detailed description

The following are some of the various embodiments of the invention, which are intended to provide a basic understanding of the invention. It is not intended to identify key or critical elements of the invention or the scope of the invention.

As shown in FIG. 1, the mobile station monitoring method of the POS terminal of the present invention includes the following steps:

The check-in information generating step S100: the POS terminal generates the sign-in information, and sends the generated check-in information to the transaction server;

Mobile phone sign-in step S200: obtaining the check-in information from the mobile POS by using a mobile phone in a prescribed communication manner, Locating the location of the mobile phone according to the specified positioning manner and using the mobile phone location information as the check-in location information, and sending the check-in information obtained by the mobile phone and the check-in location information to the transaction server;

The check-in processing step S300: the transaction server determines whether the check-in information sent from the POS terminal is consistent with the check-in information sent from the mobile phone, and if yes, continues the following transfer risk determination step, otherwise the check-in fails;

The transfer risk determination step S400: comparing the check-in location information with the merchant location information stored in the merchant database, and if the deviation between the two is within the specified range, it is determined that there is no transfer risk, otherwise it is determined that there is a transfer risk.

Next, the check-in information generating step S100, the mobile phone sign-in step S200, the check-in processing step S300, and the transfer risk determination step S400 will be specifically described.

Specifically, in the check-in information generating step S100, the POS terminal generates the check-in information including the merchant number, the terminal number, the check-in time and the like, and sends the check-in information to the transaction server, and on the other hand, the check-in information generated by the POS terminal is provided in a manner that the mobile phone can acquire. Give the phone.

For example, the POS terminal may generate a two-dimensional code or barcode containing the above-mentioned check-in information and display it on the screen of the POS terminal to provide the mobile phone for scanning acquisition, or the POS terminal may generate a sound wave including the above-mentioned sign-in information to emit sound waves when the mobile phone approaches the mobile phone. Acquiring, or the POS terminal can also generate a Bluetooth signal containing the above-mentioned check-in information for the mobile phone to obtain when the mobile phone is approaching.

Moreover, the POS terminal dynamically generates the sign-in information, for example, the sign-in information generated by the POS terminal setting is valid (for example, 10 seconds), and the sign-in information generated after the predetermined time is exceeded (for example, a two-dimensional code, a barcode, a sound wave, or Bluetooth signals, etc.) will be invalid.

In the mobile phone sign-in step S200, the mobile phone obtains the merchant number, the terminal number, the check-in time, and the check-in time from the POS terminal by using a predetermined communication method, such as a short-range wireless transmission method, a barcode recognition method, a sound wave recognition method, or the like. The check-in information of the information determines the current mobile phone location according to various positioning methods, for example, according to GPS positioning, or determining the location of the base station where the current mobile phone is located according to the mobile base station signal, or determining the current mobile phone location according to the mobile base station signal.

Specifically, the first positioning method (GPS positioning mobile phone position): if there is a GPS signal, the mobile phone can directly obtain the latitude and longitude information of the current mobile phone location; the second positioning mode (positioning the base station location): if the GPS signal is not located If there is no GPS signal, the current mobile phone sends the request information to the surrounding base station to obtain the current base station information, including the country code (MCC, Mobile Country). Code), network code (MNC, Mobile Network Code), location area code (LAC), current base station number information (CID, Cell ID), the latitude and longitude of the base station as the check-in location information; the third positioning method ( Positioning the mobile phone based on the mobile base station signal): If the GPS positioning is unsuccessful or there is no GPS signal, COO (Cell of Origin) positioning, TOA (Time of Arrival) positioning, TDOA (based on mobile base station signal) Time Difference of Arrival, location method, etc., to obtain the latitude and longitude information of the current mobile phone, and use the latitude and longitude information as the check-in location information.

Among them, COO positioning is the main positioning technology for GSM network to obtain location information to implement location service. It is a Cell-ID based positioning technology, and the location of the user is determined by collecting the cell identification number (Cell-ID number) where the mobile station is located. As long as the system can collect the geographical location of the cell site where the mobile station is located on the map and the coverage radius of the cell, when the mobile station registers with the cell, the system knows which cell the mobile station is in. The positioning accuracy of this technology depends on the radius of the cell. For example, in urban areas, the base station density is high, and the COO positioning accuracy can reach 200 meters. In the suburbs, the base station density is low, and the COO positioning accuracy can only reach one or two kilometers. . The basic principle of the TOA positioning technology is to determine the location of the mobile terminal by measuring the time when the radio wave propagates from the mobile terminal to the plurality of base stations. The TDOA positioning determines the location of the mobile terminal by detecting the time difference between the signals arriving at the two base stations. Two TDOAs can be detected by three different base stations, and the mobile station is located at the intersection of two hyperbolic curves determined by TDOA.

Next, in the check-in processing step S300, the transaction server determines whether the check-in information transmitted from the POS terminal matches the check-in information transmitted from the mobile phone. If they match, the following transfer risk determination step is continued, otherwise the check-in failure is returned. Specifically, it is determined whether, for example, the merchant number, the terminal number, the check-in time, and the like included in the check-in information sent from the POS terminal, such as the merchant number, the terminal number, the check-in time, etc., included in the check-in information sent from the mobile phone. Consistent, returning to check-in fails in case of inconsistency.

In the transfer risk determination step S400, the check-in location information uploaded from the transaction server and the merchant location information stored in the merchant database are compared, and if the deviation between the two is within the specified range, it is determined that there is no transfer risk, otherwise it is determined that there is a shift. Machine risk.

If in the case of the first positioning method, the latitude and longitude information of the mobile phone obtained by the GPS positioning of the mobile phone and the latitude and longitude information of the merchant stored in the merchant database are compared; if the second positioning mode is used, the mobile phone is compared. Longitude and latitude information of the base station and merchant latitude and longitude information stored in the merchant database; if in the case of the third positioning method described above, the signal positioning by the mobile base station is compared The latitude and longitude information of the mobile phone and the latitude and longitude information of the merchant stored in the merchant database.

The specific implementation of the POS terminal transfer monitoring system of the present invention will be described below.

As shown in FIG. 2, the mobile station monitoring system of the POS terminal according to an embodiment of the present invention includes: a POS terminal 100, a mobile phone 200, a transaction server 400, a transfer risk determination system 500 location server 600, and a merchant for storing merchant profile data. The archive database 700 is a base station location database 800 for storing base station location information.

In the present embodiment, a transfer monitoring system in which a POS terminal 100 and a mobile phone 200 communicate by scanning a two-dimensional code will be exemplified.

In the embodiment, the software modification on the ordinary POS terminal is performed, so that the generation of the sign-on two-dimensional code generation function is increased, and such transformation is only a software modification, and the hardware is not required to be modified, which is beneficial to cost saving and more Conducive to promotion and use.

In this way, the POS terminal 100 dynamically generates the check-in information including the merchant number, the terminal number, the check-in time, and the check information, and the check-in information is displayed on the screen of the POS terminal 100 in the form of a two-dimensional code for the mobile phone 200 to scan later. Here, an effective period (for example, 10 seconds, 20 seconds, etc.) may be set for the generated two-dimensional code, and the two-dimensional code is invalid after expiration. This will further ensure real-time and security.

On the other hand, the POS terminal 100 also transmits the generated check-in information to the transaction server 400.

The cashier opens the camera of the handset 200 and scans and identifies the two-dimensional code displayed on the screen of the POS terminal 100. The mobile phone 200 can obtain the check-in information including the merchant number, the terminal number, the check-in time, and the check information by recognizing the two-dimensional code.

On the other hand, the mobile phone 200 uses the above three positioning methods, that is, GPS locates the mobile phone location, locates the base station location, locates the mobile phone location based on the mobile base station signal, and obtains the current location of the mobile phone or the location of the base station where the mobile phone is located as the check-in location information, and the mobile phone 200 The check-in identification acquired sign-in information and the location-acquired check-in location information are forwarded to the transaction server 400.

Specifically, in the case of the first positioning mode, if there is a GPS signal, the mobile phone 200 can directly acquire the latitude and longitude information of the current location of the mobile phone through the GPS signal. In this case, the location server 600 and the base station location in FIG. Database 800 can be omitted as needed. That is to say, in this case, the mobile phone 200 uses the latitude and longitude information of the current location of the mobile phone obtained by the GPS signal as the check-in location letter. interest.

In the case of the second positioning mode, if the GPS signal is not successfully located or has no GPS signal, the current mobile phone 200 transmits the request information to the surrounding base station 300 to acquire the current base station information, and obtains the base station location database 800 from the base station location database 800 by using the location server 600. Base station information including country code (MCC, Mobile Country Code), network code (MNC, Mobile Network Code), location area code (LAC, Location Area Code), current base station number information (CID, Cell ID), and Location information (e.g., base station latitude and longitude) is used as the check-in location information.

In the case of the third positioning mode, if the GPS positioning is unsuccessful or there is no GPS signal, the positioning may be performed based on the mobile base station signal. Specifically, for example, the mobile phone 200 and the location server 600 adopt COO positioning, TDOA positioning, TOA positioning, and the like. The positioning method acquires the latitude and longitude information of the current mobile phone 200, and uses the latitude and longitude information as the check-in location information.

In the case of the second and third positioning modes, the check-in location information may be sent back to the mobile phone 200 and then sent by the mobile phone 200 to the transaction server 400 and then forwarded to the transfer risk determination system 500, or may be directly sent by the location server 600. It is sent to the transfer risk assessment system 500.

The transaction server 400 receives the check-in information from the POS terminal 100, and also receives the check-in information (and the check-in location information uploaded from the mobile phone 200) recognized by the mobile phone 200 from the mobile phone 200. The transaction server 400 first compares whether the sign-in information uploaded from the POS terminal 100 is consistent with the sign-in information uploaded from the mobile phone 200, and if so, continues the subsequent steps, for example, transmitting the sign-in information together with the sign-in location information to the transfer risk determination system 500. If the two check-in messages are inconsistent, the check-in fails.

The transfer risk determination system 500 compares the check-in location information sent from the transaction server 400 (or may also be from the location server 600) with the merchant location information read from the merchant database 700 based on the check-in information, if the deviation between the two is specified Within the scope, it is judged that there is no risk of transfer, otherwise it is judged that there is a risk of transfer. For example, in the case of the first type of positioning, the mobile risk determination system 500 determines whether the latitude and longitude of the mobile phone and the merchant's latitude and longitude registered by the merchant in the merchant database 700 are consistent; in the case of the second positioning mode, the transfer is performed. The risk judgment system 500 determines whether the latitude and longitude information of the base station where the mobile phone is located and whether the latitude and longitude of the merchant registered in the merchant database 700 are consistent; in the case of the third positioning method, the mobile risk determination system 500 determines the latitude and longitude of the mobile phone and Whether the merchant's latitude and longitude of the merchant registered in the merchant database 700 is consistent.

The transfer monitoring system of the POS terminal of the present invention and the transfer monitoring method of the POS terminal are adopted in The POS terminal sign-in link increases the sign-in of the mobile terminal, and determines the location of the POS machine by using the GPS positioning of the mobile phone or the positioning of the mobile base station, thereby effectively identifying whether there is a risk of the transfer. The transfer monitoring system of the POS terminal of the present invention and the transfer monitoring method of the POS terminal do not need to perform a large number of hardware transformations, and only need to perform necessary program update on the POS terminal, fully utilize the functions already possessed by the smart phone, and can save the transformation cost, Easy to popularize.

The above examples mainly illustrate the transfer monitoring system of the POS terminal of the present invention and the transfer monitoring method of the POS terminal. Although only a few of the specific embodiments of the present invention have been described, it is understood that the invention may be embodied in many other forms without departing from the spirit and scope of the invention.
