You can add a card that is not listed in Stocard by adding it as "Other Card".
We will automatically generate a default logo for all your custom cards in Stocard. However, you can change this default icon by opening the particular card, opening the card menu (the three dots in the top right corner of the card screen) and choosing to "Edit". Now, you have the option to "Add Card Icon" (Android) or "Change Image" (iOS). We would suggest using the card provider's logo so that your custom cards look similar to the cards you added via our database. A front and back picture of your actual loyalty card can then be stored in the "Notes" tab of your card instead (Android) or by scrolling down to the section "Pictures" (iOS).
You are also more than welcome to suggest new cards to be listed in Stocard. Just drop us a note via support@stocardapp.com.
