HTTP-Controlled Scanner for Paper Transaction Data Exchange
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices struggle to facilitate commercial transactions using paper documents on user-owned devices like smartphones and tablets, as they cannot easily capture and decode MICR codes, and require specific software applications and hardware configurations, limiting their use in real-time, mobile, and universal scenarios.
Innovation Solution
A device and method that uses the HTTP protocol to control a reading and scanning device for paper documents, allowing user devices (such as POS terminals, smartphones, and computers) to control data exchange without needing special software or hardware modifications, enabling scanning, reading, and printing through a web browser interface, supporting wired and wireless connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional reading and scanning devices are used for paper documents, then document processing capability is achieved, but device complexity and requirement for specific software configuration increase
Solution Approach 1:
The patent introduces a server as an intermediary between the user device and the reading/scanning device. The server handles all complex software configurations, protocol translations, and data processing operations. The user device only needs to communicate with the server through standard web protocols, eliminating the need for specialized software installations or complex configurations on the user device side.
Solution Approach 2:
The patent replaces the traditional mechanical/software-based control system with a web-based protocol system. Instead of requiring proprietary software applications and device-specific drivers, the system uses standard HTTP/HTTPS web protocols that can be accessed through any modern web browser, thereby substituting complex mechanical/software interfaces with a universal web interface.
2Adaptability or versatility
If proprietary software applications are installed on user devices, then document processing functionality is enabled, but adaptability across different operating systems and hardware configurations decreases
Solution Approach 1:
The patent creates a universal system where a single server implementation can serve multiple types of user devices (smartphones, tablets, computers, POS terminals) running different operating systems (iOS, Android, Windows, macOS, Linux). The server provides a standardized web interface that works across all platforms without requiring platform-specific software versions or installations, thereby achieving multi-functionality and broad adaptability.
3Measurement precision
If specialized hardware configurations are required, then reading and scanning accuracy is improved, but ease of deployment and mobility decreases
Solution Approach 1:
The patent extracts the complex hardware configuration requirements and specialized processing logic from the user device and relocates them to the server environment. The reading and scanning operations can be performed by various devices (mobile phones with cameras, dedicated scanners, POS terminals), and the server handles the sophisticated image processing, MICR code recognition, and data validation, thereby separating measurement functions from processing functions.
4Productivity
If real-time processing is implemented, then transaction speed is improved, but device complexity and processing requirements increase
Solution Approach 1:
The server performs preliminary actions by pre-configuring processing pipelines, pre-loading necessary software components and libraries, and establishing ready-to-use processing templates for different document types. When a document is submitted for processing, the server can immediately apply pre-configured recognition algorithms and validation rules, enabling real-time processing without requiring the user device to have complex processing capabilities.
