There seems to be some variance in systems. I //really// don't like the ones at my local WM. It disables the scanner until the bagging scale stabalizes, and you can't enter quantities. It basically speed-limits you to about 1 item every 2 seconds. The ones at the Target, don't lock out the scanner unless you scan something that is marked as having a security tag, and the degausser hasn't fired. Our local CVS has some, and they're fine, but anyone that can't use them (low vision, paying with cash (sometimess), or buying things that require ID) have to chase down the one or two roving employees in the store, which would be super annoying if you had to do it often. Personally, I tend to use SC when I have <5 items. Even on the "nice" systems, there's no way I can outpace someone who does this all day, has helpful tech (conveyor belts, a bagger (even if it's me), ability to enter quantity, can enter PLUs, doesn't have to deal with the system locking out the scanner whenever it feels like it).
