Data Matrix Barcode Control

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).
