This is not the kind of experience that we want you to have, @RangerZ.

Thanks for taking the time to bring this to our attention. We will use the feedback to make us better. 

When processing a sales receipt, if you select to Use this credit card in the future your customer's credit card will be saved. Then, next time you process sales receipts for this customer, you no longer need to enter their payment information.

I understand that you’d like to let your customers only have the option to pay you using the card that you set in their profile. However, they still need to re-enter their credit card information when processing their payment. The option to set it as default is currently unavailable. 

Let me know if you still have questions. I'm always here to answer them for you. Have a great rest of the day!
