Step 1 of 8: Checkout

You're about to pay.

A ₹2,480 grocery order, delivery in 18 minutes. Three cards in your wallet. One of them pays you back more than the others, and the difference adds up over a year.

Step 2 of 8: Screenshot

Take a screenshot.

The same way you always do. No new habit, nothing running in the background, no reading of other apps.

Step 3 of 8: Share

Share it to One Good Tap.

From the screenshot preview or your gallery, tap Share and pick One Good Tap. You choose exactly which image it sees.

Step 4 of 8: Read on your phone

It finds what you actually pay.

Text recognition runs on your phone. It looks for words like "To pay" and "Order total", and skips MRP and "You saved". It never just grabs the biggest number.

Anything that looks like a card number, CVV or OTP is dropped before reading. The screenshot is deleted right after.

Step 5 of 8: Confirm

Check it in one look.

Merchant and amount, ready to confirm. If it isn't sure, it asks instead of guessing. You can always type it in yourself.

Step 6 of 8: Compare

Every card, same maths.

A deterministic engine applies each card's published rules to this purchase: rates, exclusions, caps per statement cycle and what a point is really worth. Money is counted in whole paise.

HDFC Millennia and ICICI Rubyx show no estimate here because One Good Tap hasn't checked their rules yet. It never fills the gap with a guess.

Step 7 of 8: Answer

One clear answer.

The best card, the estimated benefit and one line on why. The breakdown and the other cards are there if you want them.

If something is unknown, like how much of a monthly cap you've used, it says so plainly.

Step 8 of 8: Pay

Go back and pay.

You pay in the shop's own app, with the card you picked. One Good Tap never sees your card details and never touches the payment.

Scroll

In a shop it works the same way. Ask One Good Tap, then tap the right card.

One good tap.

The right card, chosen before you paid. Every time.

Every answer says how sure it is.

Green only appears when a rule was checked against the bank's own terms. Anything less is labelled in words.

  • Verified
    Checked against the source

    The rule matches the bank's published terms. You can see the document and the date it was checked.

  • Estimate
    One thing is unknown

    Something only you or your bank knows is missing, like how much of a monthly cap you've used. It names exactly what.

  • Not enough information
    No number made up

    If a card has no checked rule for this kind of purchase, it says so.

Where the rules come from

Card benefits change often and sit inside long PDFs. Every rule takes the same path before it can affect an answer.

  1. Bank documentsMITC and reward terms, fetched only from the bank's own website.
  2. Facts pulled outRates, caps and exclusions, each with the sentence it came from.
  3. CheckedEvery quote and number is matched against the document.
  4. Signed offA person reviews it before it is published, with its source and date.
  5. CalculatedThe engine applies it to your purchase, in whole paise.

No language model decides a reward rate, a cap or whether a purchase qualifies. The same purchase always gets the same answer.

No screenshot? Type it in.

At a kirana counter, a restaurant or a petrol pump, pick the kind of shop and enter the amount. Card or UPI, the answer comes the same way.
