Getting a credit card in India is not always straightforward. Most banks ask for income proof, a salary slip, or a high CIBIL score. If you are a student, a homemaker, a freelancer, or someone just starting out, that can feel like a dead end.

The IDFC FIRST Bank Quantum+ Credit Card changes that. It is a lifetime free, FD-backed credit card that gives you guaranteed approval, cashback on every eligible spend, and a practical way to build your credit history, all starting with a Fixed Deposit of just ₹5,000.

What is an FD-Backed Credit Card?

An FD-backed credit card is a secured credit card issued against a Fixed Deposit. Instead of your income or credit score, your FD acts as collateral. The bank uses your FD to determine your credit limit, and in return, you get a fully functional credit card.

The key advantage is that approval is guaranteed. Since the bank already has security in the form of your FD, there is no need for income proof, salary slips, or a high CIBIL score. Your FD continues to earn interest as usual, and your credit card works like any other, for online, offline, and UPI payments.

How Does the Quantum+ Credit Card Work?

The Quantum+ Credit Card works on a simple principle. Your Fixed Deposit becomes your credit limit.

You open an FD with IDFC FIRST Bank starting at just ₹5,000. Your FD backs your card, and in return, you receive a Quantum+ Credit Card with a credit limit equal to 100% of your FD value. So, if your FD is ₹10,000, your credit limit is ₹10,000.

Your FD continues to earn interest throughout. You spend on your card, earn cashback, and pay your bill at the end of the cycle. Your FD stays untouched, which means you are earning on both sides simultaneously.

Who is the Quantum+ Credit Card Designed For?

The Quantum+ Credit Card is built for anyone who wants to start their credit journey without the usual barriers.

Students

When you are still studying, getting a credit card can feel impossible. No income, no credit history, no approval. The Quantum+ Credit Card changes that. All you need is a Fixed Deposit of ₹5,000 to get started and begin building your financial profile early.

Homemakers

Managing a household does not always come with a salary slip. But that should not stop you from having financial independence. The Quantum+ Credit Card gives you access to credit on your own terms, with no income proof required.

First Jobbers

You just started earning and want to make the most of it. The Quantum+ Credit Card lets you build a credit score from Day 1, so by the time you need a bigger loan or a premium card, your credit history is already working in your favour.

Freelancers

Irregular income and no ITR can make unsecured credit cards hard to get. If you have savings, you can park them as an FD and get guaranteed access to credit without jumping through hoops.

What Are the Features of the Quantum+ Credit Card?

Lifetime Free

There is no joining fee and no annual fee, so owning the Quantum+ Credit Card costs you absolutely nothing.

Guaranteed Approval

Your approval is based on your FD and nothing else, so it does not matter if you have never had a credit card or do not have a credit score.

FD Starting at Just ₹5,000

The minimum FD required is just ₹5,000, so you do not need a large sum sitting idle to get started.

Personal Accident Cover Worth ₹2 Lakh

A personal accident cover of ₹2,00,000 comes built into your card, so you have that added layer of protection from Day 1.

Lost Card Liability Cover Worth ₹25,000

If your card is ever misplaced, you are covered against unauthorised transactions up to ₹25,000, so you never have to worry about losing money.

How Does the Quantum+ Credit Card Help Build Your Credit Score?

An FD-backed credit card like the Quantum+ Credit Card is one of the most practical ways to build or repair your credit score in India. It works like a standard credit card, and every on-time payment gets reported to CIBIL, helping you build a positive credit history over time.
