Chapter 6: Using the NCR 4430 Emulation Application 6-15
UKPT PIN Entry Request (Function Code 15h, 70h)
The 4430 emulation application displays no message if multiple keys
are pressed (thus no action is required to restart numeric input).
If the PIN input is less than 4 characters, an error tone sounds, the PIN
entry is cleared and PIN input restarts with the next key pressed.
If the PIN input exceeds 12 characters, an error tone sounds indicating
the 13
th
character is not accepted. The original 12 PIN characters still
remain and can be accepted as entry by pressing the Enter key. The
Clear key is the only way to clear the PIN characters. By pressing the
Clear key one PIN character at a time can be cleared.
Pressing the Cancel key causes the PIN entry to be bypassed.
The numeric digit function key indicator, which is "0" (zero), is always
1 byte (and not 4 bits).
Begin Buffered Input (with Optional PIN) (Function Code 70h)
When the 4430 Emulation application receives the Function Code 70h
with an input field selecting optional PIN data as input, the following
applies.
If the PIN input is less than 4 characters, an error tone sounds, the PIN
entry is cleared and PIN input restarts with the next key pressed.
If the PIN input exceeds 12 characters, an error tone sounds indicating
the 13
th
character is not accepted. The original 12 PIN characters still
remain and can be accepted as entry by pressing the Enter key. The
Clear key is the only way to clear the PIN characters. By pressing the
Clear key one PIN character at a time can be cleared.
Pressing the Cancel key causes the PIN entry to be bypassed. The
Cancel key must be pressed again at this point if you want to “abort”
that input and return you back to the card swipe input.
