Payment System and QR Code Utilization

YU Token improves the accessibility of blockchain payments through a QR code-based payment system. QR code payments are faster, more secure, and more cost-effective than traditional credit card and cash payment systems.

1) QR Code-Based Payment Method

• Users launch the YU Token-compatible mobile web app and scan the QR code, which automatically activates the payment window.

• The payment amount is auto-filled, and users simply confirm the transaction to complete the payment.

• Transaction data is recorded on the blockchain, preventing manipulation and duplicate payments.

2) Advantages of QR Code Payments

• No POS (Point of Sale) terminal required → Small businesses can accept payments with just a QR code, eliminating additional costs.

• Faster transaction speed → Unlike credit card payments, no approval process is needed, and transactions are instantly processed via Smart Contracts.

• Offline functionality → Even in areas with unstable internet connections, transactions can be processed using a pre-stored QR code.
