Depending whether you created a static or a dynamic QR Code, we can help you.
Go to http://qrcode.kaywa.com and log in. If the QR Code that you need to change is displayed below the generator on your dashboard, you can just click on “edit” next to your URL and upgrade to a paid plan that includes this service. Your dashboard should look like this:
If your code is not listed as shown in the picture, you generated a free static QR Code. Static codes are different from a technical point of view. This means that the content that you chose is literally “in” the black dots of your code. Unfortunately, we cannot change static codes for you, nor can we add them to a paid account.
So what are your options? The only thing you can do is ask your webmaster to redirect the URL in the code to the correct address.
To prevent these issues, we highly recommend that you subscribe to one of our plans. Prices start at just $15/month. See all of our plans at http://qrcode.kaywa.com/static/pricing#qr_mgmt_plans. With dynamic codes, not only are your QR Codes safe, but you can also learn how many people have scanned your code, where they were when they scanned it, and with what type of device. This information provides clues about the effectiveness of your QR Code usage.
