A CM at BTMRR showed us the scanners where they normally take your FPs (by the water, before you make the turn to go through the turnstiles to go up the stairs). The CM at the beginning of the FP line will remind you to have your ticket or AP ready to scan, then you will use the machines at the regular spot.
Thanks for this info! That totally makes sense. Sounds like a good plan (if you have to scan something) I hope most people just scan their tickets or passes. I admit to getting irritated with people who reach for their phones to get scanned and then realize their phone went to sleep, they accidentally logged out, etc. I have season tickets for a sports team that went digital with their tickets last year and the lines to get in were way slower the entire season because of phone issues.
