# Proof Of Presence Event Check-In When attending an event, you can automatically verify your proof of presence on-chain and issue a badge to your passport. Earn more trust, bounties, and important responsibilities within the community. To do so, at the scheduled time of the event, scan the event QR code and enter the PIN shared with invitees by the founder. The QR Code updates every 30 seconds When an attendee scans the QR code and enters the PIN, a proof of presence badge will automatically be issued on the attendee's passport. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
