The digital yuan continues to gain momentum in real-world applications, with a major upgrade announced for Shanghai’s public transportation system. Starting June 28, the “tap to pay” function using digital yuan hard wallets has been expanded to the entire Shanghai Metro network—including all urban and suburban lines. This means commuters and visitors can now simply tap their IC cards, SIM cards, or mobile payment devices equipped with digital yuan hard wallets at any metro gate to pass through quickly and seamlessly.
This move marks a significant milestone in China’s push toward a cashless, digitally integrated society—particularly one that welcomes both domestic users and international visitors seeking frictionless payment experiences.
Seamless Cross-Platform Integration
One of the standout features of this rollout is its interoperability across financial institutions. Passengers using a digital yuan hard wallet issued by any participating bank or service provider can use it across the entire Shanghai Metro system. This cross-institution support ensures broad accessibility and convenience, removing barriers that often come with closed-loop payment ecosystems.

For inbound travelers, especially those unfamiliar with local mobile payment apps like Alipay or WeChat Pay, the digital yuan hard wallet offers a privacy-preserving alternative. These wallets can be easily obtained at self-service kiosks located in airports, train stations, hotels, and border checkpoints. Since they don’t require personal identification or linkage to domestic banking systems, they protect user anonymity while enabling full functionality on public transit.
A Gateway for Global Visitors
Shanghai, as one of China’s primary international gateways, welcomes millions of foreign tourists and business travelers each year. The Maglev Line, which connects Pudong International Airport to the city center, was the first route to pilot this new payment method on June 14—serving as a symbolic "first touchpoint" for many arriving visitors.
The initial trial included support for contactless payments via UnionPay, Visa, MasterCard, American Express, and various forms of digital yuan hard wallets—including physical IC cards, embedded SIM cards, wearable tech (like smartwatches), and phone-based NFC payments (such as mobile Pay services). Even when a smartphone is out of battery or offline, these hardware-backed solutions remain functional thanks to near-field communication (NFC) technology.
Now extended citywide, the system operates on an “entry deduction” model: fare amounts are automatically deducted upon entry based on estimated journey costs, with final adjustments made during exit scanning—a streamlined process designed for speed and efficiency.
With 21 metro lines, 517 stations, and over 896 kilometers of track, Shanghai boasts one of the largest urban rail networks in the world. It handles more than 77% of the city's daily public transit trips. Integrating digital yuan into such a vast infrastructure signals strong institutional confidence in the currency’s reliability and scalability.
Driving Broader Adoption Through Real-World Use Cases
Beyond Shanghai, cities across China are actively expanding digital yuan use cases:
- Zhejiang Province launched a pilot program linking digital yuan to “first-store economy” initiatives—offering incentives for consumers shopping at newly opened retail brands.
- Shandong Province is promoting digital yuan for subsidy disbursements related to consumer electronics and green vehicle purchases.
- National financial authorities have backed Shanghai’s role in cross-border innovation, including participation in the mBridge project—a multilateral central bank digital currency (CBDC) initiative aimed at improving international settlement efficiency.
These developments reflect a strategic effort not only to modernize domestic finance but also to position digital yuan as a tool for global financial inclusion and tourism-friendly infrastructure.
Why Hard Wallets Matter
Among the various forms of digital yuan wallets, hard wallets stand out due to their low entry barrier and wide usability. Unlike software-based wallets that require smartphones and internet connectivity, hard wallets operate independently—making them ideal for:
- Elderly populations less familiar with smartphones
- Students without personal bank accounts
- Foreign travelers avoiding app downloads or data plans
Their adoption in public transport systems like Qingdao Metro, Suzhou buses, and Hainan’s公交 network underscores their growing importance in everyday life.
