Etymology: "Cardless" is a plain formation: the noun "card" with the suffix "-less," meaning "without." Its sense follows directly from that pairing, so something cardless has no card, whether a playing card, a paper card or a card in the sense of a plastic payment or identification card. The word is a piecewise doublet of "chartless," meaning the two words share the same pattern of a base noun plus "-less," each formed separately from its own base, with "chart" in place of "card."
