Description

Technical Field

[0001] The present invention relates to the field of intelligent POS terminals, and in particular to an intelligent POS terminal for mobile payment. Background Art

[0002] POS stands for Point of Sale Information Management System. It is a terminal reader equipped with barcode or OCR code technology, and has cash or barter quota cashier function. Its main task is to provide data services and management functions for commodity and media transactions, and to conduct non-cash settlement. POS is a multi-functional terminal. When it is installed in the credit card's special merchants and acceptance outlets and connected to the computer network, it can realize automatic electronic fund transfer. It has functions such as supporting consumption, pre-authorization, balance inquiry and transfer, and is safe, fast and reliable to use. The POS machine reads the cardholder's magnetic stripe information on the bank card through the card reader. The POS operator enters the transaction amount, and the cardholder enters personal identification information (i.e. password). The POS sends this information to the issuing bank system through the UnionPay Center to complete the online transaction, give information on success or failure, and print the corresponding receipt. The application of POS realizes the online consumption of bank cards such as credit cards and debit cards, ensures the safety, speed and accuracy of transactions, avoids the complicated labor of manual blacklist query and order suppression, and improves work efficiency.

[0003] The existing smart POS machines for mobile payment have magnetic stripe card readers that are always exposed to the outside and have no corresponding protective devices, which makes it easy for dust and debris to accumulate on the magnetic stripe card readers when not in use. The dust and debris will be blocked in the magnetic stripe card readers, which will affect the magnetic stripe card readers from reading magnetic cards, and ultimately affect the normal use of the POS machines. Summary of the invention

[0004] In view of the problems existing in the prior art, the purpose of the present invention is to provide an intelligent POS terminal for mobile payment, which can protect the magnetic stripe card reader by setting a protective structure, thereby preventing dust and debris from accumulating and clogging the magnetic stripe card reader and affecting the normal reading of the magnetic card. By setting an installation structure, a rotating structure and a pushing spring, which cooperate with each other, the protective structure can be easily fixed, thereby avoiding unnecessary shaking of the protective structure. By setting a pushing spring, the rotating structure can be easily pushed inward, so that the fixed card block on the rotating structure is inserted into the No. 1 fixed card slot. By setting a movable pressure plate and a drag-reducing ball, the friction force generated by the pushing spring squeezing the rotating structure can be reduced, thereby ultimately making the rotation of the rotating structure and the protective structure easier.
