This feature is only available with the Growth and Ultimate plan.
Replace the default field "Stamps Required Until Next Reward" on your digital stamp card with a custom field. For example:
1 - Go to your card design and click on 'Custom'.
2 - Select the field you want to replace the default one with. These are the fields you have chosen to collect from customers when they sign up.
3 - Replace the original label text ("STAMPS REQUIRED UNTIL NEXT REWARD") with what you want. For example, "Name", "Member Name", "First Name". You can preview this on the right hand side.
Here's what your new card will look like.
