Abstract:
Bar Codes have proved themselves as the most efficient, cheapest and the only reliable choice
when it comes to AIDC (automatic identification and data collection). For the last few decades
Barcode industry has come a long way from just identifying an object to now when we can
encode more then three thousand characters into 1-2 square inches image. Reliability is
guaranteed. Efficiency is main reason bar codes are brought into play as speed of business is
multiplied. Corporation which could not make more then a hundred thousand transactions a day
are now talking about millions of them a day. How? Thanks to bar codes.
The Barcodes which could only identify items are !-Dimensional barcodes and those which can
encode large amount of data are 2-Dimensional barcodes. 2-Dimensional barcodes now enjoy a
large user base because of their enormous benefits as described in INTRODUCTION. The
purpose of this software being developed is to take all the benefits 2-Dimansional Bar Code can
provide.
The objective of this project is to make a commercial product named as DATAMATRIX
Barcode Control in the form of an Active-X control which will generate the most reliable
barcode cal led DATA MATRIX. This Barcode can encode up to 3000 characters and has many
schemes to compress different types of data. Active-X implementation will enable any c lient to
use this software.
If we describe the project in shortest words, Data from user is given as input to the software
which is then compressed and algorithms are applied to ensure the recovery from error, which
enables to recover to some predetermined user selectable percentage. The data is then represented
as an image in some predetermined pattern by fo llowing the international standards so that any
2-D Bar Code reader can retrieve the data out of image. This way this software provides a perfect
solution of the problem faced by large scale manufacturing industry, i.e. AIDC (automatic
identification and data collection).
