One way to do this is by adding "HTTP://" to the beginning of your generated code. Another is to look at the source code on the website you used to create the code. If it contains HTML, you'll want to make sure to delete any code that you don't need, like a header or footer.

Measures to increase your QR code security

The following are the measures to increase your QR code security :

1. Make sure your QR codes are not too big.

2. Make sure your QR codes contain less information.

3. Use a different QR code for every website and app.

4. Use a different QR code for every new website you open.

5. Don't use QR codes as links.

How long are QR Codes valid for?

The lifetime of the QR code is not very long. According to the QR Code Standard Agreement, a QR Code is suitable for ten years from the date of production. This means that if you printed a QR Code in 2009, it would still be active and usable ten years later.

What if the QR Code is not working?

Sometimes the QR code doesn't work. If this happens, don't worry. If you've done everything correctly, the code should lead you to an information page on the merchant's website or social media account. You may need to zoom into the image, which will make the code pop up more quickly.

How do I calculate the right size for my QR Code?

There's no specific formula for determining the correct size of your QR code. As long as you have a standard of measurement for the dimensions of the space you want to use, you should be able to find a size that works for you.

Remember that the code needs to be large enough to be readable on any smartphone, tablet, or digital device you plan to display it on. It also needs to be large enough to accommodate the text and image you're placing inside.
