The KPCP keypad
and KPCP PC software enables caravan park managers to allocate 4, 5 or 6 digit
PIN codes to the tenants of up to 1000 sites. Any site's PIN code can be given
an automatic expiry date and time or can be set to permanent for long term
residents. PIN codes can be typed in manually by the user or randomly selected
by the program. Regardless of how the PIN code is selected, automatic scanning
ensures that all codes in the database are unique and therefore not duplicated
in the system.
