Best add-on credit card for spouse in India

The customer care experience matters more than people think. I've had two cards with similar rewards, and the one from the bank with better support saved me ₹18,000 when there was a merchant dispute. Don't underestimate this.

The 'minimum due' trap is real. Banks love it because they charge ~36-42% interest on the carried-forward amount. If you can't pay the full bill this month, pay at least 50% — anything below that and the interest eats the rewards of the next 6 months.

I was worried about the high joining fee but the welcome benefit voucher was credited within 30 days of crossing the spend threshold. Net cost: zero. The trick is to time your application so that you make a big purchase (appliance, travel booking) in the first 45 days.

Dispute process that worked for me: I called customer care within 24 hours, raised a dispute via the netbanking portal (uploading the receipt showing I never visited the merchant), and got a provisional credit in 5 working days. Permanent credit came after the bank's investigation in about 30 days.

Honestly, the annual fee is on the higher side. But if you spend consistently on the accelerated categories, the cashback more than offsets it. I did the maths on my own statement last year and came out ahead by about ₹3,200.

I've held this card for 3 years. Quick reality check: the welcome benefit is good, the first-year fee waiver is easy, but from year 2 onwards you really have to work for the milestone benefits. Don't keep it if your monthly spend drops below the milestone threshold.
