Readers that like inverted QR codes
In response side effects of metformin hcl 500mg to a conversation with @QRazystuff … Here are a list of readers that like and dont like inverted QR codes. Vendors, step up your game ! This test was performed on iphone 3gs – I cannot speak for other models.

Now, I will comment that I have only ever seen 2 inverted QR codes in the wild. However, if the readers are supposed to just detect contrast, why not? I don’t see any reason why we cant start making more codes like this, except, the majority of readers by this test do not support them. Onward and upward.

Speaking of tweaked codes that will or won’t read was anyone able to get this to work? http://www.setjapan.com/qrcode/future-of-qr-codes-is-bright-thanks-to-set/?lang=en
I got it to work on neoreader and quickmark on iphone 3GS – Ive been having inigma problems lately. I worked on a custom code for an hour tweaking just to fit my top 3
:^! I also own an iphone 3GS (iOS 4) and lynkee 2 works perfectly on inverted codes; a very good reader with QR generator BTW.
