There are many reasons why a QR code is not working correctly. My QR code is not working, what can I do? Please try another QR code scanner app for better results. Not all QR code scanners follow the official vCard standard which results in mixed up contact fields. Why is my vCard QR code not showing the correct fields? We cache your qr code image files for 24h on our server to optimize the performance of QRCode Monkey. We do not save or reuse your data in any form. There is no limit and the created QR code will work forever. You just can’t edit the content of the QR Codes again.
They do not expire and will work forever! QR Codes created with QRCode Monkey are static and do not stop working after a certain time.

QR code stands for Quick Response Code and is barcode type that was invented by Denso Wave in 1994. Attractive QR codes can increase the amount of scans. Add a gradient color to the QR code body and make it really stand out. You can also set your own colors for all QR code elements. You can customize the shape and form of the corner elements and the body of the QR code. Make your QR code look really unique with our design and color options. We can put a logo image on the QR code that covers up to 30%. This means 30% of the QR code (excluding the corner elements) can be removed and the QR code is still working. Every QR code can have an error correction up to 30%. With QRCode Monkey it is very simple and straightforward to add a logo to your QR Code. The created QR codes are static so the only limitation is that you can't edit the QR code again. All generated QR codes will work forever, do not expire and have no scanning limits like you see at other commercial QR code generators. If enabled, it will show exactly which colors in the input PNG got matched.QRCode Monkey also has no limitations. Also, for your convenience, we've added the preview mask option. To get rid of these pixels, you can use the edge smoothing option, which mixes the colors of the old and new pixels, making a smooth transition between colors. Often, pixels of the original color pixels still remain on the border or at the edge of old and new colors. It looks at the lightness parameter (geek note: that's "L" in "HSL") of the original pixels and sets the same lightness for the pixels of the new color. To preserve tints, shadows, and gradients in the output PNG, you can activate the "Preserve Color Shades" option. If the similar color match option is set to a value that's greater than 0%, then not only the indicated color is replaced, but also its shades and tones. All pixels of the selected color are immediately replaced with the new color and you can see the effect in the output preview field. The color for the replacement can be specified in the options as a color name, color code, or rgb(r,g,b) function, or you can select it directly from the input image by clicking on a color pixel in the input PNG. For example, you can match 10% of possible green colors, which include sea green, jungle green, and forest green. For example, you can quickly swap red with blue, or yellow with white. This browser-based utility replaces any color in a PNG (Portable Network Graphics) picture with a new color.
