Thailand Unites Indonesia and Vietnam in Digital Payment Surge Joining the Tourist Bill-Shocking Scandal Exposed, So Are Travellers Getting Cheated With Hidden Fees, Dynamic Pricing and QR Code Traps: What You Need to Know

The transformative move toward digital and wallet-based payments across Southeast Asia has brought a wave of convenience and frictionless transactions—but with it comes a growing potential for tourist bill-shock, hidden surcharges and payment-fraud risk. As countries like Thailand, Vietnam and Indonesia accelerate their shift to cash-less societies, mobile wallets, QR codes and mobile-first payment platforms have become dominant modes of transaction for both locals and travellers. At the same time, payment-fraud reports and concerns about transparency in cross-border or tourist-facing payment models are mounting. This article explores the dual reality of the region: the impressive adoption of digital payments on one hand, and the emerging vulnerabilities for foreign visitors who may pay more—or fall victim to scams—under the banner of digital convenience.

The region’s wallet-ecosystem is surging. In Indonesia the QRIS system logged explosive growth—users and merchants soared, with cross-border QR links to Thailand and Singapore emerging. In Vietnam mobile wallet acceptance and merchant infrastructure jumped significantly in 2024, positioning new payment behavior at the heart of the tourism transaction experience. 2C2P+1 Thailand continues to expand its national wallet-infrastructure, influenced by official programs and merchant adoption of QR and app-based payments. chubb.com+1 Tourists arriving in these markets bring expectations of “tap‐and-go” payment convenience. Yet the reality includes a mixture of coverage gaps (many smaller vendors still cash-only), unfamiliar local wallets, and payment environments where surpreaching fees or transaction irregularities can emerge.

One documented risk is surcharges and hidden fees linked to digital payment usage. A travel-payment guide for Southeast Asia notes that while card and mobile payments are increasingly accepted in destinations like Thailand and Vietnam, “plenty of merchants impose surcharges” or guest users may encounter unexpected amounts—especially when payments are denominated in local currencies with large numeric values (e.g., Vietnamese dong) where a simple mistake can lead to overpayment. BCD Travel Further, a payments-industry deep dive reveals that mobile wallet and QR transactions involve multiple layers of cost (merchant processing, cross-border conversion, wallet‐to‐merchant fees) which may translate into higher costs for users, including tourists not familiar with the local ecosystem. 2C2P+1

Another key vulnerability is fraud and scam risk within the digital payment space. A Chubb article on digital payments highlights that Southeast Asia expects a gross transaction value of roughly USD 1.5 trillion by 2025, and underscores the emerging “trust gap” as scam and fraud operations pig-gyback on mobile-wallet growth. chubb.com In Thailand for example, many online payment frauds have been tied to mobile/QR transfers and the central bank has introduced caps and stricter identity verification rules to counter the problem. AP News While not exclusively tourist‐facing, these mechanisms demonstrate how the payment architecture can be manipulated and how foreigners using unfamiliar wallets may be more exposed.

The issue of dynamic pricing or differential charging for foreign tourists via mobile/QR payments remains less documented, yet the structural risk is present. Many payment providers and merchants set different surcharge rules for “card/QR payments” vs cash, or apply premium conversion rates for foreign card users. Although I did not locate a comprehensive study in 2024-2025 that systematically measures how much more tourists pay when using mobile payments in Thailand, Vietnam or Indonesia, travel-payment guides caution that “when making contactless payments in Vietnam … it is very easy to over-pay by a factor of ten or more” if the payment amount is mis‐entered or a foreigner fails to verify the displayed total. BCD Travel For tourists, unfamiliar with dong values, QR app language or hidden merchant fees, the risk of paying more than intended is real.

From a tourist-vulnerability perspective, the combination of factors elevates the risk profile. Visitors may arrive expecting cashless convenience but face local wallets not optimised for foreigners, merchant surcharge policies not clearly disclosed, foreign-currency conversion markups, and increasing QR-fraud threats. Tourist environments (markets, street food vendors, smaller hotels) may support mobile payment but may also retain cash-only options, leading to a mix where “digital payments” might look easier and cheaper—but in practice cost more. A travel-guide source warns that travellers should “always make sure you have cash on you in case you cannot pay by card or mobile payment”. BCD Travel

Regulatory responses in the region show awareness of the problems, but also indicate the complexity of enforcing tourist-friendly payment transparency. For instance, Thailand’s central bank’s decision to cap daily online transfers for new mobile banking users stems from concerns about massive scam losses—over three thousand cases per month and losses in the tens of millions of dollars. AP News While this refers to domestic fraud, it signals how lax or complex payment ecosystems can create vulnerability for anyone—including travellers. Meanwhile, research shows merchants in Vietnam are rapidly embracing mobile wallets and alternative-payment infrastructure, but have varying degrees of readiness, which may translate into inconsistent payment experiences for tourists. 2C2P

Bringing the evidence together: while there is no definitive study showing that tourists in Thailand, Vietnam and Indonesia are systematically exploited via mobile payments (for example via targeted “tourist surcharge” by mobile app), the structural environment indicates strong potential for unexpected hidden payments, fraud risk and payment confusion that can lead to tourists paying more than locals or facing bill-shock. The combination of high mobile-payment adoption, merchant surcharge practices, foreign-currency conversion issues and QR-fraud risk creates a payment ecosystem where tourists must exercise caution.

From a practical viewpoint tourists in these markets might protect themselves by verifying the payment amount before tapping, checking whether a surcharge applies for mobile/QR payment (as opposed to cash), using familiar or widely accepted wallets, and maintaining a cash backup. The travel-payment guide’s explicit warning in Vietnam that “with dong prices including many zeros, it’s easy to over-pay by a factor of ten or more” underscores the need for diligence. BCD Travel In mobile-wallet environments that accept cross-border users (e.g., Indonesia’s QRIS system that supports foreign tourists in some cases) the convenience is real—but so is the need to check exchange rates, conversion fees and surcharge policies.

In conclusion, the surge of digital payments across Southeast Asia’s tourism markets holds enormous promise for convenience and financial inclusion—but it also carries significant risk for tourists. The shift to mobile wallets and QR payments is real and accelerating in countries like Indonesia, Vietnam and Thailand. At the same time, tourists face a payment environment with hidden fees, merchant surcharges, currency conversion complexities and rising fraud risk. Although the evidence does not yet show organized, systematic “tourist-targeted mobile payment exploitation” in 2024-2025, the structural conditions for such exploitation exist and travellers would be wise to approach mobile payments abroad with awareness and caution.
