Best credit card for students and young professionals in India

On the add-on card: yes, the primary cardholder is fully liable for all spends on the add-on. There is no separate credit limit or statement. So only issue it to someone you trust absolutely — spouse, parents. Not friends, not siblings you have money disputes with.

Tip from someone who made this mistake: never max out the credit limit in the first 6 months. Banks track utilisation, and high utilisation right after approval often triggers a credit limit decrease or even an account review.

I've been a customer for 6 years. The biggest upside is the customer service. The biggest downside is the slow mobile app. If you do most banking on the app, test the app at a branch before applying — it's surprisingly old.
