One of the many ways that we protect your information is by not storing any of your personal information on the Pay With GasBuddy card, which helps to protect against increased card skimmer activity. This means that your banking information is not stored on your card, nor can it be retrieved through your card. As such, closing down/freezing your linked checking account is not necessary. For more information on how we keep your banking information secure, please read our article on DWOLLA, the payment platform we use to securely process transactions.
