To set a different card as your primary card, you’ll need to first add it to your account. For step-by-step instructions, check out:
Once you've added the card, follow these steps in your Atome app:
1) Go to "Me", then tap "Payment method".
2) Select the card you want to set as your primary card.
3) Use the toggle to set it as your primary card. Toggle switches are grey when off and green when on.
Every account must have one card marked as "Primary". All payments will be automatically deducted from this card by default.
