Report: mobile wallets became the most widely used payment method in 2019, 2.8B wallets were in use by the end of 2020; SE Asia is the fastest growing region

Context & Ripple Effects
The Boku data caps a decade-long arc that started with mobile payments in China reaching $5.5T in a single year — a scale the US was nowhere near — driven by QR-code adoption and super-app ecosystems built by Alibaba and Tencent. What began as a Chinese anomaly is now the global default: wallets passed every other payment method in 2019, before the pandemic accelerated contactless habits.
First-order effects
- Southeast Asia becomes the battleground market for wallet operators, since it combines the fastest growth rate with populations still converting from cash — first-mover share there compounds fastest.
- Card networks and banks lose their position as the default consumer payment rail at exactly the moment wallet volume makes wallet-side fees and data access strategically valuable.
Second-order effects
- Cash-handling infrastructure across Asia faces shrinking utilization, consistent with Worldpay's projection of cash falling from 49% of Asian transactions in 2019 toward 14% by 2027 on QR-code adoption — pressuring ATM operators and cash-in-transit firms.
- Western wallet players like Apple Pay, which had reached only about 5% of global card transactions, face pressure to close the gap with the QR-based models that dominate emerging-market usage rather than relying on NFC handset penetration alone.
Third-order effects
- If wallets are the most-used method globally, whoever controls the wallet controls the customer relationship and transaction data — the 'wallet as permission layer' dynamic that Chinese platforms demonstrated, now spreading to SE Asia and eventually Western markets.
- Regulators will increasingly treat dominant wallet operators as financial-system chokepoints, extending the scrutiny applied to China's duopoly model to whichever players consolidate each regional market.
The trend: Payments are consolidating around smartphone wallets as the global default rail, with Southeast Asia replacing China as the fastest-moving proof point.
