The company behind Tapdi
Pick the right card.
Tap đi.
“Tap đi” is Vietnamese for “go on, tap.” We build Tapdi so the moment at the till comes with confidence: the right card, the cashback you expect, and no due date forgotten.
Four cards, four rulebooks. Sample cards for illustration.
The moment we design for
Wallet full of cards. Head full of rules.
Every card comes with its own fine print, and nobody remembers it at the till. Tapdi does the remembering, so people can just tap.
- 5% on groceries
- 6% on dining, capped at 200,000₫
- Counts only after 3,000,000₫ spend
- Cap resets on the statement date
- Annual fee waived above a spend target
Our product
One app for the whole life of a card payment.
Tapdi brings each card's rules, caps, fees and due dates into one place. It works from the bank alert emails users choose to forward, and never asks for a bank password.
Available in Vietnamese and English.

Tapdi uses your spending history and each card’s rules to estimate cashback. Results depend on eligibility, caps, and how your bank classifies the transaction; the bank’s statement is the official record.
- Cards ranked for the category you're about to spend in
- Warned before a cashback cap fills up
- Caps run on your statement cycle, not the calendar month
- Suggests the next card worth opening, from your own history
