Consider the following countries:

How many countries amongst the above are there other than India where international merchant payments are accepted under UPI?

Answer: (b) Only three

Unified Payments Interface or UPI is a real-time payment system developed by the National Payments Corporation of India (NPCI) that enables instant money transfers between two bank accounts using a mobile platform.
Launched in 2016, UPI revolutionised the digital payments landscape by allowing users to transfer funds instantly, 24/7, through mobile apps using just a Virtual Payment Address (VPA), which negates the need to share sensitive bank details.
As of now, UPI (Unified Payments Interface) is accepted for international merchant payments in the following countries other than India:
1. United Arab Emirates (UAE)
2. France
3. Singapore
4. Sri Lanka
5. Mauritius
6. Bhutan
7. Nepal
Hence, among the countries mentioned in the question, only three—the United Arab Emirates, France, and Singapore—officially support UPI for international merchant payments. Germany and Bangladesh do not currently have UPI integration.
NRIs: Non-Resident Indians (NRIs) in countries like Australia, Canada, France, Hong Kong, Malaysia, Oman, Qatar, Saudi Arabia, Singapore, UAE, UK, and USA can use UPI to make INR transactions in India through their registered overseas mobile numbers.
Foreign tourists: Tourists visiting India can use UPI through the “UPI One World” service, which requires full KYC verification with their passport and valid visa.
