On April 15, the Taiwan Central Bank released the “Summary Report of the Central Bank Digital Currency (CBDC) External Communication Activities.” With the rapid development of the global digital economy, the Central Bank of Taiwan is actively exploring the application potential of retail central bank digital currency (CBDC). In the ecosystem of a retail CBDC, the wallet architecture design is a key piece of infrastructure that determines whether the policy can be widely adopted. Taiwan’s CBDC is preparing to ensure financial stability and transaction efficiency through a two-tier operating model; in the future, foreign visitors will also be able to open anonymous wallets, and while traveling in Taiwan, make purchases through their CBDC wallets—no need to make change, avoiding the high costs and hassles of cash transactions.
In the retail CBDC plans of most countries, the “Two-Tier System” is commonly adopted. Under this model, the central bank is responsible for issuing the digital currency and maintaining the security of the core ledger; meanwhile, the development, promotion, and day-to-day operation of digital wallets are handled by commercial banks or licensed payment institutions. This public-private sector collaboration framework can not only avoid the operational pressure on the central bank of dealing directly with a large number of retail customers, but can also leverage the market sensitivity of private institutions to provide diversified wallet interfaces and value-added services. In addition, it helps maintain the existing financial intermediation functions of commercial banks, and mitigates potential impacts of digital currency on the traditional financial system.
To balance users’ transaction privacy with anti-money laundering (AML) regulations, Taiwan’s CBDC wallets are expected to introduce a “Tiered KYC” mechanism. This means that the wallet will set different upper limits for holding balances and transaction amounts based on the level of identity verification the user provides. For example, a low-verification wallet that only provides basic contact information may protect privacy for everyday small transactions, but it will face strict amount limits; if users need to make large transfers, they must complete full real-name authentication. This design can both help prevent financial crimes and greatly maximize the coverage of inclusive finance.
For the payment needs of foreign visitors, the flexible wallet architecture of CBDC can significantly reduce friction costs for cross-border payments. Traditionally, foreign visitors find it difficult to open accounts with local banks during short trips and often rely on credit cards or withdrawing physical cash, which involves higher foreign exchange fees. Under the CBDC framework, travelers can use a foreign mobile phone number to activate an anonymous dedicated digital wallet through a dedicated application. This low-threshold account opening process eliminates cumbersome paper-based work, allowing travelers to make purchases immediately in New Taiwan Dollars.
According to the central bank’s preliminary plan, foreign visitors’ wallets may have a balance limit of 30,000 New Taiwan Dollars; if promotion and broad adoption are successful, it will enhance foreign visitors’ sense of experience.
