I’ve always seen plenty of bottle neck entrances or certain 1 way gates to keep people from sneaking out of the entrance.
But almost every big box store in my area has these electronic scanners that have to read you before opening a really weak little partition to ALLOW you in.

They’re purely meant to read you approaching and decide to let you in or lights and sirens go off.
So they seem pretty well postured to just change the criteria for what the scanners require.
