Problems solved by technology

With the development of science and technology, various new payment methods are constantly emerging. For example, payment methods that use mobile devices (mobile phones) as payment media cannot be completed through traditional POS systems.
[0006] The existing two-dimensional code image reading only considers grayscale binarization and then rotates to separate the binary code stream. However, in actual situations, especially when t...

Embodiment 1

[0148] S101, the QR code image collected by the camera of the cash register, such as Figure 7 ;

[0149] S102, will Figure 7 A grayscale image is obtained after grayscale, such as Figure 8 ;

[0150] S103, judging Figure 8 If the unsharpness does not exceed the threshold, go to S105;

[0151] S105, will Figure 8 Binarization processing, this example uses the otsu algorithm, such as Figure 9 ;

[0152] S106, judging Figure 9 If the unsharpness does not exceed the threshold, go to S108;

[0153] S108, using the position detection graphic method to calculate the rotation angle;

[0154] S109, use the bilinear interpolation method to rotate the image to a horizontal position, such as Figure 10 ;

[0155] S110, judging whether the decoding is successful, this example is successful, output information:

[0156] "Mobile phone number: 13023956999

[0157] Bank: Bank of China

Embodiment 2

[0162] S101, the QR code image collected by the camera of the cash register, such as Figure 11 ;

[0163] S102, will Figure 11 A grayscale image is obtained after grayscale, such as Figure 12 ;

[0164] S103, judging Figure 12 If the unsharpness does not exceed the threshold, go to S105;

[0165] S105, will Figure 12 Binarization processing, this example uses the otsu algorithm, such as Figure 13 ;

[0166] S106, judging Figure 13 If the unsharpness has exceeded the threshold, go to S112;

[0167] S112, re-binarize the grayscaled image, this figure uses the niblack algorithm, such as Figure 14 ;

[0168] S113, judging Figure 14 If the unsharpness does not exceed the threshold, go to S108;

[0169] All the other are with embodiment 1.

Embodiment 3

[0171] S101--S109 steps are the same as embodiment 1, after obtaining the image after rotation, as Figure 15 , in step S110, if the decoding is unsuccessful, go to S111;

[0172] S111, judging that the filter has not been passed, and turning to S107;

[0173] S107, perform median filtering on the binarized image, and the filter window coefficient used for filtering in this embodiment is

Abstract

The invention discloses a payment method capable of consumption payment by a mobile phone on the basis of two-dimensional code and a payment system thereof. The payment system is composed of a two-dimensional code image (1) and a mobile phone payment part (2), wherein the two-dimensional code image obtains a corresponding bank credit card from the mobile phone, and the mobile phone payment part adopts the mobile phone for consumption payment after customers consume. A camera on a cash register is used to read a two-dimensional code stored on a mobile phone to extract information from a client bank credit card and connect to a bank system for consumption payment for the client. The invention adds a new consumption payment mode on the basis of the original card swiping consumption, i.e. the mobile phone is used for payment, thus solving the problems of various bank cards, difficult carrying and the like in the prior art. The invention can adopt mobile phones for consumption payment without swiping cards, safely and conveniently realizes relative payment from mobile phones to bank system modes, reduces troubles for clients to carry various bank credit cards, improves reading speed and efficiency, and has the advantage of favourable instantaneity, and is simple and practical.

Description

technical field [0001] The invention relates to a payment method for consumption settlement and a payment system thereof, in particular to a payment method and a payment system for consumption settlement using a mobile phone based on a two-dimensional code. Background technique [0002] In today's information age, mobile phones have spread in every corner of people's lives. With the convenience of carrying them anytime, anywhere, they will become an important application tool for people's business and life in the future, and they are indispensable for people now. According to statistics, by the end of 2008, my country's mobile phone customer population had reached 420 million, and it has already become the world's largest mobile phone owner. [0003] A two-dimensional barcode is a barcode that stores information in a two-dimensional space in the horizontal and vertical directions, that is, a two-dimensional barcode is a black and white graphic recording data symbol that is d...
