CBDC Wallet Funding via Fiat Serial Number Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need to convert fiat money into central bank digital currency (CBDC) efficiently, especially when fiat money holders lack access to traditional banking services and need to verify the legitimacy and authenticity of the fiat money before conversion.
Innovation Solution
The proposed solution involves scanning the fiat money to obtain an image, verifying its authenticity by matching the serial number with a central bank's currency registry, and then converting it into CBDC, with safeguards to ensure the fiat money is no longer usable once converted.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If fiat money is converted to CBDC without verification, then conversion speed is improved, but security and authenticity verification deteriorate
Solution Approach 1:
The system performs preliminary verification of fiat money authenticity by scanning and validating serial numbers against the central bank's currency registry before conversion. This preliminary action ensures that only genuine currency is converted, preventing counterfeit money from entering the CBDC system while maintaining efficient processing speeds.
2Reliability
If traditional banking channels are used for conversion, then security is improved, but accessibility for unbanked individuals deteriorates
Solution Approach 1:
The patent introduces a portable scanning device as an intermediary that bridges the gap between physical fiat money and the CBDC system. This intermediary device performs verification and conversion functions previously available only through traditional banks, enabling unbanked individuals to access CBDC securely through a simplified interface that requires no banking infrastructure.
Solution Approach 2:
The system enables self-service conversion by allowing individuals to directly scan and convert their own fiat money using portable devices. The automated verification process against the central bank's registry and the self-executing conversion eliminate the need for bank staff intervention, making the service accessible to anyone with the scanning device while maintaining security through automated validation.
3Measurement precision
If manual verification processes are used, then authenticity checking is improved, but processing time increases
Solution Approach 1:
The patent replaces manual verification processes with automated optical scanning and digital validation systems. The portable scanning device captures images of fiat money and automatically extracts serial numbers, which are then validated against the central bank's currency registry through automated digital communication. This substitution of mechanical manual processes with automated systems maintains high accuracy in authenticity checking while dramatically reducing processing time.

AI summary
Disclosed are various embodiments for funding central bank digital currency (CBDC) accounts by converting funds (e.g., fiat money, representative money, account currency, etc.) into CBDC. A request to fund a central bank digital currency (CBDC) wallet associated with a CBDC wallet address is received. The associated funds can be verified and, in the case of fiat money, confirmed destroyed. A transaction can be generated indicating an addition of CBDC having a CBDC value corresponding to the value of the funds. The transaction can be recorded in a CBDC ledger in association with the CBDC wallet address.
