QR Code Mobile Payment Transfer via Encrypted SMS
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing payment systems require a Point Of Sale (POS) device and credit or debit cards, limiting transactions to parties with access to these, and are inefficient due to server overload and data interception risks.
Innovation Solution
A method using two-dimensional image codes, specifically QR codes, between mobile phones for secure, efficient, and private money transfers between parties without the need for POS devices or credit/debit cards, utilizing a central server for registration, authorization, and payment management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a POS device and credit/debit cards are used for payment, then transactions can be authorized and processed, but the system requires parties to have access to POS devices and cards, limiting transaction flexibility
Solution Approach 1:
The patent extracts the essential payment authorization function from the complex POS device and card system. Instead of requiring physical cards and POS terminals, the invention uses a mobile phone with camera to capture a two-dimensional code that contains all necessary payment information, thereby eliminating the need for traditional payment devices while maintaining transaction authorization capability
Solution Approach 2:
The patent creates a digital copy of payment information in the form of a two-dimensional code that can be captured by a mobile phone camera. This code contains encoded payment data that replaces the need for physical credit/debit cards and POS terminals, allowing transactions to be initiated through simple image capture rather than complex device interaction
2Productivity
If traditional payment systems with servers are used, then payments can be processed, but servers become overloaded during high transaction periods
Solution Approach 1:
The patent segments the payment process into independent stages: the buyer initiates payment by capturing a code, the server only performs lightweight verification of the code format and sends authorization, and the actual money transfer occurs through the mobile phone network. This segmentation reduces server load by eliminating the need for the server to handle complete transaction processing during high-volume periods
3Reliability
If card data is transmitted through POS systems, then payments can be processed, but data interception and cloning risks increase
Solution Approach 1:
The patent uses a two-dimensional code as a secure digital copy that contains encrypted payment information. The code is captured by the buyer's camera and transmitted through the mobile phone network, eliminating the need to transmit sensitive card data through potentially vulnerable POS systems. The code can be verified by the server without exposing underlying card information
Solution Approach 2:
The patent replaces the mechanical card-swiping or magnetic stripe reading process with an optical capture system using the mobile phone camera. This substitution eliminates physical contact between cards and POS terminals, thereby preventing data interception through skimming devices and cloning through magnetic stripe copying

AI summary
The present disclosure concerns methods and systems for transferring a money amount by using a two-dimensional image code (3). The request of the recipient party to the paying party of the money amount occurs by a two dimensional image code (3) generated on the display of a mobile phone of the recipient party; the payment order of the paying party to the managing entity to pay said money amount comprises the capture of the two-dimensional image code (3) from the display of the recipient party and by sending to the managing party of 15 an encrypted SMS message including the data contained in the two-dimensional image code (3), the reception of the encrypted SMS message by a central server (2) of the managing party, which forwards or not the request of authorization of payment of the money amount.
