How to redeem reward points on HSBC credit card?

I have accumulated around 10,000 reward points on my HSBC credit card. What is the redemption value in rupees and the best way to use them?

I closed my HDFC card last year. The process took exactly 7 days. They sent a confirmation email and a closure letter by speed post. Tip: pay off the full outstanding and request closure only AFTER the payment reflects. Calling repeatedly with a zero balance is the fastest path.
