Proximity relation detection-based two-dimensional code payment system and method

Abstract

The invention provides a proximity relation detection-based two-dimensional code payment system and method. A collection verification service platform is connected with a two-dimensional code collection module and sends a dynamic identifier code or a dynamic transaction code to the two-dimensional code collection module; the two-dimensional code collection module broadcasts the dynamic identifier code or the dynamic transaction code through WiFi or a BLE link; an intelligent mobile phone obtains the dynamic identifier code or the dynamic transaction code, automatically calls a two-dimensional code reading tool to scan a static two-dimensional code when being judged to be close to the two-dimensional code collection module, packages the static two-dimensional code into a verification request message and sends the verification request message to the collection verification service platform for performing security verification; and the collection verification service platform verifies the uploaded verification message and finishes a payment transaction through a payment interface provided by a payment platform after the verification is passed. According to the system, the dynamic code is introduced based on the static two-dimensional code to perform the security verification, so that the payment security is ensured; and the two-dimensional code reading tool can be automatically called to perform code scanning, so that a payment action is reduced and the payment experience of a user is improved.

Description

technical field [0001] The invention relates to a payment system and method, in particular to a two-dimensional code payment method and system based on proximity relationship detection, which is mainly used in offline mobile payment of smart phones and belongs to the field of mobile payment. Background technique [0002] With the rapid development of the mobile Internet, mobile payment has rapidly penetrated into people's daily life in recent years. Payment methods such as QR codes, NFC (Near Field Communication), and Bluetooth have emerged and been applied one after another. Bluetooth payment belongs to a method of near-field payment. Compared with NFC, its working distance extends from 10cm to tens of meters. Reduced security, large differences in Bluetooth pairing and connection time for different models of smartphones have brought about inconsistent user experience, and most Android smartphone users turn off Bluetooth to save power. These factors have led to Bluetooth pa...

Problems solved by technology

[0006] The purpose of the present invention is to introduce low-cost WiFi on the basis of the static two-dimensional code compatible with merchant standard payment methods to solve the problems of low security existing in the existing two-dimensional code payment method, the need for the user to perform multiple actions during payment, and the complicated process. With Bluetooth Low Energy (Bluetooth Low Energy), by establishing a secure connection with the collection verification service platform, obtain the dynamic identification code of the QR code collection module or the dynamic transaction code generated after the transaction is initiated, and pass the WiFi / BLE unit Broadcast to smartphones, which improves the security of payment and eliminates the potential safety hazard that the static QR code of the payment QR code is easily replaced; at the same time, the smartphone is in the unlocked state and runs a low-power WiFi / BLE interception watch library, based on WiFi / BLE received signal strength RSS realizes the proximity relationship detection between the smartphone and the two-dimensional code payment module, and automatically calls the two-dimensional code reading tool without the need for the user to perform multiple actions. The operation is simple and the user experience is improved
