Tamarra and Deborah et al, Thank you for your posts and questions. Thanks to Erich I was able to create a QR code with zint although it doesn’t seem to allow me to add our County Library logo. It does give me pause re: how that QR code could be used nefariously? If I just invite a person to read my QR code with their cell phone QR reader could they misappropriate that QR code for unapproved activity? Fascinating conversation. I so appreciate all these helpful posts. Charles.

If anything gets embedded, it will be visible in the text. Like in Joe's example, you'd see a different domain that forwards to the URL you wanted. If you test it and the decoded string is exactly what you put into the generator, it's fine. (Whether the website you visited to generate that code is safe is a different question, so I second the recommendation of Zint or the tools built into your browser.) Most security risks of QR codes are really to the users. If the codes are posted in public places--like those little cards on restaurant tables to pay for your meal--someone could theoretically cover them up with a different code that tricks patrons into giving away their sensitive information, or downloads malware to their phones, etc. -Tamara
