The cross-border payment linkage between Thailand and Indonesia connects national payment infrastructures of Thailand and Indonesia to enable cross-border QR payments. Tourists and merchants in both countries can make and accept instant cross-border QR payments. Thai tourists may use their mobile payment applications to scan QRIS (Quick Response Code Indonesian Standard), the standardized QR code in Indonesia, to make payments to merchants in Indonesia. Likewise, Indonesian tourists may use their mobile payment applications to scan Thai QR Codes to pay for goods and services at merchants in Thailand. The linkage marks a key milestone in the ASEAN Payment Connectivity initiative, aiming to promote regional financial integration.
