The only criticism I can think of, is the QR code is too "fat". It would have scanning difficulties in low-light conditions, especially QR readers with cheap cameras with low ISO tolerance. The Base45 encoded bytes should be cut at least by half to make fast scanning possible.
- kolinko 5y agoLow-light might not be an issue for people who will show the code on a mobile device. At least in Poland the code is available through the government id iphone/a droid app. Some people may print it, but most will probably just use the app.
- radicalbyte 5y agoWe've tested it extensively and, on modern hardware it's very easy to scan from a screen. The paper version is less good as paper bends..
- kiallmacinnes 5y agoIt's about as thin as it can be, given the requirements for offline validation, and the environment it's designed for (airports / other national borders etc). Nobody wants every verification resulting in a ping back to some central server doing who knows what.
- hanoz 5y agoNot long ago this kind of technology and anyone working on it would have been given a pretty rough ride on this forum, no matter how well designed. Now it's those raising concerns who are being hounded out with down-voting. How times have changed.
