Card-on-File vs Direct Debit for Recurring Bills

A stored card can cost more in fees than it earns in rewards, while bank autopay can overdraw checking. US household bills can be pulled from a checking account by ACH debit (the American version of a UK direct debit) or charged to a card the biller keeps on file.
