  I must apologize. I incorrectly stated that the "brilliant guy" was leaving pertinent information showing in the barcode. I was informed that it's only a library card number. I made a poor choice in an example. However, I did find another urlLink example . My point was not intended to focus on the specific examples, but rather the incredulous act of uploading a picture of an official ID. In the future, I promise to be more careful of my example choices.
