not going to happen.
have you ever seen 137 people walk by one tsa screener in 10 minutes? let alone a screener with that many people with various screen size cell phones.
I saw a continental gate at CLE having the toughest time with those scanners. they had to guess how to operate many users' cell phones in order to resize/zoom in on the barcode to scan. many times, after holding up the line for a few minues, they were unsuccessful and sent back to the ticketing agent for a reprint.
