AU InstaPay RuPay Credit Card: LTF Fees, UPI Cashback & Benefits
What Is the AU InstaPay RuPay Credit Card?
AU InstaPay is a RuPay credit card designed for UPI merchant payments. AU says cardholders can link the card to supported UPI applications and use it to scan merchant QR codes and pay from the credit line.

UPI Payments With AU InstaPay
The main use case for this card is paying eligible merchants through UPI using the RuPay credit-card rails. AU states that users can scan merchant QR codes through supported UPI applications.
The card is intended for domestic merchant transactions. UPI does not turn the credit card into a general-purpose method for every type of bank transfer; applicable merchant, issuer and UPI rules still apply.
How to link the card
- Register your mobile number in a supported UPI application.
- Select the option to add or link a credit card.
- Select AU Small Finance Bank as the issuer.
- Select the eligible AU RuPay credit card.
- Complete the verification process and set a separate UPI PIN if required.
Cashback
AU currently advertises 1% cashback on UPI transactions in specified categories: departmental stores, dining, pharmacy, grocery and supermarkets.
AU's FAQ states that the transaction must be at least ₹200 and must fall within the applicable merchant-category codes. Therefore, the 1% rate should not be treated as cashback on every UPI transaction.
Fees & Charges
| Charge / benefit | Current information |

| Joining fee | ₹0 |
| Annual fee | ₹0 |

Lifetime free refers to the joining and annual fees. Interest, late-payment charges, cash-advance charges and other applicable charges can still apply. Check AU's latest MITC and fee schedule before relying on any charge figure.
Eligibility
The most important eligibility restriction is straightforward: AU currently states that the InstaPay Credit Card is exclusively available to its existing credit-card holders.
This means the card should not be presented as a universally available LTF credit card for new-to-AU applicants. Approval and issuance remain subject to AU's applicable eligibility rules.
