Jector, a stablecoin payment infrastructure company, has completed registration of a patent covering technology designed to connect visual payment codes with external blockchain wallets, according to a company announcement.
The patent addresses a key requirement for bringing digital assets into everyday commerce by allowing blockchain-based payments to be initiated through familiar visual codes. The system is designed to turn digital asset transfers into a payment process that can be used across physical and online merchant environments.
Patent Targets Real-World Digital Asset Payments
The newly registered intellectual property covers a wallet-based on-chain payment method and system using visual codes. While QR codes are a central application, the technology also supports other camera-readable formats, including barcodes and Data Matrix codes.
Under the system, a merchant can display a visual code containing information such as the recipient wallet, payment amount, and order details. The code may appear on a point-of-sale terminal, kiosk, or online payment screen. A customer can then scan the code using an external blockchain wallet and initiate an on-chain transaction.
The system is designed to verify that the payment request and the resulting blockchain transaction are consistent before allowing the asset transfer to proceed, adding safeguards against forged or manipulated payment information.
The technology uses smart contracts to check transaction details against the original payment request. The system also incorporates electronic signatures intended to detect forgery or tampering. Additional mechanisms, including random values and validity periods, are designed to prevent an expired payment request from being reused.
The approach could allow merchants to accept blockchain-based payments without requiring customers to navigate a separate process specifically designed around blockchain technology. By presenting the payment through established visual-code interfaces, the technology seeks to make digital asset transactions more compatible with existing commerce infrastructure.
Stablecoin Infrastructure Expands
The patent builds on Jector’s earlier intellectual property covering technology for automating collateral-backed stablecoin issuance, collateral management and liquidity adjustments.
The company has been developing infrastructure aimed at connecting stablecoins with practical payment applications. Its latest patent extends that work from stablecoin operations toward the transaction interface used by merchants and consumers.
Jector said the technology could enable digital assets to be used in real-world payments through existing merchant environments, potentially reducing the need for businesses to replace established payment interfaces.
The system’s reliance on external wallets is also significant because customers can use wallets they already control rather than being required to adopt a proprietary wallet designed specifically for the payment platform. The transaction remains on-chain while the payment request is presented through a conventional visual interface.
Pilot Planned With B-DAX and Insaengnecut
Jector has also entered a business partnership with B-DAX and LK Ventures, the operator of the self-photo booth brand Insaengnecut, to pilot the payment system.
The pilot is scheduled to take place at the Korea Blockchain Week venue on Oct. 1. It will connect B-DAX’s won-denominated stablecoin KRW1 with the Insaengnecut payment environment.
The planned demonstration will test the payment process across multiple stages rather than focusing only on the initial transaction. Jector said the verification will cover payment requests, approvals, cancellations, refunds, and merchant settlement, with SSDA also involved in the process.
The pilot is intended to provide a practical test of how stablecoin payments can operate within a merchant environment while maintaining transaction verification and settlement procedures.
Jector Chief Executive Yu-jin Lee said the patent could allow consumers to use digital assets through payment experiences similar to QR-based payments without needing to distinguish between blockchain-based and conventional payment processes. She also said merchants could manage the transactions within their existing payment environments.
The company said it expects further cooperation with industry partners and merchants to support proof projects aimed at testing stablecoin and digital asset payments in real commercial settings.
