. Moreover, tax-controlled cash registers cannot replace enterprise management and financial management. Therefore, the tax control reform should be implemented after the relevant national standards are promulgated.
