India represents Singapore's third-largest tourist market and one of its most significant expatriate communities. In 2024, Singapore welcomed 1.2 million Indian visitors, while approximately 675,000 Indians call Singapore home as residents, professionals, and students. For Singapore merchants, this combined demographic creates a substantial and growing customer base that increasingly expects to pay using India's Unified Payments Interface (UPI), the world's most widely adopted real-time payment system.
UPI has transformed digital payments across India, processing over 10 billion transactions monthly through popular apps like PhonePe, Google Pay, and BHIM. In February 2023, Singapore became the first country to link UPI with its national payment system, PayNow, enabling instant cross-border transactions.
Understanding UPI and Its Singapore Integration
UPI operates as a QR code-based instant payment system connecting directly to users' bank accounts. Unlike card payments or other digital wallets, UPI transactions settle in real time without requiring stored balances or multiple funding sources. Users authenticate payments through their banking app using PINs or biometric verification, making transactions both secure and instantaneous.
The Singapore-India payment linkage allows Indian nationals to use their home banking apps to pay Singapore merchants in Singapore dollars. Currency conversion happens automatically at competitive exchange rates, eliminating forex confusion for customers and settlement complexity for merchants. Through Debia's platform, UPI transactions appear alongside PayNow, card payments, and other e-wallets in one unified dashboard, with settlements processed in SGD.
What Makes UPI Unique?
The phenomenal success of UPI stems from its innovative framework, developed by the National Payments Corporation of India (NPCI) and regulated by the Reserve Bank of India (RBI). Unlike traditional digital wallets, UPI is an interoperable system that allows users to link multiple bank accounts to a single application, using a Virtual Payment Address (VPA) for instant, round-the-clock fund transfers.

This interoperability is key to its dominance, with the UPI platform now serving over 500 million active users and consistently processing transaction volumes exceeding 16 billion monthly in 2024, demonstrating its unparalleled scale and central role in the Indian economy.
The most critical development for Singapore merchants is the PayNow-UPI linkage, a collaboration between the Monetary Authority of Singapore (MAS) and the RBI. Launched in 2023, this linkage creates the world's first such connection to feature cloud-based infrastructure, enabling real-time, cross-border payments between the two nations' fast payment systems.
This bilateral agreement means that when an Indian tourist scans a merchant’s QR code in Singapore, the payment flows directly from their Indian bank account, converting Indian Rupees (INR) to SGD instantly at competitive, transparent rates. This eliminates the need for tourists to carry large amounts of cash or rely on physical card transactions, which can often be cumbersome.

The Strategic Value of UPI for Singapore Merchants
The decision to accept UPI translates directly into significant competitive and operational advantages for Singapore businesses, especially those targeting the dense travel and trade corridor between the two countries.

Direct Access to High-Spending Tourists: India is a crucial pillar of Singapore's tourism recovery and growth. By accepting the payment method trusted by this massive visitor base, merchants are poised to capture a greater share of inbound spending. Visitors who can use their preferred, familiar payment app are proven to spend more and achieve a higher conversion rate at checkout.
Unmatched Transaction Speed and Efficiency: UPI's real-time architecture, facilitated by the PayNow linkage, ensures payments clear in seconds. This speed is vital in high-volume environments like retail stores and busy restaurants, resulting in shorter queues and a vastly improved customer experience, which contributes to higher throughput per hour.
Future-Proofing for Digital Integration: The PayNow-UPI link is a benchmark for cross-border digital payments globally. By integrating UPI, merchants align their business with the future direction of real-time, low-cost international commerce, supported by the highest regulatory bodies in both Singapore and India.
