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

Abstract

The invention discloses a two-dimensional code generation method and system, an implementation method and a payment device. The two-dimensional code generation method comprises the following steps of:respectively screening lowest two-dimensional code versions capable of accommodating to-be-coded information under four error correction grades; according to the screen resolution, respectively calculating the maximum magnification times of the to-be-magnified two-dimensional code pattern of the to-be-coded information under each lowest two-dimensional code version; and selecting a to-be-amplified two-dimensional code pattern with the maximum magnification factor and the maximum size, and amplifying the to-be-amplified two-dimensional code pattern according to the maximum magnification factor. The invention provides a two-dimensional code generation method. The generated two-dimensional code pattern is amplified; compared with the prior art, the method has the advantages that the proportion of the two-dimensional code pattern in the screen display area is maximized, on one hand, the code scanning speed can be increased, on the other hand, the proportion of the two-dimensional code pattern in the screen display area is maximized after the two-dimensional code pattern is amplified, code scanning can also be successful, the low-resolution screen can be selected and used, power consumption of the low-resolution screen is low, and cost is greatly reduced.

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.
