Problem: The quiet zone that distinguishes the QR Code from the surroundings is too small or nonexistent, so the QR Code can’t be read. #1 Not enough space around the border Example of an unscannable QR Code without the quiet zone Here we’ve outlined the most common QR Code scanning problems and how they can be resolved. There are things to look out for such as color mismatches, materials the QR Code will be used on, its size, and more. While QR Codes are quite the sturdy technology and are easy to read with any smartphone, sometimes improper designs can render them unscannable. ![]() Typical QR Code scanning problems & their solutions Quiet zone: This space separates the data in the QR Code from surrounding graphic elements so that a scanner knows what to scan. QR Code format informationįormat information: These sections include error tolerance levels, as well as the data mask pattern (the pattern that creates the QR Code), so the QR Code is easy to scan. Out of seven total structural elements of a QR Code, there are three that focus on error correction: QR Code data and error correction keysĭata and error correction keys: These patterns hold the bulk of the data linked to the QR Code. This makes QR Codes extremely weather-resistant, which is what makes them ideal for product packaging that undergoes global shipping, as well as on print materials like billboards or posters that are hung outside. ![]() The pixelated parts you see on a QR Code are doubled so that if some are damaged, then others make up for them and still convey the data to the scanner. Known as error correction, QR Codes can sustain up to 30% of structural damage and still continue to function.

That’s why businesses around the globe have begun to use them to generate sales, as well as for internal business processes.

Consequently, they can hold much more information than Barcodes and are more accessible to the average person. This is why QR Codes were invented: they can be read both horizontally and vertically due to their square shape, as well as are easy to scan for any smartphone. As a result, Barcodes are quite limited in the information they can hold and were not enough for supermarkets that needed to increase their available products in order to meet customer demand. ![]() Barcodes are 2D, meaning they can only be read by a special scanner in a horizontal direction. QR Codes were originally developed as more advanced versions of Barcodes to help with product inventory management. ![]()
