Why is my QR code not working?

The readability of a QR code is primarily determined by the size, the input length, the error correction level and any possible logo over the image. It is also possible that the scanner may not detect it because there is not enough contrast between the foreground and the background colors. You must remember that it is essential that the foreground is always darker than the background. In case of any difficulty, do not hesitate to contact us.
