Quote: "Just a tip based on my limited experience. When Encoding QR codes use a low number. The option is 0-3. I used 3 and released it to the public and found a lot of scans were failing (almost every time). It took me days to work out the problem. I set it as 0 and re-launched it and the scanning works 100% of the time now. 0 will probably also be easier for you to color with Memblocks too as I think it creates a less detailed QR code so less black pixels to color."
Thanks Kevin!
I am using 3 thinking the highest would be best, but I will switch that before release to avoid any problems.

I quickly googled online services and some of them not only put a logo in the middle but some put an image in the background with a low alpha setting. Might be something else to look at in your version to see what can be done."
I came across one of those last night too.
The ones I saw used a contrast, making dark dots for areas where the background image is light, and light dots where the background image is dark.
They looked nice for basic background images like the Facebook logo, but more complex background images caused a lot confusion in the final image.
I think they may be easier to create than removing parts of the code, but I have not tested them to see how easily they can be read.

I have this working now for PC only.
I can now generate an image that has a hidden message in it using my own encryption.
The message also contains a key-code necessary to unlock it.
Each device has 5 unique keys, so users can have different levels of users/groups as recipients.
Select your key (that your intended recipient uses, given by you), type your message, and click a button...
An image is generated with the message/key encrypted/embedded in the image, ready to send.
The message is invisible to the naked eye, and the image looks like a picture, not a message.
I currently limit the message to 4,000 characters, and the PNG image created is less than a 200x200 pixel square.
Here is an example...
And yes, this is a real example that has a hidden message.
