The guiding frame is an accessory used on a touch screen payment terminal; the overall form is a polygon frame, with a cutting edge style at lower corners; indicator protrusions are arranged on the surface of borders to correspond to the password buttons displayed on the touch screen, so as to assist visually-impaired people in inputting PIN code on the touch screen.

The broken lines represent an environment of use in a Point of Sale machine and form no part of the claim.
