The lasers used in barcode scanners are almost certainly under 1mW in
beam power, which makes them class II.
I took a look last time I was in my local supermarket. They have the
scanners with the * shaped windows, which I think is what the original
question was about.
The scanner in question was clearly marked "class IIA." There was also
a caution about not looking directly at the beam for too long.
The cashier looked at me a little funny as I was checking this out.
