I had to take a dive through this website to figure out why the hell someone would charge people to generate a QR Code. It doesn't cost anything to make a QR Code; just like a barcode, it's just a way to scan text. If anyone else was wondering this like I was, here's what I've figured out. Firstly, yes - they require you to sign up (and enter the trial period for Pro) to generate codes, even plain-text, web link, SMS, and email address codes. As far as the codes themselves go, they allow you to change the colors, embed a logo, and export the code in different image formats. This is where anything having to do with the QR Codes themselves stops. It seems every code they generate actually links to their website, where they track visit metrics, give the option to host a webpage for you, and have a lot of different options for different types of landing pages. In this regard, yes, it makes sense for them to charge. However, charging for plain "vanilla" QR Codes seems a bit misleadingly greedy. I can't find any option to just make a plain black-and-white code on their site without joining the trial. I haven't joined the trial either, but I have a feeling even the plain-text or such codes still probably link to a page on their site for the sake of tracking metrics and locking the code when your membership expires. Again, I don't know that for sure, but that's what it seems like. QR Codes don't have expiration dates, especially codes like plain-text and the like. I can't say for sure that they do, but if they make such codes expire, that's about as asshole as it gets - creating a problem where none existed in the first place. That's what it looks like to me.
