# Invite a friend

> Share a merchant invite, track friends who join, and understand when referral stamps qualify.

## Share a merchant invite

Open a membership card in the Kardy wallet. If the merchant has enabled referrals,
**Bring a friend** includes **Get my invite link**. Copy that link and share it with
your friend. It opens that merchant's join page and retains the referral through
sign-in and verification. The same member can reuse their link for different friends.

The general **Share an invite** button invites someone to Kardy. Use the invite
inside the merchant's card for that merchant's referral rewards.

Creating or copying a link does not earn stamps. A friend must complete joining
through it; an existing membership cannot be referred retroactively.

**Done when:** your friend has received the correct merchant invite link. Joining and earning the bonus happen later.

## When bonus stamps qualify

Joining alone earns nothing. The friend's first qualifying purchase and first
staff-issued stamp trigger the checks for both members. Read the [qualification
rules](/features/referrals#what-qualifies) before promising a bonus.

## Track friends

Follow [Track referral rewards](/customer-journey/track-referrals) to check joining,
qualification and awarded stamps. Send your friend the [joining walkthrough](/customer-journey/join-referral)
if they need help completing the invite.

For merchant controls, see [Referral rewards](/features/referrals). Signup-outlet
attribution is separate from referral qualification; see [joining](/customer-journey/join).
