Two-dimensional code generation method, system, implementation method and payment device

Abstract

The invention discloses a two-dimensional code generation method, system, implementation method and payment device. The two-dimensional code generation method includes the following steps: respectively screening the lowest two-dimensional code version that can accommodate the information to be encoded under four error correction levels; According to the screen resolution, calculate the maximum magnification of the two-dimensional code pattern to be enlarged under each of the lowest two-dimensional code versions of the information to be encoded respectively; select the two-dimensional code pattern to be enlarged with the largest maximum magnification and the largest size, And zoom in according to its maximum magnification. The two-dimensional code generation method provided by the present invention enlarges the generated two-dimensional code pattern to maximize its proportion in the display area of ​​the screen. On the one hand, it can improve the scanning speed; , because the proportion of the QR code pattern in the screen display area is maximized after being enlarged, and the code can also be successfully scanned, so you can choose to use a low-resolution screen, and the low-resolution screen has low power consumption, which greatly reduces the cost.

Description

technical field [0001] The invention relates to the field of two-dimensional code payment, in particular to a two-dimensional code generation method, system, implementation method and payment device. Background technique [0002] With the development of mobile payment, two-dimensional code scanning payment has been widely used in the field of daily consumption, and payment can be completed by scanning two-dimensional code, which has become the payment method used by most merchants and consumers. [0003] At present, the code scanning payment devices on the market generally use high-resolution color screens. For a piece of information to be encoded, the size of the generated two-dimensional code is determined by using a certain error correction level and version. For a display with the same display area, the high-resolution LCD (Liquid Crystal Display) is Compared with the high-resolution screen, the magnification factor of the low-resolution screen is limited or even imposs...

Problems solved by technology

[0004] However, the cost of high-resolution LCD is high, and the power consumption is also high. If the same working time is required, a high-capacity battery is required, both of which increase the cost of the two-dimensional code device.

[0005] Moreover, the current payment devices will control the device to enter the low-power sleep mode in order to prolong the working time. Existing products usually adopt the low-power sleep mode of the whole machine, and manual operation is required to wake up the device during use, which also affects the user's work efficiency.
