Editing and Deleting Cards
How to Edit a Card
Tap on the card you want to edit, tap "Edit" at the top right, make your changes (update card number, add/change custom label, change color for custom cards), then tap Save.
Note: If a card was originally scanned, editing the card number won't actually change the barcode. The original scanned barcode is preserved. This protects you from accidentally breaking in-store scanning.
How to Delete a Card
Tap on the card, tap "Edit", scroll to the bottom, tap "Delete Card", then confirm deletion.
Warning: Deleted cards are permanently removed from your device unless you have a backup!
