What makes the Quantum+ Credit Card ideal for everyday cashback?

For anyone comparing cashback options, the Quantum+ Credit Card earns its place among the best cashback credit card choices by rewarding spends across categories rather than limiting cashback to a handful of merchants.

Up to 2% cashback on online spends

Every online purchase earns cashback with no minimum spend threshold to get started. Spends above ₹10,000 in a statement cycle earn up to 2% cashback, while spends up to ₹10,000 in the same cycle earn 1% cashback, so your everyday online shopping keeps adding up.

1% cashback on UPI payments via the IDFC FIRST Bank mobile app

Scan and pay at any of the 60 million-plus UPI-enabled merchants through the IDFC FIRST Bank Mobile App and earn 1% cashback on every eligible transaction.

1% cashback on offline spends

Swipe your card at any store and earn 1% cashback on in-store purchases.

Why Quantum+ stands out from other cashback credit cards

A number of cashback cards look attractive on paper until the fine print reveals annual charges or eligibility conditions that rule out first-time applicants. The Quantum+ Credit Card is built differently.

Zero joining and annual fee

The Quantum+ Credit Card is lifetime free, with no joining fee and no annual fee. Every rupee of cashback you earn stays with you.

No income proof required

Since the card is backed by a fixed deposit, you may not need to provide salary slips, ITRs or other income documents. This can make the application simpler for students, homemakers, freelancers and those new to credit.

Your credit limit equals your FD

The Quantum+ Credit Card is backed by a fixed deposit, and your credit limit is set at 100% of the FD value.

Your FD keeps earning interest

Your fixed deposit continues earning interest while your card earns cashback on daily spends, so your money works twice over.

Builds your credit score

Every responsible transaction on the Quantum+ Credit Card contributes to your credit history, helping you qualify for better cards and loans down the line.

How much cashback can you earn every month with Quantum+?

Your monthly cashback depends on how you spend. Online spends above ₹10,000 in a statement cycle earn 2% cashback, UPI payments through the IDFC FIRST Bank app earn 1%, and offline card swipes earn 1%. Here's an illustrative example for someone who splits spending across all three categories in a single statement cycle:

Monthly spend category	Amount	Cashback rate	Cashback earned
Online spends	₹12,000	2%	₹140
UPI payments via IDFC FIRST Bank app	₹3,000	1%	₹30
Offline card swipes	₹2,000	1%	₹20
Total	₹17,000	-	₹290

Since there's no minimum spend requirement to start earning, even modest monthly transactions contribute to your cashback total from the very first statement cycle, while your fixed deposit continues earning interest in parallel.

First-time credit card users looking for a simple, zero-fee starting point
