With Berrly Events you can create public events where people can register and book tickets.
On the day of the event you can set up a ticket control to control the access of members or non-members who want to access it.

Through Berrly you will be able to create public events and each registered person will get an entry with a verification code. With this App you can verify that it is authentic and by letting the person save it.

With this traceability we can get an analysis to see how many people have shared event in a specific range of hours.
