Just realized my barber shop on 5th Street is running customer cards through a tablet on public wifi
I was sitting in the chair at Ray's on 5th Street last week and watched him swipe three cards on a little tablet. The wifi name on the screen was "BarberShop_Guest" with no password, same one customers use. If that tablet is on that network, anyone in the parking lot could be sitting on it too. Anyone else seen small shops do this, and is there a cheap way to tell them to fix it without sounding like a jerk?
