Why Choose LEADTOOLS Barcode?

  • LEADTOOLS is the most comprehensive barcode toolkit on the market, supporting both reading and writing of over 100 barcode types and sub-types in both bitonal and color images, including all major 1D and 2D barcodes.
  • Reduce the bottleneck issues in high-speed scanning applications by utilizing the fastest barcode recognition speed. In addition, you can maximize the benefits of today's high-speed processors by taking advantage of multiple threads and cores.
  • Integrating barcode functionality into your application is very easy; reading and writing barcodes can be accomplished with only a few lines of code.
  • LEADTOOLS is designed to allow our developers to add new barcode types and barcode "flavors" rapidly. If you find a barcode that we cannot recognize, we will be able to update our engine quickly to add the barcode type.
  • Achieve very high accuracy even on poor quality images with damaged barcodes. The better the accuracy, the less human interaction that is required, resulting in substantial savings of time and money.
  • When used in conjunction with LEADTOOLS Document Imaging SDKs, you can clean noisy or damaged images to improve recognition accuracy with powerful document image processing and enhancement technology.
  • LEADTOOLS offers a diverse offering of imaging technologies alongside its Barcode SDK Technology. These SDKs include many additional imaging features such as extensive image file format support for reading and writing several raster, vector, and document file types, numerous image processing routines, document image cleanup, annotation, compression, scanning, medical imaging components, multimedia components, and mobile device support.
