Deck helps you and your friends unlock the best card offers — together.
Everyone holds different credit and debit cards, each with its own discounts and cashback. But when you're about to buy something, you rarely know which friend has the right card to save you money. Deck fixes that.
Add the card types you hold, choose who to share them with, and instantly see which friend's card unlocks an offer at the store you're buying from — then ask them with a tap.
WHAT YOU CAN DO
• Build your deck — add the cards you hold (bank and card type only)
• Share safely — with all your friends, or specific groups you create
• Find a deal — search a merchant or category and see which friends' cards unlock an offer
• Ask instantly — reach the friend who can help over WhatsApp
• Organise friends — make groups like "Family" or "Foodies" and pick members from your contacts
PRIVACY BY DESIGN
Deck only ever stores the card TYPE (issuer and product, e.g. "HDFC Millennia"). We never ask for or store card numbers, CVV, expiry dates, PINs, or any credentials. You choose exactly who can see each card, and you can change or hide it at any time.
HOW IT WORKS
1. Sign in with your phone number
2. Add the cards you hold and pick who they're shared with
3. When buying, search the merchant — Deck shows which friend's card gets you a deal
4. Tap Ask to message them
Save more on every purchase by tapping into the cards your friends already have. Download Deck and never miss an offer again.

Who hunted Deck?
Deck was hunted by Sneha Bharti. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it. Hunters typically write the first comment explaining why a product is worth attention, and their followers are notified the moment they post. Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.
