Digital RMB, officially known as the digital renminbi or e-CNY, is a groundbreaking innovation in China’s financial infrastructure. Issued by the People's Bank of China (PBOC), it represents the digital form of the nation’s legal tender and is designed to modernize retail payments, enhance financial inclusion, and strengthen monetary policy efficiency. As one of the most advanced central bank digital currency (CBDC) initiatives globally, digital RMB combines cutting-edge technology with practical applications across everyday life—from transportation and healthcare to education and cross-border transactions.
This comprehensive guide explores the development, features, use cases, and broader implications of digital RMB, offering readers an in-depth understanding of its role in shaping the future of money.
Origins and Development of Digital RMB
The journey of digital RMB began in 2014 when the PBOC established a dedicated research team to study the framework for a central bank-issued digital currency. By 2016, China had developed its first prototype and founded the Digital Currency Research Institute. The system was built on key design principles: a two-tier operational model, M0 classification (equivalent to cash), loose coupling with bank accounts, and controllable anonymity.
The core architecture revolves around “one currency, two libraries, three centers”:
- One Currency: Refers to the central bank digital currency itself.
- Two Libraries: The central bank’s issuance vault and commercial banks’ digital currency storage.
- Three Centers: Authentication Center (identity management), Registration Center (ownership tracking), and Big Data Analysis Center (transaction monitoring).
Pilot testing officially launched at the end of 2019 in Shenzhen, Suzhou, Xiong’an, Chengdu, and Beijing’s Winter Olympics venues. By October 2020, six additional cities—including Shanghai, Hainan, and Xi’an—were added to the trial list.

Expansion Through Pilot Phases
First Wave: Urban Testing Grounds
Initial pilots focused on urban consumer scenarios such as dining, shopping, and public transit. In December 2020, Beijing introduced digital RMB at subway stations and Daxing Airport, allowing users—including Olympic skating champion Shen Xue—to pay via wearable devices like smart gloves using NFC "tap-to-pay" functionality.
Second Wave: Broadening Use Cases
By 2021, pilot programs expanded into healthcare, government services, and salary disbursements. Shanghai’s Tongren Hospital implemented a card-based hard wallet that enabled doctors to make offline payments without smartphones. Meanwhile, Hangzhou became the first city where digital RMB could be used to purchase metro tickets directly through the official app.
In July 2021, the pilot scope grew to “10+1” regions—ten major cities plus the Winter Olympics zone. By October, over 3.5 million pilot scenarios had been activated nationwide, with more than 123 million personal wallets opened and transaction volumes reaching approximately 56 billion yuan.
Third Wave: Institutional Integration
2022 marked a turning point with deeper integration into institutional systems:
- Taxes: Hainan Steel Group completed China’s first large-scale tax payment using digital RMB.
- Finance: Construction Bank launched理财 services allowing users to buy wealth management products with e-CNY.
- Transportation: Guangzhou became the first city to enable digital RMB QR code payments on buses.
- Real Estate: Suzhou enabled online payment of property registration fees via digital RMB—the first such application nationwide.
By mid-2022, digital RMB was officially listed in M0 monetary supply statistics, affirming its status as legal tender.
Fourth Wave: Nationwide Scaling
As of late 2022, digital RMB expanded to 17 provincial-level regions. Major milestones included:
- Cross-platform compatibility: Integration with Alipay and WeChat Pay.
- Salary disbursements: Chongqing’s Fuling District executed the city’s first digital RMB payroll.
- Public services: Users could pay utility bills via China Unicom’s app—the first online platform to support direct e-CNY app invocation.
By June 2023, Shenzhen alone had over 35.94 million wallets and more than 2.1 million merchants accepting digital RMB.
Core Features and Technical Design
Digital RMB is engineered for security, accessibility, and versatility. Its defining characteristics include:
Dual-Layer Operation Model
The PBOC issues digital RMB to designated commercial banks (e.g., ICBC, CCB), which then distribute it to the public. This model maintains central control while leveraging existing financial infrastructure.
Controllable Anonymity
While transactions are traceable by authorities for anti-money laundering purposes, small-value payments remain anonymous—balancing privacy with regulatory compliance.
Offline Functionality
Unlike traditional mobile payments, digital RMB supports offline transactions via NFC or QR codes—even when devices are powered off or disconnected from networks.
Smart Contracts
Built-in programmability enables conditional payments. For example, in Shenzhen’s education prepayment platform, funds are released per class attended—protecting consumers from fraud.
Hardware Wallets
Physical cards, wearables, and SIM-based wallets cater to seniors, tourists, and those without smartphones. In November 2024, Shenzhen unveiled a 1mm-thin visual card wallet with an e-ink display showing balance and dynamic QR codes.
Real-World Applications Across Sectors
Transportation
Digital RMB is now accepted across multiple transit systems:
- Beijing: Full subway network supports e-CNY刷卡过闸.
- Shanghai: All metro lines allow card and hard wallet tap-ins.
- Qingdao: First city to deploy delayed deduction mode, enabling entry even with zero balance.

Healthcare
Hospitals in Guangdong and Shanghai accept digital RMB for registration, diagnostics, and medicine purchases. Patients can use both soft apps and hard cards—ideal for elderly users unfamiliar with smartphones.
Education
Shenzhen pioneered a smart contract-based prepayment system for tutoring institutions. Funds are automatically released only after classes are delivered—reducing risks of business closures or fund misappropriation.
Government Services
From tax payments to subsidies:
- Fujian processed China’s first digital RMB customs duty refund.
- Tianjin disbursed employment assistance funds via e-CNY.
- Xiong’an completed the nation’s first fiscal fund transfer using digital RMB.
Digital RMB vs. Alipay & WeChat Pay
| Feature | Digital RMB | Alipay / WeChat Pay |
|---|---|---|
| Legal Tender Status | Yes (state-backed) | No (private wallets) |
| Offline Payments | Supported | Not supported |
| Merchant Fees | None | Typically charged |
| Settlement Speed | Instant ("payment is settlement") | May involve delays |
| Refusal by Merchants | Illegal once fully rolled out | Permitted |
This distinction ensures that digital RMB serves as a foundational payment layer—complementary rather than competitive—to existing platforms.
International Expansion and Cross-Border Use
China is actively exploring international use cases:
- mCBDC Bridge: A multilateral project with BIS, Hong Kong, Thailand, UAE testing cross-border trade settlements.
- Singapore Pilot: Joint initiative allowing travelers to spend e-CNY locally.
- Hong Kong Testing: HKMA collaborating with PBOC on cross-border remittance trials.
- Oil Trade: First crude oil transaction settled in digital RMB completed in October 2023.
These efforts align with broader goals of enhancing RMB internationalization and reducing reliance on SWIFT.
