Datamatrix

DataMatrix is a type of code used to store and share information. It looks like a bunch of squares with numbers and letters inside of them. They are like puzzles that computers can understand. When a computer reads a DataMatrix code, it can quickly understand what it says and use the information inside to do something specific. For example, if the DataMatrix code has your name and address inside, a computer can quickly know where to send a package.
