scanning the code thing on nfs rivals to get into ea

You need a QR code reader to scan the code. Alternatively, you can just go to http://network.needforspeed.com/n (since that is the URL which the QR code points to) and log in with your origin account at http://nfsnetwork.com (which will redirect you to https://network.needforspeed.com/) to access the overwatch features of NFS Rivals.
