The same ticket was scanned twice. Who gets in?
The first scan admits. The second scan flags, and the door team decides by identity, not by shouting.
The first scan holds the entry. The second attempt is flagged to the door team, who check identity against the order and admit the buyer once.
Double scans have three causes and only one is fraud. Screenshots shared between friends. A buyer who forwarded the confirmation mail. Or a copied code. The scanner cannot tell them apart; the door team can, by asking for the order name and an ID.
Decide by identity. The person matching the order name is the buyer; admit them and note the duplicate so the next gate sees it. A guest with a forwarded screenshot and no matching identity waits while the buyer is contacted. Fraud at scale, many copies of one code, means holding the code and calling the organizer, not debating at the gate.
After entry, mark the ticket so re-entry follows the wristband or stamp, not the code. The code did its job at first scan.
