Optical Scanning Mobile Payment Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for mobile telephone-based authorization and payment processes are time-consuming due to infra-red transmission delays and compatibility issues, particularly in applications like supermarket checkouts.
Innovation Solution
Optical scanning of user identifiers and direct transmission of confirmation messages from mobile telephone terminals to interrogation stations, eliminating the need for intermediate matching devices and reducing delays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If infra-red transmission is used to transmit SIM-card identification, then the mobile telephone can communicate with the vendor terminal, but the transmission time increases and compatibility problems arise
Solution Approach 1:
The patent replaces the infra-red transmission mechanism with optical scanning technology. Instead of using infra-red interfaces that require specific hardware compatibility and protocol agreements, the system uses optical scanners to read identifiers (such as barcodes or QR codes) displayed on the mobile telephone terminal. This substitution eliminates the mechanical/technical compatibility issues of infra-red transmission while maintaining communication capability, thereby resolving the contradiction between reliability and time loss.
2Reliability
If confirmation messages are transmitted through a matching device, then the verification process can be completed, but additional delays are introduced
Solution Approach 1:
The patent extracts and eliminates the matching device from the verification process. Instead of transmitting confirmation messages through a matching device that causes additional delays, the system directly transmits confirmation messages from the mobile telephone terminal to the interrogation station. This extraction of the intermediate component (matching device) maintains verification completeness while significantly reducing the time required for the verification process.
3Reliability
If multiple transmission steps are used for payment confirmation, then the verification process can be thorough, but the overall process becomes time-consuming
Solution Approach 1:
The patent implements preliminary action by having the mobile telephone terminal display the identifier (such as a barcode or QR code) that contains the confirmation information before the actual verification is needed. The optical scanner at the interrogation station can then directly read this pre-prepared identifier, eliminating the need for multiple sequential transmission steps. This preliminary preparation of the identifier maintains verification thoroughness while dramatically improving transaction processing speed.

Function Achieved in This Case
Significantly reduces the time required for authorization and payment transactions by avoiding infra-red transmission delays and compatibility issues, enabling faster verification and payment processing across various application environments.
Implementation Method 1
optically scanning an identifier associated with an authorized user and/or payer, at an interrogation station
Data Source
AI summary
The invention relates to the carrying out of verification processes with regard to authorization of user and/or payment processes by means of a mobile telephone terminal, whereby an identifier associated with an authorized user and/or payer is provided in such a way that it can be called up and represented on a display device of a mobile telephone terminal associated with the authorized user and/or payer. On the instructions of the authorized user and/or payer, the identifier is represented on the display device and optically scanned in an interrogation station. A control message with a request for confirmation of a process verifying the authorization of use and/or payment process is transmitted to the mobile telephone terminal. In order to grant use and/or carry out payment, the control message receives a reply by transmitting a confirmation message from the mobile telephone terminal to the interrogation station.
