You can make any changes you need to your COIN subscription or payment on the My COIN website if your subscription is hosted on the COIN website. If your subscription is through the Apple iTunes Store or Google Play Store, you will need to edit your payment information on those platforms.
First, always make sure you're logged in to the correct COIN account here:
If you have a COIN premium subscription, and you would like to change your payment method, you may do so here:
Add a card by clicking this box once you are inside. If you need help deleting any old cards on file, please reach out to our support team!
IMPORTANT! Your newly added card may read as (inactive). This means that your card has not yet been used for a scheduled automatic payment for your subscription. None to worry, it does not mean your card is not working! This status will change when it is used for a scheduled automatic payment.
If you would like some help, please email us!
Thanks for being part of COIN! Happy Geomining!
