Before purchasing, ask the store what qualifies for a stamp. Joining a programme or opening a card does not award one.
1

Join the programme

Check that the brand appears in your wallet. If not, complete joining first.
2

Make a qualifying purchase

Follow the merchant’s published programme rules.
3

Show your Kardy QR

Present your code so authorised staff can record the purchase at the correct outlet.
4

Wait for confirmation

Staff review your membership and use Slide to add stamp, then wait for Stamp added. You do not need to prepare a reward QR to earn a stamp. Refresh your card to see the updated progress. See the approval tutorial and rollout note if your screen differs.
Done when: the staff result confirms the stamp and your current card reflects the updated balance. Do not treat a disconnected screen as proof that nothing saved.

​
Stamp not showing?

  1. Ask the employee to confirm they finished adding the stamp and saw the success message. Scanning your QR alone does not add a stamp.
  2. Open your Kardy wallet with the account that joined the programme and check the correct business’s card.
  3. Connect to the internet and choose Refresh wallet. If the button is not available in your version, reload the page instead.
  4. If the balance is still wrong after a successful refresh, ask the store to check the original transaction in your membership’s activity before submitting again.
A delayed display does not mean a stamp was lost. Refreshing only checks your progress; it does not issue another stamp. Keep the business, outlet, approximate visit time and any error message for Support. Never send your password, verification code or private QR.

Why an open card may take time to update

The updated browser wallet checks after one minute, then slows to two minutes and finally every five minutes when nothing changes. A new stamp may take up to five minutes to appear automatically when checks succeed. Checks pause while Kardy is hidden or your device is offline. Returning to the wallet or reconnecting triggers a check; closely repeated checks are combined. Refresh wallet lets you check without waiting for the next automatic update. If it fails, reconnect and retry.
The reduced-check schedule and Refresh wallet button are pending production rollout. Until available, reload your wallet page while online.
This applies to Kardy in your browser or installed home-screen app, not screenshots or saved Apple Wallet/Google Wallet passes. Native passes have separate update timing; see saved wallet passes. Next: Claim a reward. Joined through an invite? Check referral qualification.
