Problems solved by technology

The method obtains the location information of the credit card machine through the transaction message or the wireless network server, and the transaction message will increase the complexity and processing time of the transaction process, which will inevitably affect the user experience; in addition, it needs to be connected to the wireless network Only after that can it be judged whether it is an off-site transaction, and the positioning accuracy of a single wireless communication network is limited, and it cannot completely prevent the card reader from conducting off-site transactions

Embodiment 1

[0068] Please refer to figure 1 , The first embodiment of the present invention is:

[0069] A method for preventing POS machines from remote transactions, the method is:

[0070] The initial position information of the POS machine is preset and stored; according to the initial position information, the POS machine scans the wireless AP and obtains the initial AP list, and stores the initial AP list;

[0071] The POS machine scans wireless APs and obtains the current AP list, and stores the current AP list;

[0072] The preset AP list similarity threshold is as follows:

[0073] In three days, compare and record the similarity S between the current AP list of each POS machine transaction and the initial AP list in N POS transactions i , I=1,2,...,N, take N S i If the minimum similarity is greater than 0, if it is 5%, transform 5%: 5%*100=5, and use the transformed value 5 as the AP list similarity threshold;

[0074] Compare the similarity between the current AP list and the initial AP l...

Embodiment 2

[0094] Please refer to Figure 4 , The second embodiment of the present invention is:

[0095] A system for preventing POS machines from remote transactions, including:

[0096] The storage module is used to store the initial AP list, current AP list, initial location information, and current location information;

[0097] Scanning module for scanning wireless AP;

[0098] The obtaining module is used to obtain the initial AP list and the current AP list;

[0099] The comparison module is used to compare the similarity between the current AP list and the initial AP list, and to compare the distance between the current location information of the POS machine and the initial location information;

[0100] The acquisition module is used to acquire the current position information of the POS machine.

[0101] The system also includes a POS machine and a POS transaction server. The POS machine also includes a Wi-Fi module and an LBS information module. The scanning module and the acquisition ...

Abstract

The invention provides a method and a system for preventing a POS machine from being transacted in different regions. The method comprises the steps as follows: presetting initial position information of the POS machine and storing; scanning a wireless AP and obtaining an initial AP list with the POS machine according to the initial position information and storing the initial AP list; scanning the wireless AP and obtaining an initial AP list with the POS machine according to the current position information and storing the current AP list; presetting a similarity threshold value of the AP list and comparing the similarity of the current AP list with that of the initial AP list; allowing to perform POS transaction if the similarity is more than or equal to the similarity threshold value of the AP list, otherwise obtaining the current position information of the POS machine and storing; a presetting a displacement distance threshold value, comparing the distance of the current position information and initial position information of the POS machine; allowing to perform the POS transaction if the distance is less than the displacement distance threshold value, otherwise, not allowing to perform POS transaction. The method and the system of the invention simplify the flow of card swiping transaction of the POS machine and improve user experience.

Description

Technical field [0001] The invention relates to a payment management method, in particular to a method and a system for preventing POS machines from remote transactions. Background technique [0002] UnionPay stipulates that POS machines must be used at the business address applied by the merchant. As long as it is not used at the application address, it is regarded as remote use, even if it is used by the neighboring merchants, it is also regarded as remote use. However, in the existing transaction process, there is no reliable technical means to detect whether the POS device is used in a different place. Therefore, many criminals apply for POS machines to conduct virtual transactions in remote places and conduct illegal activities such as illegal cashing out of signal cards for others. [0003] The current methods to prevent POS machines from conducting remote transactions mainly include POS machine location positioning and UnionPay's strengthening of supervision. POS machine ...
