Ask How prevent handle expired credit cards for recurring memberships?

[SuperAffiliateX]

I run a membership site with recurring payments but I'm worried about expired credit cards. What happens when a member's card expires? Do payments just fail, or is there a way to handle it smoothly? I don't want members to lose access without warning. Should I send reminders, or do payment processors handle that automatically? I also want to make it easy for members to update their payment details. If you manage a membership site, how do you prevent issues with expired credit cards?
