Abstract

The barcodes are used all over with high popularity in many applications. Data Matrix is one of the best barcode. It is a two dimensional barcode with high density.From the 254 byte ASCII character set it will encode to 3126 characters set. In this type a scanner used to identify the data barcode which is having a pattern called as “finder” pattern present all over around the all edges of the present symbol and the symbol can be built over square or rectangle grid. The barcode can be read easily using finder pattern without effect of the physical structure of that code. The two-dimensional data matrix code contains error correction technique even if there is physically code is damage. Data matrix barcodes make an efficient use of older types of convolution error correction method (ECC) .The Data matrix types ECC 000- ECC 140  is called as an older ECC version and can be considered as an expired and cannot  be used in any new applications. In this Method use Reed - Solomon code for error correction which is highly efficient.  Experimental results of data barcode matrix having more efficient and correct results as compared to existing techniques with great improved speed of performance.
