why not put sheilds around the key pad; even angle inwards to prevent snoops at ALL entry points.?

Question

ATMs, grocery stores, gas stations, retail stores and the like should put angled sheilds to prevent snoops. Why haven't they? They say use your hand to shield but that's not very effective. Advise users NEVER to give SS numbers in emails or phony websites asking strange questions. Also, change your PIN often. My kids know it from watching me from the passenger seat. My bank did reimburse my when I was phished in email. PLEASE DON'T BE STUPID LIKE ME!

Answer 1

One reason is that it would make it very inconvenient to use the keypads.
