Zero-Floor Limit
Drop dat credit charge to the floor.
A floor limit is the line drawn in the sand where, if a credit or debit transaction is above that line, you need authorization. Only mega-purchases need this kind of authorization, really. Authorization is given from the credit or debit card issuer.
When there’s a zero-floor limit, that moves the line in the sand alllll the way down to your feet. Any transaction you make requires authorization, even measly ones.
A zero-floor limit is often used on the magical world of the internet, when there’s no face-to-face happening with you and the seller of the things you’re buying. The seller’s financial transactions are checked, as well as some checks on due diligence warnings. This is to protect you from fraud. Cool? Cool.
