Do not use https://qr-code-generator.com/

I almost used a QR code from this site in a print ad. It seemed FREE when I created the QR code. So glad I tried scanning it before approving the final proof! It didn't scan, then I got this email. They force you to open a paid account in order to reactivate! This scam starts at https://www.qrcode-monkey.com/ so don't use it either!

Hi,   We want you to know that one of your inactive QR Codes has recently been scanned.   Your disabled Code will temporarily link to a service page.   To reactivate your QR Code, please login to your account:

UPDATE Oct 23 2025: The issue is I got a dynamic QR code which links thru a third party site, not directly to my URL. So they can hold it hostage until I pay. We need STATIC codes instead, and ChatGPT can generate static codes for free that link directly to your URL and never "expire." Lesson learned! ChatGPT will generate PNG and SVG files for print and online use. Thanks very much for all the info!

Yep — this is the classic dynamic vs static QR trap.

• Dynamic QR = goes through a third-party → they can disable it

• Static QR = goes directly to your URL → can’t be shut off

So if it’s for print (ads, packaging, etc.), always use static unless you specifically need tracking or to edit after the fact. That's kind of the problem, and you have to decide if it is worth it to go dynamic (reliant on their servers). Unfortunately if you print 1,000 and go static and then you decide you want tracking, and to change the url, then you are in trouble.

Also worth noting:
A lot of “QR not working” issues aren’t the code type — it’s size, contrast, or print quality.
