A barcode is a machine-readable representation of data related to the object it is attached to. Barcode readers read these codes in order to track the object throughout its lifecycle. Popular barcode symbologies include UPC-A, Code 39, Code 128, Interleaved 2 of 5, Data Matrix, QR, MaxiCode, and Aztec.
There are a few main reasons companies use barcodes:
Common types of barcode readers include laser scanners and image-based readers. Laser scanners can produce 1,300 scans/second and read 1-D codes from relatively long distances with the use of special optics. Image-based barcode readers have higher read rates than laser scanners, read 2-D and omnidirectional codes, and capture images of codes for data analysis, process improvement, and barcode quality feedback.
Cognex industrial, image-based barcode readers decode 1D and 2D codes, from printed labels to the hardest to read direct part mark (DPM) codes in manufacturing and logistics applications. Industry-leading read rates, advanced technology, modular options, and easy setup help reduce costs, optimize performance, increase throughput, and control traceability.
