Badge scans reward volume over quality and tell you how busy a booth was, not whether you built relationships worth pursuing. Scanning a badge takes two seconds and produces a number that looks like progress in a report, but most scans convert to nothing. A stack of hundreds of scans frequently turns into a handful of real conversations and zero deals. Tracking qualified conversations, meetings booked, accounts re-engaged, and pipeline influenced gives a far more honest measure of whether a show worked.
