Several countries around the world have developed their own versions of real-time payment systems similar to India's Unified Payments Interface (UPI). While UPI is a standout due to its user-friendly interface and widespread adoption, here are a few notable systems that are comparable:

1. Faster Payments Service (FPS) – United Kingdom

Launched in 2008, FPS enables near-instant payments between bank accounts in the UK. It allows individuals and businesses to make real-time payments, and many banking apps now integrate this service for mobile transfers.

2. Zelle – United States

Zelle is a U.S.-based real-time payments system that facilitates peer-to-peer (P2P) transactions directly from bank accounts via mobile phones. It's widely used for personal payments and integrates with several major U.S. banks.

3. PIX – Brazil

Introduced by the Central Bank of Brazil in 2020, PIX allows real-time payments between individuals and businesses. It's similar to UPI in its aim to facilitate cashless transactions and increase financial inclusion.

4. PayNow – Singapore

PayNow enables real-time fund transfers between bank accounts in Singapore using mobile numbers or national identification numbers. It is primarily aimed at peer-to-peer payments and integrates QR codes for easier transactions, much like UPI.

5. Swish – Sweden

Swish is a mobile payment system developed by major Swedish banks that allows instant payments via a mobile app. It's used for P2P transfers and is also accepted by merchants and businesses for real-time transactions.

6. PromptPay – Thailand

Part of the National E-Payment Plan, PromptPay allows instant money transfers using just a mobile number or national ID. Like UPI, it aims to make transactions more accessible and boost the cashless economy.

7. InstaPay – Philippines

InstaPay is a real-time payment system in the Philippines that enables quick money transfers between different banks and e-wallets. It is part of the country's push towards digital payments, similar to India's UPI.

8. TIPS (TARGET Instant Payment Settlement) – European Union

Operated by the European Central Bank, TIPS facilitates instant payments in Euros across the EU, allowing real-time transactions between financial institutions.

9. Real-Time Rail (RTR) – Canada

Canada is in the process of launching its real-time payment system, RTR, which will provide a platform for instant payments between individuals and businesses across the country, similar to UPI.

These systems are part of a global trend toward real-time, digital payment solutions that are efficient, secure, and accessible, aimed at reducing dependency on cash and traditional bank transfers. UPI's success, particularly in scalability and inclusion, has become a model for other countries developing their own digital payment frameworks.
