Jector, a stablecoin payment infrastructure company, has completed the registration of a patent covering technology that connects visual payment codes with external blockchain wallets, according to a company announcement.

The patent addresses one of the core requirements for bringing digital assets into everyday commerce: allowing blockchain-based payments to be initiated through familiar visual codes. According to the company, the system is designed to turn digital asset transfers into a payment process that works across both physical and online merchant environments. QR-style codes are a familiar checkout interface in many markets, and bridging that established consumer interaction with on-chain settlement is the gap the registration is intended to close.

Patent Focuses on Real-World Digital Asset Payments

The newly registered intellectual property covers a wallet-based on-chain payment method and system built around visual codes. While QR codes are the central application, the technology also supports other camera-readable formats, including barcodes and Data Matrix codes.

Under the system, a merchant displays a visual code containing information such as the recipient wallet, payment amount, and order details. The code can appear on a point-of-sale terminal, a kiosk, or an online payment screen. A customer then scans the code using an external blockchain wallet to initiate an on-chain transaction.

Before an asset transfer proceeds, the system verifies that the payment request and the resulting blockchain transaction are consistent, adding safeguards against forged or manipulated payment information. Smart contracts check transaction details against the original payment request, while electronic signatures are 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 designed specifically around blockchain technology. By presenting payments 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, and its latest patent extends that work from stablecoin operations toward the transaction interface used by merchants and consumers. That progression places the company's protected technology at both ends of the payment path: the issuance and management of the stablecoin itself, and the customer-facing interaction where the asset is actually spent.

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: customers can use wallets they already control rather than being required to adopt a proprietary wallet built for the payment platform, and 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 and will connect B-DAX's won-denominated stablecoin, KRW1, with the Insaengnecut payment environment.

Rather than focusing only on the initial transaction, the planned demonstration will test the payment process across multiple stages. Jector said 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. How the system handles the later stages — cancellations, refunds, and settlement — at the Oct. 1 demonstration is the near-term marker for whether the patented flow can function in routine merchant operations.

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.
