How do Indian payment gateways support one-click payments?

 One-click payments are designed to make checkout faster and smoother by letting customers pay instantly without re-entering card or UPI details every time. In India, this feature is tightly linked to RBI’s card tokenization mandate and UPI AutoPay, ensuring both security and convenience.



How It Works

  1. Card Tokenization

    • When a customer saves their card on a merchant site, the gateway replaces the real card number with a token.

    • During the next transaction, the token is used instead of raw card data.

    • The customer just enters the CVV/OTP (sometimes only OTP) to complete the payment.

  2. UPI AutoPay (One-Click via UPI)

    • Customers authorize a UPI mandate once.

    • Subsequent payments (subscriptions or quick checkouts) are processed with a single click, without fresh authentication each time.

  3. Wallet-Based One-Click

    • Gateways that integrate wallets (like Paytm, PhonePe, or Amazon Pay) allow customers to pay instantly with a saved balance, making checkout a one-click process.

Examples of Indian Gateways Supporting One-Click Payments

  • Razorpay – Offers “Razorpay TokenHQ” for card tokenization and one-click checkout.

  • PayU – Provides one-tap payments for cards and UPI via saved tokens.

  • CCAvenue – Supports stored card tokens and UPI AutoPay for recurring or one-click payments.

  • Instamojo – Focuses on simple one-click payments for small merchants using UPI and wallet integrations.

  • NTT DATA Payment Services India – Supports tokenization and UPI AutoPay, enabling merchants to offer smooth one-click checkout while staying compliant with RBI rules.

Conclusion
Indian payment gateways support one-click payments mainly through tokenization, UPI AutoPay, and wallet integrations, balancing convenience with security. This helps businesses improve conversion rates while keeping customer data safe.

FAQ
Q: Can merchants store card details directly for one-click payments?
A: No. RBI rules prohibit merchants from storing card details. Only gateways and card networks can tokenize cards for secure one-click transactions.

How do transaction charges differ between EDC and POS devices?

Image
 Transaction charges differ between EDC and POS devices mainly based on their functionality, service structure, and the type of payments they support. An EDC machine is primarily focused on processing card payments, so its transaction charges are usually straightforward. These charges typically depend on the mode of payment, such as debit card, credit card, or contactless payments. Since EDC machines do not offer additional business management features, their cost structure is relatively simple, and many providers keep the charges lower to make them accessible for small and medium businesses. On the other hand, POS devices come with more advanced features, including billing, reporting, inventory management, and software integration. Because they handle more data and offer more services, the transaction charges associated with POS machines may sometimes be slightly higher or may include additional service fees depending on the provider’s pricing model. The charges may also vary bas...
