Use the merchant-specific link your friend shared, not a general invitation to Kardy. An existing membership cannot be referred retroactively.
1

Open the invite

Check that the link opens the intended merchant’s join page.
2

Sign in and verify

Use your existing Kardy account or create one if needed. Complete email verification and return to the joining flow.
3

Finish joining

Complete the merchant’s join action. Referral details are retained through sign-in and verification.
4

Make your first qualifying purchase

Show your QR and let authorised staff issue your first actual stamp. The server checks the referral requirements at that point.
Done when: your new membership is visible. Joining alone earns no bonus; after the qualifying purchase, check Invites you joined. Read the qualification rules before expecting a bonus. Both members’ account and membership requirements must already be met at the first staff-issued stamp; a later visit does not fix qualification retroactively.
