Share a loyalty card with anyone
The gym card you share with your partner, the shop card your mum uses too, the company card for your colleagues: with Kardpal you send it by email and the other person finds it in their app.
How to send it
Open the card, tap "Share" and type the recipient's email. They get a request under Incoming requests in the app and can accept it, decline it or block the sender.
What you need
The sender needs Premium and a verified email. The recipient only needs a free account.
One card, two phones
If you change the code, the change reaches the other person too. Name, colour and favourite are personal, so they can call it "Sam's gym" without touching your copy.
Revoking access
The Share screen shows who has the card and whether a request is still pending. Tap "Revoke" and the card disappears from their phone. The recipient can also remove it from their account at any time.
For the whole family
If it's more than one or two people, a family group is easier: share once and the card reaches every member.
