Referring to Fig. 1, an embodiment of the present invention provides a method for inputting payment amount by scanning a code, which is executed by a mobile terminal. The mobile terminal includes but is not limited to a mobile phone, a tablet, etc. The method includes steps S10 to S60, as follows:

S10, listening to the event that the mobile terminal starts scanning and payment.

In the embodiment of the present invention, the scanning payment event means that the payer, that is, the user, activates the payment function of Alipay, WeChat, online banking, etc. by scanning QR codes or one-dimensional codes, for example, scanning. When the user clicks the scan function, the scan payment event is started.

S20. Obtain the payment merchant of the current code scanning transaction through the two-dimensional code scanned by the camera device of the mobile terminal when the scanning payment event is detected.

In the embodiment of the present invention, when the scanning payment event is started, the mobile terminal will invoke its camera device to scan and obtain the QR code, and obtain the payment merchant information of the current code scanning transaction according to the QR code.

S30. Obtain the current positioning location of the mobile terminal, and use the positioning location as the transaction location of the current scanning code transaction.

Since the same merchant can set up stores in different geographic locations, it is not accurate enough to judge payment habits based on payment merchant information only. Therefore, the GPS function of the mobile terminal can be used to locate the current geographic location of the mobile terminal, and the geographic location The position is the transaction position of the current scan code transaction.

S40, according to the scanning time of the current code scanning transaction, obtain the historical payment information of the historical scanning code transaction that is not on the same day as the scanning code time but within the same time period; wherein, the historical payment information includes the historical scanning code transaction The payment amount, payment merchant and transaction location of code transactions.

Assuming that the scanning time of the current code scanning transaction is 10:30 on Monday, February 5, 2018, the mobile terminal can preset a time threshold, for example, the time period between half an hour before and half an hour after the current scanning time For the same time period, another time threshold can also be preset, which is limited to historical payment information within one month. Taking the above as an example, from January 4, 2018 to February 4, 2018 and located on the same day Historical payment information from 10:00 to 11:00 can be extracted. The above time threshold can be set according to specific situations. But it should not be too long to ensure accuracy.

S50. Calculate the payment amount of the current code scanning transaction according to the payment merchant and transaction location of the current code scanning transaction and the historical payment information.

Since the extracted historical payment information is only screened based on time conditions, it is necessary to further determine the transaction habits closely related to the current code scanning transaction based on the payment industry and transaction location of the current code scanning transaction. Specifically, as shown in FIG. 2, this step S50 can be specifically performed as follows:

S51. Count the number of transactions with the same payment amount according to the extracted historical payment information.

In this embodiment, for example, the payment amount of historical payment information, the following enumeration occurs: 20rmb, 20rmb, 19rmb, 18rmb, 20rmb, 19rmb, 18rmb, 20rmb, 19rmb; then, the number of transactions for the payment amount of 20rmb is 4 times , for the payment amount of 19rmb, the number of transactions is 3 times, and for the payment amount of 18rmb, the number of transactions is 2 times. In this embodiment, an event in which the number of transactions of the same payment amount is greater than the preset number of times threshold is an event; for example, assuming that the number of times the threshold is 3 times, then the event that the number of transactions of the same payment amount is greater than the preset number of times threshold occurs The quantity is 1 time; assuming that the number of times threshold is 2 times, then the number of events where the number of transactions with the same payment amount is greater than the preset number of times threshold is 2 times.

S52. When the number of code-scanning payment events is greater than 1, calculate the payment amount of the current code-scanning transaction according to the payment amount of each code-scanning payment event.

In this embodiment, when the number of scanning payment events is greater than 1, it means that there are multiple transactions with the same payment amount that meet the conditions and are greater than the threshold value. For example, taking the above example as an example, assuming that the threshold value is 2, Then, the number of scanning payment events is 2 times, including: 4 transactions for a payment amount of 20 rmb, and 3 transactions for a payment amount of 19 rmb. Then, the corresponding payment amount is calculated according to the payment amount of the two scanning code payment events. In a concrete example, the process could be as follows: Determine whether the payment amount of any two scan code payment events is greater than the preset threshold; if so, select the scan code payment event with the highest number of transactions, and use the payment amount of the scan code payment event as the current code scan transaction Payment amount; If not, according to the payment amount of all scan code payment events, select the payment amount in the median as the payment amount of the current scan code transaction.

It should be noted that if the difference between the payment amounts of the two scanning code payment events is too large, then the probability of the payment amount of the scanning code payment event with the highest number of transactions will be higher, and the payment amount is used to determine the current The payment amount of the scan code transaction is conducive to the accuracy of the extraction prediction, and when the difference in the payment amount is not large, then in these scan code payment events, the probability of the occurrence of the median payment amount is updated, with the payment amount To determine the payment amount of the current scan code transaction is conducive to the accuracy of the prediction prediction.

S53. When the occurrence number of the code scanning payment event is equal to 1, calculate the payment amount of the current code scanning transaction according to the payment amount of the code scanning payment event. Preferably, since there is only one event where the number of transactions of the same payment amount is greater than the number threshold, the payment amount of this one code scanning payment event can be used as the payment amount of the current code scanning transaction.

S54, when the number of occurrences of the scan code payment event is less than 1, extract again from the extracted historical payment information the scan code payment that is at the same week cycle position as the scan code time of the current scan code payment and is closest to the current time information, and calculate the payment amount of the current scan code transaction based on the payment amount of the scan code payment information extracted again.

It should be noted that, taking the scanning time of the current code scanning payment as an example above, the code scanning payment information extracted again can be from January 4, 2018 to February 4, 2018 and located on the same day The time period from 10:00 to 11:00 and the historical payment information of the Monday closest to the current time. In the process of re-extracting historical payment information, it is possible that no information can be extracted, that is, there is no transaction information that satisfies the extraction conditions. Then in step S54, "according to the payment amount of the re-extracted scan code payment information, calculate the current scan code The payment amount of the transaction" process can be:

Determine whether the code scanning payment information extracted again is empty information; if so, determine that the payment amount of the current code scanning transaction is zero; if not, use the payment amount of the code scanning payment information extracted again as the payment amount of the current code scanning transaction Payment amount.

S60. Generate and display a payment display interface according to the payment merchant and the payment amount of the current code scanning transaction. Since the calculated payment amount may be zero during the execution of step S60, the execution process of this step S60 can be:

Judging whether the payment amount of the current code scanning transaction is zero; if so, when generating the payment display interface, controlling the payment amount input box of the payment display interface to be empty; if not, controlling the payment amount input box when generating the payment display interface The value of the payment amount input box on the payment display interface is the payment amount of the current scan code transaction.

The method for inputting the payment amount by scanning the code provided by the embodiment of the present invention can obtain the transaction location of the current code scanning transaction when scanning the code to the payment merchant of the current code scanning transaction, and obtain the corresponding transaction location according to the scanning time of the current code scanning transaction The historical payment information of the current scan code transaction can be combined with the payment merchant and transaction location with the historical payment information to calculate the payment amount of the current scan code transaction, and finally generate a payment based on the current payment merchant and payment amount submitted by the scan code Display the interface and display it in the interface of the mobile terminal, accurately predict the payment amount of the current scan code transaction according to the payment habit, without the need for the payer to input the payment amount, and reduce the payment queuing time.
