Integrated POS Register for Offline Cryptocurrency Payments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems require two terminals, a cryptocurrency payment support terminal and a POS system register, complicating cryptocurrency payments at retail shops and compromising security, as they need to be connected to the Internet for functionality, and often involve third-party financial institutions.
Innovation Solution
An information management system that includes a payment information confirmation device connected to a cryptocurrency system management terminal to extract and generate transaction information, and a register device that converts currency to cryptocurrency units, generates a two-dimensional code, and displays it for user terminals to read, allowing secure cryptocurrency payments without direct Internet connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a cryptocurrency payment support terminal is used to convert payment amount into cryptocurrency and generate transaction information, then cryptocurrency payment functionality is achieved, but the system requires connection to the Internet and involves third-party nodes, compromising security and increasing device complexity
Solution Approach 1:
The patent combines the cryptocurrency payment support terminal functions with the existing POS register into a single integrated system. The register device performs both traditional POS functions and cryptocurrency payment functions by incorporating the conversion and transaction generation capabilities directly within the register, eliminating the need for separate terminals and reducing system complexity
Solution Approach 2:
The register device is designed to perform multiple functions: traditional POS processing and cryptocurrency payment processing. By making the register multi-functional, the system eliminates the need for separate cryptocurrency payment terminals, thereby reducing device complexity while maintaining full cryptocurrency payment capability
2Ease of operation
If cryptocurrency payment support terminal is used, then payment conversion and confirmation are achieved, but the terminal must access Internet nodes, increasing security risks
Solution Approach 1:
The patent introduces an offline transaction information generation mechanism where the register device can generate transaction information locally without direct Internet connection. The system uses pre-stored cryptocurrency address information and conversion rates, allowing the register to function as an intermediary that processes payments offline while maintaining security
Solution Approach 2:
The patent divides the payment processing into separate functional modules: transaction information generation, payment confirmation, and settlement. The register device handles transaction information generation offline, while payment confirmation can be performed later when connected, separating the security-sensitive operations from Internet access requirements
3Adaptability or versatility
If two separate terminals are used for cryptocurrency payment and POS processing, then both functions are achieved, but the payment procedure becomes complicated and efficiency decreases
Solution Approach 1:
The patent merges the cryptocurrency payment support terminal and POS register into a single integrated register device. This consolidation allows both traditional POS processing and cryptocurrency payment processing to occur through one interface, simplifying the payment procedure and improving processing efficiency by eliminating the need to switch between terminals
4Measurement precision
If cryptocurrency address information is displayed as long character strings, then accurate remittance information is provided, but user confirmation becomes difficult and operation complexity increases
Solution Approach 1:
The patent uses visual representations (such as QR codes or graphical displays) to represent cryptocurrency address information instead of displaying long character strings. This allows users to easily verify address information through visual patterns while maintaining the accuracy of the underlying data, significantly improving ease of operation

AI summary
Provided is an information management system that comprises: a payment information confirmation device which is connected over a network to a cryptocurrency system management terminal that manages a cryptocurrency system, which extracts transaction information including address information for a seller account in a cryptocurrency system, and which generates and transmits payment confirmation information including at least a transfer amount from the extracted transaction information; and a register device which is connected to the payment information confirmation device, receives the payment confirmation information from the payment information confirmation device, displays the received payment confirmation information, converts the currency units of an entered transaction amount into a cryptocurrency units payment amount in the currency units of the cryptocurrency system, generates a two-dimensional code in which are recorded the cryptocurrency units payment amount and the address information, and displays the generated two-dimensional code.
