On the iOS app for iPhone and iPad, you can order a sub-card or sub-cards for different teams than your primary card!
First log in to the Fancards app, then find the option that says "Create Another Card."
Next, fill out the card's information and scroll across to find the team and card design you prefer.
Click "Submit", and your sub-card will be created in your Fancards app! The virtual card will be immediately available to add to your Apple Wallet, while the physical card will be mailed to you within 7-10 days.
