No-line-of-credit debit card?
Having worked at a financial institution, this is a somewhat simple, two-part solution. 1) The lendor/vendor/financial institution simply turns off the overdraft protection in all its forms. If no funds are available at a pin-presented transaction, the payment is simply declined. No fee, no overdraft, no mess. 2) This sticking point for a recurring transaction, is that merchants such as Netflix, Gold's Gym etc, CHOOSE to allow payments like this, BECAUSE they are assured they are going to get paid by the financial institution. It prevents them from having issues. Only a gift card will not cost you more money than you put in, BUT I know of several institutions, that too many non-payment periods can cause them to cease doing business with you in the future. TL:DR/IMO If you don't want to pay more than you have, gift cards are the way to go. You can re-charge them whenever you choose, and should you run into a problem, simply buy a new card and start over.
