While many industries are beginning to add 2D codes, such as Data Matrix or QR, to provide additional tracking information to parts, not all industries are adopting these types of codes quickly. It's important to know that some image-based readers help make the transition easier, with a lower cost model. Image-based ID readers stand poised to replace laser scanners in a wide range of industries. Thanks to advances in microprocessors, imaging sensors and decoding algorithms, this solution has become more affordable and more powerful.
