It's not the same problem. They block charges over the limit. You can "turn off" a card after you use it. They have "single use" cards that turn off automatically two minutes after the first charge. You can set the spending limit on single use cards or for non-single use cards on a per month basis or per year basis. You can use any billing name and address with the merchant.
