The cross-border QR Payment Linkage between Thailand and Vietnam has been initiated by the Bank of Thailand and the State Bank of Vietnam, together with participating commercial banks from both countries. This service enables tourists from both countries to make payments for goods and services via mobile banking applications of participating banks by scanning the standardized QR Code of both countries namely Thai QR Payment and VietQR. The service serves as a fast, convenient, and low-cost alternative payment method to enable cross-border transaction and marks an important milestone for ASEAN Payment Connectivity initiative to promote sustainable growth and regional financial development.
