This makes QR codes more reliable for applications where the code is exposed to potential damage, such as outdoor signage or product packaging that may be subject to wear and tear.
So, how does error correction work in QR codes? QR codes use Reed-Solomon error correction, a widely used algorithm in digital communication, to add redundancy and error detection capabilities. This algorithm allows for the correction of errors up to a certain level – the higher the error correction level, the more data can be recovered from a damaged code. The four levels of error correction provided by QR codes are:
Level L (Low):
Provides recovery of up to 7% of the data.
Level M (Medium):
Provides recovery of up to 15% of the data.
Level Q (Quartile):
Provides recovery of up to 25% of the data.
Level H (High):
Provides recovery of up to 30% of the data.
The error correction level can be chosen when generating a QR code, depending on the requirements of the application. It is important to note that higher error correction levels result in larger QR codes, as more data needs to be added to achieve redundancy.
In conclusion, QR codes are different from barcodes in many ways, one of which is their error correction capability. QR codes have built-in error correction, while barcodes do not. This makes QR codes more reliable and suitable for applications where the code may be subject to damage or wear and tear.
