How to capture leads at a trade show (the 2026 booth playbook)

Trade show lead capture works when three things happen at the booth, not after it: every contact is captured digitally the moment you meet — scan their paper card, or share your QR card so they save you; a note on the conversation is attached at the same time; and the day's contacts reach your CRM before you leave the venue. Badge-scanner rental is optional — an AI card scanner and a QR card capture leads at any booth, hallway or dinner without show hardware.
