A Cognex barcode reader is an industrial-grade image-based scanner designed to read 1D and 2D barcodes quickly and reliably, even in challenging environments. Cognex is a global leader in machine vision and barcode reading technology, and their scanners are widely used in logistics, manufacturing, automotive, pharmaceutical, and retail industries.
Unlike laser scanners, Cognex readers use smart image sensors and software algorithms to decode barcodes and capture more data from damaged or low-contrast codes.
