Abstract

A program is disclosed that controls the Input/Output of Point of Sale (POS) terminal according to the instruction streams described in a data file. The data file described in POS Script Language defines the response for the event triggered by POS application and manages the whole output formats and sequences (for example: display, print, drawer open and so on).

This text was extracted from an ASCII text file.
This is the abbreviated version, containing approximately 100% of the total text.

Data File Controlling User Interface for Point-of-Sale Terminal

      A program is disclosed that controls the Input/Output of Point
of Sale (POS) terminal according to the instruction streams described
in a data file.  The data file described in POS Script Language
defines the response for the event triggered by POS application and
manages the  whole output formats and sequences (for example:
display, print, drawer  open and so on).

      In Fig. 1, POS Script Language is a kind of C Language.  It
contains the control words, formula, and the functions to get any
data from the model objects in POS application.  In Fig. 2, The data
file defines the summary of the triggers from application and
responses to them by using POS Script Language.  The data file is
once converted to a binary file by POS Script Language Translator for
POS application to read and interpret efficiently.  In Fig. 3, when
POS application gets an event (1) from input device (for example:
keyboard, scanner, magnetic stripe reader and so on), reads the
converted data file and look up the adequate instruction streams for
the event (2).  Then the application performs exactly according to
the instructions read from the data file (3).

      When the user interface change request occurs, it needs no
customization of POS application.  ONLY the data file change makes it
possible to customize the display format, receipt/journal printer
output format and any other output devices.
