Events allows you to make a wave of tickets for an event, each ticket is in the form of a unique QRcode, which the user presents at registration. Events comes with a shareable ticket scanner, which can be used to register attendees.
You can experiment with Events on lnbits.com, although LNbits should really be run locally, which we make it easy to do as well.
