Why does Infinia say 16.5%?
That number is a ceiling on eligible SmartBuy spend for some HDFC cards — not the return you get on every swipe. Here’s the short version.
₹10,000 flight: direct vs portal
Example- Buy the flight on the airline site with the card → you earn at the card’s everyday / base rate for that category (often far below the headline).
- Buy the same ₹10,000 flight through SmartBuy (when the booking is eligible) → the card may credit accelerated points under SmartBuy rules — the path behind rates like “up to 16.5%”.
- Same merchant, different checkout path. SmartBuy changes the reward rules for eligible purchases — not the merchant you buy from.
What SmartBuy is
Mechanics- HDFC’s rewards / shopping portal: you complete eligible purchases through it so the bank can apply portal earn rules.
- Rates, categories, and caps are product-specific — Infinia’s SmartBuy story is not universal across every HDFC card.
- Merchants and offers on the portal change; verify the live catalogue and your card’s rewards schedule before assuming a rate.
How Money Matters values rewards
MethodologyMoney Matters separates guaranteed value (the conservative redemption almost everyone achieves) from potential value (the higher value possible via reward-point transfers or portal spend). Rankings always use the guaranteed value. The higher value is shown as “up to” so you understand the card’s ceiling — not because it’s guaranteed.
Two ways that ceiling can show up — same upside methodology, different mechanism:
- Point transfers — change who values the points (partner miles/hotels vs bank catalogue).
- SmartBuy (and similar portals) — change the earn rate for a specific purchase route.
