So I bought my tickets on Stubhub . Where my mobile tickets are the ticket says do not screenshot tickets because the bar code changes frequently. Do I need to print out tickets from printer or will they scan my phone at the stadium? Only

Or download Google pay app and type in stubhub in search bar..and your tickets are there!

Do not screenshot or print out your tickets. Neither one of those methods will work with the new scanning system. Your phone will be fine. Just make sure you store it in mobile wallet, where you have access to it when you enter the stadium. If you have any issues the guest services staff will help you out. If you have any other issues, the box office will help. Please try to enter at MetLife Gate, that way the box office is right there and you will not have to walk far for help.

You cannot print out the ticket, because the bar code will not register. You can store the tic in mobile wallet, where they can scan the QR CODE, or just display the moving bar code

I would print them for your peace of mind but I have bought tickets to the reds game and they scanned just fine
