Transacting with Indian-Origin Fintech

Saurin Chauhan — Sat, 20 Jun 2026 07:38:57 +0000

A few days ago, I was browsing through an online bookstore to purchase some books. While placing the order, something remarkable struck me — every major technology I used in the process was of Indian origin.

This realization inspired me to reflect on how far India has come in building its own robust digital ecosystem, especially when it comes to digital payments.

Let me take you through the step-by-step journey of that simple online order and unpack the fully Indian tech stack powering it.

The Bookstore and the Order Process

I visited the online Bookstore, a revered Indian publisher, and went through the usual purchase steps:

Add to Cart – Selected a few books.
Proceed to Payment – Chose UPI as the method.
Payment Gateway – Redirected to Paytm, an Indian company.
Payment Made via PhonePe – A UPI-based payment app, also made in India.
Linked with RuPay Credit Card – A card issued by HDFC Bank, using India’s domestic card network.
Delivery by Indian Speed Post – The trusted, government-operated logistics service.

From discovery to doorstep, everything was powered by Indian innovations.

The Game-Changer: UPI – India’s Real-Time Payment System

The star of this transaction was the Unified Payments Interface (UPI). Launched by the National Payments Corporation of India (NPCI), UPI has completely revolutionized how Indians make digital transactions.

Instead of entering long card details or OTPs, UPI simplifies the entire process:

Link your mobile number with your bank account.
Scan a QR code or enter a UPI ID.
Authorize with a PIN – and it’s done, instantly.

Global Comparison: Real-Time Payment Volumes (2023)

Country Annual Transactions (Billion) % of Global Real-Time Payments

Country	Annual Transactions(Billion)	% of Gloabal Real-time Payments
🇮🇳 India	129.3	49%
🇧🇷 Brazil	37.4	14%
🇹🇭 Thailand	21.3	8%
🇨🇳 China	18.6	7%
🇰🇷 South Korea	8.0	3%

India alone handles nearly half of the world’s real-time digital transactions!

RuPay – India’s Own Credit Card Network

Another part of this journey was using a RuPay credit card, issued by HDFC Bank. Launched in 2012, RuPay is India’s answer to global card networks like VISA and Mastercard.

Only a handful of countries have their own credit card networks apart from USA:

🇨🇳 China – UnionPay
🇯🇵 Japan – JCB
🇰🇷 South Korea – BC Card
🇹🇷 Turkey – Troy
🇳🇬 Nigeria – Verve
🇮🇳 India – RuPay

In 2022, RuPay became even more versatile — now you can link RuPay cards with UPI, allowing you to scan QR codes and pay directly from your credit card via UPI apps like PhonePe.

The Bank Behind the Card

The credit card I used was issued by HDFC Bank, one of India’s most prominent private banks. It supports UPI-linked RuPay credit cards, enabling a unified payment experience without switching between multiple apps or cards.

Payment Gateway: Made in India

The transaction was securely routed through Paytm’s payment gateway, another made-in-India solution, widely trusted by Indian merchants and users.

In other cases, you might also encounter Billdesk, another Indian-origin gateway that’s been part of India's digital payment story for over two decades.

The UPI App I Used: PhonePe

My go-to app for UPI transactions is PhonePe, one of India’s leading digital payment apps built on top of the UPI stack. It offers instant payments, bill splits, and supports RuPay credit card linking too.

Communication: Powered by Zoho Mail

Even the email I used to sign up and receive order confirmations was powered by Zoho Mail—a secure and privacy-focused email service offered by Zoho Corporation, an Indian multinational tech company headquartered in Chennai.

Zoho has made a global name for itself with its suite of SaaS products, serving millions of users in over 180 countries. What sets Zoho apart is its privacy-first approach and its commitment to keeping data hosted in India for Indian users. With Zoho Mail, I not only got a smooth and professional email experience, but I also continued the streak of using Indian-origin technology at every step.

The Final Leg – Indian Speed Post Delivery

And finally, the books were delivered by India Post’s Speed Post service. Affordable, efficient, and widespread — a fitting close to this "Made-in-India" experience.

India’s Digital Self-Reliance in Action

What started as a simple book purchase turned out to be a powerful reminder of how far India has come in building a truly indigenous digital infrastructure.

Every layer of the experience — from browsing and payment to logistics — was powered by Indian innovation:

UPI: Seamlessly enabled real-time payments, putting India at the forefront of global fintech.
RuPay: Provided a secure credit card network, proudly made for and by India.
PhonePe: Offered a smooth user experience for scanning and paying through UPI.
Paytm: Acted as the payment gateway, connecting merchants and customers with ease.
HDFC Bank: Backed the transaction as one of India’s most trusted banking institutions.
Zoho Mail: Indian email and communication platform
Indian Speed Post: Closed the loop with reliable last-mile delivery.

In a world where digital infrastructure is often dominated by global giants, India has carved its own path — and is now leading it. UPI alone handles more real-time payments than any other system globally, and the ecosystem around it — including RuPay, Indian fintech platforms, and postal logistics — is thriving.

This was not just a smooth transaction. It was a silent but profound display of India’s digital sovereignty, innovation, and execution at scale.

The journey may have started with a few books in a cart, but it ended with a deeper appreciation for the world-class, homegrown digital backbone that powers everyday life in India.

And that, in itself, is a story worth sharing.
