Embodiment 1

[0032] There may be some unsafe problems based on the static two-dimensional code, the embodiment of the present invention provides a method for generating a dynamic two-dimensional code,

[0033] Such as figure 1 As shown, the method specifically includes:

[0034] Step 101, start the device, and perform system initialization;

[0035] In this embodiment, starting the device includes: the device detects whether there is a USB plugged in, if so, the device starts up, if otherwise, the device starts up after the power button is triggered;

[0036] In this embodiment, the system initialization of the device specifically includes: the device judges whether to calibrate or set the time, if not, displays "Please calibrate or set the time" on the display screen; if so, checks whether the device is demolished;

[0037] The device detects whether it has been demolished, and if so, erases the sensitive data in the device chip and displays "device has been demolished" on the display s...

Embodiment 2

[0066] An embodiment of the present invention provides a device for generating a dynamic two-dimensional code,

[0067] Such as figure 2 As shown, the device 10 specifically includes:

[0068] Acquisition module 11, calculation module 12, signature module 13, combination module 14, generation module 15, display module 16, judgment module 17;

[0069] An acquisition module 11, configured to acquire first transaction data;

[0070] The first transaction data acquired by the acquisition module 11 includes transaction data elements; the transaction data elements can be imported by the generation tool, or can be input by the input module;

[0071] Specifically, in this embodiment, the transaction data element in the first transaction data includes at least one of the following: acquirer code, equipment certificate serial number, transaction type, transaction subcategory, product type, merchant number, equipment serial number, Order number, order time, transaction amount.

Abstract

The invention discloses a dynamic two-dimensional code generation method and device. Acquired data elements such as current time are added into transaction data for generating a two-dimensional code,therefore, the two-dimensional code generated each time is ensured to be unique; the two-dimensional code refreshing time is set, whether the obtained current time meets the two-dimensional code refreshing time or not is judged, if yes, the two-dimensional code is refreshed, a new two-dimensional code is generated and displayed on the device, the dynamic two-dimensional code can be achieved on thedevice through the method, and therefore the problems of quota limitation, replacement and the like of merchants are solved.

Description

technical field [0001] The invention relates to the field of computer application technology, in particular to a method and device for generating a dynamic two-dimensional code. Background technique [0002] QR code payment is a new generation of wireless payment solution based on the account system. It has become the main force of mobile payment and has been widely promoted in the payment field with its fashionable and convenient customer experience. Usually, merchants compile transaction information such as account numbers and product prices into a two-dimensional code, and users can scan the two-dimensional code through the mobile client to realize payment and settlement with the merchant's account. However, because many QR codes are static, some unscrupulous people take advantage of people's habit of relying on smart consumption to break the law and commit crimes. Recently, I have seen many news reports that someone replaced the QR code on the shared bicycle and remitte...
