PIN as the case may be via the video keypad 86 within the PIN area 84 via the
touch-screen 60, id. at ll. 19-21, of White's display.
19. In White, opaque "barriers 87 and 88 . . . form a physical privacy shield about
the video keypad 86 that blocks a third party from seeing the video keypad 86 and thus
a user's PIN during PIN entry." Col. 11, ll. 39-42.
20. White does not expressly mention that its barriers can be changed between
opaque and transparent states.
21. In its advertising mode, when White's workstation is showing a promotional
program rather than interacting with a user, displaying a video keypad is unnecessary
and would reduce from the space available for the promotional program, which would
make the program less noticeable to passersby.
22. In its advertising mode, when White's workstation is showing the promotional
program rather than interacting with a user, opaque barriers would undesirably obscure
a passerby's view of the program.
23. Byker is prior art under § 102(e).
