Went to a Coyote's game tonight and before entry - at the gate - I had to scan the QR code on the back of a clipboard to download an app from Clear, answer their Covid questions, then take a photo of my DL (front and back (which didn't "match" the first few times)). I was then given a QR code to enter with my ticket.
First game I went to a couple of weeks ago didn't require any of this. Here is a pic of peeps around me doing the same.
Not sure if I am now in a database for future events. I must be but didn't make an account or anything to track. It was very uncomfortable. Coyotes lost but got us all a free Taco Bell taco in the process buy scoring in the 3rd. No purchase or ticket stub required. I will not be eating that bull crap.
