Carded

IDED

Think of what you might show a bouncer to prove you're old enough—it’s often abbreviated on forms.

"Carded" here is a playful hint for "IDed," since showing an ID card is often called getting "carded." The clue uses the past tense of "card" to suggest the past tense of "ID," turning it into a quick verbal trick. It’s a common crossword move where a word’s alternate meaning (like a physical card vs. the act of checking ID) leads to the answer.
