| Long Description | Covering over half of South America, Brazil has a diverse landscape including a vast expanse of rainforest, deserts and mountainous forests as well as being home to part of the River Amazon basin. The country's mixture of Amerindian and Portuguese influences has helped to create a rich cultural heritage. Brazil has the ninth largest economy in the world, but the gap between rich and poor in wider than almost anywhere in the world. As Brazil prepares itself for future economic expansion, closing the gap between rich and poor is a major challenge for the future. |

A Data Matrix code is a two-dimensional barcode make up of blocks of black and white modules put together to make either a square or rectangular pattern. The information to be encoded can be text or raw data.
Normally, data size is from a few bytes up to 1,556 bytes. The length of the data depends on the symbol dimension used. To make sure the data can be read even when the pattern is slightly damaged, error correction codes are added which increase symbol strength. A Data Matrix symbol can store up to 2,335 alphanumeric characters. Here is a sample you can scan.
Data Matrix symbols are rectangular in shape and usually square. As more data is added, modules are put together to allow for the data and error correction. Each module can be identified by the "L" shaped black line that runs down the left and across the bottom of each module. In the sample shown above, there are four modules. These "L" shaped sections are known as the "finder pattern". The top and right border of each module are made up of alternating light and dark blocks. Light blocks represent 0 (zero) and the dark blocks represent 1 (one). These are known as the "timing pattern". All of the blocks in the middle of each module make up the data and check codes. The entire pattern can range in size from 8x8 to 144x144 in size.
