QR code

The QR code (Quick Response) is a two-dimensional code for data capture. It consists of a square matrix of black and white boxes that represent data in binary form. The great advantage of the QR code over the barcode is its resistance to errors. Up to 30 per cent of the code can be lost (for example, due to damage or the like), while the code can still be read.

QR codes are widespread and can be found almost everywhere in everyday life. By now, almost every smartphone has a QR code to get information quickly. The industrial benefit of QR codes lies in the traceability of workpieces. Particularly with small series, it is helpful to scan the workpiece before and after each process step to ensure the most accurate cost consideration possible.

Prerequisites for use

Possibility of attaching QR codes to workpieces.

Not every workpiece can be provided with a QR code. Obstacles are, for example, the size of the workpiece or processes that would damage the code. Therefore, the use of QR codes must be considered according to the application.

Required infrastructure

Smartphones, scanners or decoding software are required to read QR codes.
