A "CC checker" (credit card checker) script is a piece of software designed to verify whether a given credit card number is valid — not necessarily whether it has funds, but often whether it passes basic structural checks (Luhn algorithm, BIN/IIN recognition, expiration date format) or, more dangerously, whether the card can be successfully charged a small amount (e.g., $0.50 or $1.00) through a payment gateway.
