Both, stacked and data matrix are two types of two-dimensional barcodes. Data matrix which is one of the widely used two-dimensional barcodes is high density barcode and it consists of white and black modules or cells which are arranged in squares or rectangles. Such modules represent the raw data.

Up to the 2335 alphanumeric characters can be stored by the data matrix symbol and nearly 50 characters can be held by a small 2mm or 3 mm square. Using this barcode in commercial applications for identification and carrying of the data without the requirement of access to the central database, can be increased due to it's ability to hold so much information. Data matrix barcode's latest version can read the damaged codes in accurate manner and it is cost-efficient too. Identifying the product and tracking it throughout the manufacturing process can be done by data matrix barcode. Where the space is the biggest constraint, there data matrix barcodes can be used for very small items or products. Identity details like a unique number, the manufacturer ID and the part number will be stored by the data matrix code. Data matrix is selected for high security applications of the U.S. Ministry of the Defense for identification of its assets.
In order to read this data matrix barcodes and decode the information, a specialized scannere are required. Information which is presented in the data matrix code can not be decoded by the ordinary linear barcode scanner. Laser and CCD camera technologies are required for scanning. You can try Symbol barcode scanner which are available in laser and CCD camera technologies. You also need thermal transfer barcode printer in order to print those data matrix barcodes.
Thus the above information is about the data matrix barcode, which is more convenient and flexible to the businesses, which require the smallest and most dependable of barcode symbologies.
