When you enroll a card with the app we send the card number directly from your phone to the card network (Visa, MasterCard, Amex) and they enroll it. They then notify us that your card was enrolled (they don't send us the card number itself).
When you attempt to add a card, it's possible that the card network will reject it, and the messaging returned as to why can be somewhat vague for security purposes. Here are some reasons that may result in your card being rejected:
- Your card is already enrolled. This often happens when two people share a card. It also often happens when you already have an account (for example, you signed up a month or two and then signed up again accidentally).
- If your enrolled card has expired and you try to enroll a new card with the same card number, your new card will be rejected. Once you remove your expired card from your account, you will be able to enroll your new card.
- Your card is not supported. We do not currently accept Discover cards. Some Visa, MasterCard, and Amex cards may be rejected if they are pre-paid, corporate, or issued outside the US. This isn't up to us; it's the policies of the card networks.
As always, feel free to contact our support staff. We may be able to help you figure out why your card isn't working.
