Description

technical field [0001] The present invention relates to electronic payment technology, in particular to a transaction method and system, a point-of-sale terminal and a mobile terminal. Background technique [0002] In the prior art, a user can use a point of sale (POS, Point of Sale) transaction system to complete transactions. Such as figure 1 as shown, figure 1 It is a schematic diagram of the composition structure of the existing POS transaction system. Among them, the POS terminal reads the card information of the transaction card, such as the magnetic track data of the magnetic stripe card or the card number of the integrated circuit (IC, Integrated Circuit) card, etc., sends it to the POS service platform for legality verification, and receives the returned information from the POS service platform. Verification result, if the verification is passed, then continue the subsequent processing, otherwise, end the transaction; afterward, the POS terminal sends the obtain...

Problems solved by technology

[0003] But, above-mentioned way can exist certain problem in practical application: POS terminal needs to carry out information interaction with POS service platform through its own communication module, and described communication module can be modem (Modem) module, Transmission Control Protocol (TCP, Transmission Control). Protocol) communication module, General Packet Radio Service (GPRS, General Packet Radio Service) communication module, Code Division Multiple Access (CDMA, Code Division Multiple Access) communication module, etc., can be built-in or plug-in, because the above-mentioned communication modules are usually very large , so the mobility of the POS terminal is very poor, that is, it can only be fixed in a certain place. In this way, if the communication signal of the place is not good, it may cause the transaction to fail, thereby reducing the user experience
