Infrastructure rails
PromptPay
Real-time retail payment rail — ~22B tx/year
PromptPay (launched 2017) is Thailand's dominant real-time payment rail, processing ~22 billion transactions annually as of FY2024. Peer-to-peer, person-to-business, and government-to-person disbursements run on PromptPay. The $145mobile-number-registered linkage threshold drove near-universal Thai adult adoption within two years of launch.
QR Thai Standard
Interoperable QR payment standard
QR Thai Standard is the national QR code payment specification operated by NITMX, enabling interoperability across all Thai bank apps at merchant point-of-sale. Eliminated per-bank QR fragmentation. Merchants use a single QR; consumers pay from any bank app. Over 8 million merchant QR points as of 2024.
ATM interbank switch
National ATM and card network
NITMX operates the interbank ATM switching infrastructure linking the ATM and EFTPOS networks of all Thai commercial banks. Underpins the domestic debit-card settlement and ATM withdrawal network for ~200 million card transactions monthly.
Cross-border QR
ASEAN, Japan, Korea bilateral linkages
NITMX has established bilateral real-time QR payment linkages with Singapore (PayNow), Cambodia (Bakong), Malaysia (DuitNow), Indonesia (QRIS), Vietnam (VietQR), Japan, and Korea. Cross-border QR tourism transactions are growing as inbound tourists use their home bank apps to pay at Thai merchants.

Key drivers 2025-2026
Volume
PromptPay transaction growth
Thai consumer and business PromptPay adoption continues to grow as physical cash and cheque use decline. Government stimulus disbursements (digital wallet, subsidy programmes) run on PromptPay infrastructure, creating episodic volume spikes that stress-test and normalise rail adoption.
Cross-border
ASEAN QR linkage revenue model
NITMX and BOT are developing a cross-border QR fee-sharing model. As inbound tourism recovers to 30-35 million visitors annually, cross-border QR payment volume from Chinese, Japanese, Korean, and ASEAN tourists represents meaningful incremental transaction fee income for NITMX member banks.
CBDC
Retail CBDC integration readiness
BOT's retail CBDC pilot (Project Inthanon-LionRock) may eventually route through NITMX infrastructure for distribution and interoperability. NITMX's role in retail CBDC architecture is not yet defined but its position as the national payment switch makes it a natural integration layer.
