How to convert a HDFC Bank credit card purchase to EMI?

On credit limit increase: most banks auto-review every 6 months. If you use 30-70% of the limit and pay in full, you'll get an automatic increase. Don't call and ask for it explicitly — banks take it as a sign of credit hunger and sometimes lower the limit instead.

Credit score impact: each hard inquiry (which happens on card application) drops your score by 5-15 points temporarily. Applying for 3 cards in 2 months is fine IF you get all 3 approved. If 2 get rejected, you've taken a hit with nothing to show for it. Apply smart, not fast.
