Yes. Under Settings, Voting, Where votes come from has three answers. Ask for location lets a phone near the venue in, refuses one that is clearly far away, and lets a phone that declines the prompt through as unverified, with the count on your dashboard. Require location sets a distance, and a phone that can’t prove it’s inside shows a QR code any staff member can scan to let that one person vote. It stops the link texted across town, not a fake-location app.
