Data Matrix codes are two-dimensional barcodes that can store a significant amount of information in a small space. They consist of black and white squares arranged in a grid pattern, allowing them to be scanned by devices like smartphones and barcode readers. These codes are often used in industries such as manufacturing, logistics, and healthcare for tracking products and managing inventory. One of the key advantages of Data Matrix codes is their ability to encode various types of data, including text, numbers, and even binary data. They are particularly useful for marking small items, as their compact size makes them ideal for labeling products like electronics, pharmaceuticals, and small parts.
