Explaining the numbers in the image above:

  • The invoice’s information
  • The attendees which depending on the role you’re assigned, you can go into MEC and perform the check-in process


Checking-in can also be done via QR code scanning once the attendee shows you their QR code.
This can also be done using a QR Reader or third-party apps for Android and iOS.

Place the QR code in front of the camera, it will either check-in the user or give you a warning if there is an issue. Therefore, any chance of duplicates or fraud is eliminated since no one can simply create their own QR code and try to get in.
Once the attendee has checked-in, it’ll show the invoice as green and there will also be this icon:

In order to manually add a new invoice, click on Add New and then select your event. Afterwards, you’ll see the tickets for that event and you can use the form which has appeared to add a new invoice.

By clicking on Add Attendee, you’ll add a new user to your website but your invoice isn’t complete yet. You’ll need to publish the invoice in order to complete the process.
