Using the card without a wallet

Customers don't have to add the card to a wallet. Their card also lives in the browser on their phone.

1. Stamps still work

   Tapping the NFC opens their card in the browser and adds the stamp, the same as for wallet users. The card page also shows a QR code that staff can scan to stamp.

2. It belongs to that phone

   The card is linked to the browser it was created in. Clearing the browser's data, or using a different browser, means the card has to be brought back with their email.

3. Getting it back

   On the join page, "Already have a card? Get it back" emails a link that restores the card and all its stamps. See A customer has a new phone.
