What is a QR code?

Before getting started with and any system that uses QR code scanning and tracking, it is a good idea to understand how QR codes work to get the most benefit from QR codes.

QR codes are a more modern version of barcodes, mainly adopted as a marketing tool. QR codes were originally designed to track complex part numbers which had much longer codes and could store more data them than a 1D barcode. In addition the QR codes have a more robust decoding algorithm which means they can be decoded by most modern phone cameras. This has created a new engagement tool for consumers using their phones to scan a QR code and be directed to a online marketing campaign.

How do a QR code work?

QR codes are a graphic representation of data in a pattern of square blocks.

In simple terms, the number 1234 can be displayed as:

Barcode 1234

An optical imager or modern phone camera can be used to read and decode the QR code. This means we can use a barcode scanner to quickly and accurately read the barcode.
