QR Code is a two-dimensional (matrix) barcode format initially developed, patented and owned by Toyota subsidiary Denso Wave for car parts management; it is now in the public domain. The “QR” is derived from “Quick Response”, as the creator intended the barcode to allow its contents to be decoded rapidly. It can store up to 2,335 ASCII characters in one barcode symbol, and includes Error Correction Code (ECC) which allows error-free reading even when a symbol has been partially lost or destroyed.
The QR Code consists of black modules arranged in a square pattern on a white background. The information encoded can be text, URL, or other data. Its components include: quiet zone, finder patterns, alignment pattern, timing pattern, version information, data cells and error correction.
QR Code is readable from any direction. The alignment patterns at the three corners of the image enables rapid reading, while the timing pattern allows for the code to be read even if distortion or damage has occurred.
Originally used in the automotive industry to track automobile parts, the QR Code has now become nearly commonplace in consumer marketing. Directing consumers to a brand Website with a single scan and offering product loyalty rewards and coupons in exchange for gathering analytics it's seductive to consumers looking for product knowledge. In addition to consumer marketing, it's utilized for product and time tracking, item identification, and document management.
The Cognex Mobile Barcode Scanner SDK supports QR Code detection, enabling developers to gather relevant workflow and application data. You can download the SDK for free by registering on the Cognex Mobile Barcode Developer Network. Packaged with the consumer product barcodes of EAN, UPC, and GS1 Databar, the SDK Consumer Developer License (CDL) lets you deliver a powerful retail experience quickly and easily. In addition, the Barcode Scanner SDK supports a broad range of symbologies to meet your growing development needs.
Developing practical applications is challenging. That’s why we've developed a straight-forward barcode scanner software development kit (SDK) that boasts the most powerful scanning experience available for integration. It offers developers a simple, flexible, dynamic decoding experience, while still allowing for maximum control and flexibility over the user experience (UX). The Cognex Mobile Barcode Scanner SDK was built BY developers FOR developers... with the goal of making all your applications practical.
As a tool developed with the automotive, retail, manufacturing, government, healthcare, commercial services, and transportation industries in mind, our scanning solutions are built around efficiency for the end-user, as well as simplicity for the application developer. We understand that the enterprise is continually looking for opportunities to increase efficiency. Therefore, we have developed the ultimate single-handed scanning solution aimed at maximizing every promise of a return on investment.
