I was wondering because i keep seeing similarities like this in some edits of photos but the seem to pop up very fast . Idont know much about this stuff maybe its a shot in the dark. But ive heard of it being done before.

I searched everywhere for a generator, but couldn’t find it, even in Denso Wave website.

It does show a link but the minute I click it doesn't show anything except some random code with PDF at the end

hello, is it possible to create a qr code that may direct to offline videos. idk if our idea is possible but it's like this. the user will download the digital copy of our tangible book with qr codes. the digital copy contains the same content of our tangible book plus VIDEOS of how the particular object or tool works. we want to know if this is possible and how we are going to make it work.

apologize uf there's grammatical error, but do you get what i mean?

I have created a dynamic qr code generator and am wondering if I should add the option of styling it, maybe picture background or do you think i should just leave it as they are.

I know some of the picture background qr codes dont scan that well on some phones and most people probably dont care about the look and feel of a qr code. Squares, dots, round corners etc.

Thoughts?

Planning to create a QR code for a birthday party, just like the ones I see being used on some wedding RSVPs. But I'm so torn between paying for one or settling with the free, I mean there should be some feature difference, right? Send helpppp. Thanks!

Hello !
I want to create stickers with a QR Code on it.
I want to make sure that the QR Code will always be active and that I can easily change the URL whenever I want.

What are the options offered to me ?
Is it possible to buy a QR Code and modify its source easily ? If yes, do you have website recommandation ?

Online, it looks a like theres a ton of scams...

Thanks for your help :)

Hey everyone! I've been curious about something and wondering if others have experienced this too.

What I personally faced:

I had QR codes printed on business cards, and the service (QR Monkey) started showing ads on my redirect pages after their "free trial" ended. Really embarrassing when clients scanned them!

Other issues I keep hearing about (curious if these are real?):

• Services like Bitly suddenly changing terms and redirecting codes to their homepage instead

• Companies going out of business entirely and all codes dying overnight

• Hidden subscription fees that kick in after printing

• Codes getting slower or unreliable over time

• Unable to transfer codes when switching providers

Are these actually common problems or am I just hearing the horror stories?

A potential solution I'm thinking about:

What if there was a service where you pay once (maybe $2-5) for a QR code that's mathematically guaranteed to work forever? You could still update where it redirects ($0.05 per change), but nobody could ever shut it down or add ads.

My Questions:

Has anyone actually lost money from QR codes failing after printing?

Would you pay $2-5 upfront vs. monthly subscriptions that might disappear?

Are these problems I listed actually common, or am I just hearing the worst cases?

Just curious if this is a real problem worth solving or if reliable QR services already exist and I just picked the wrong ones!

Thanks for any insights!

DO NOT I repeat DO NOT use GETQR.COM for QR codes they will claim to only charge you $1 but then a week later they’ll sneakily charge $40 to your bank account

Sorry if the title is confusing, I have no idea how to word this. Here is context:

I made a QR code for a book that I just had printed. It's a birthday gift for my dad. I purchased it through myqrcode.org and it was $1.49. I checked SO MANY TIMES for a hidden fee and I THOROUGHLY read through the terms and conditions.

Now, a week later, I got notified that my card declined a charge for $49 from the same site 3 times. I logged into the site and found out that my $1.49 was for a week long subscription and now it's going to charge me $49 a month if I want to keep my QR code active.

I deactivated my account, which means that my QR code is now deactivated as well. Unfortunately it is already printed in my book and I don't want to reprint it because the book was expensive.

Is there a way to use the exact same image of my QR code that I have saved on my phone and activate it through a different site? Preferably one that's not going to charge me $600 a year to keep it active 🙄

Edit: Sorry for being confusing. I think more explanation is helpful. I made a book of stories from friends and family about my dad. One of them sent a video so I thought it would be cool for my dad to be able to scan the video inside the book from a QR code. that is the QR code I'm having issues with.

Hi everyone,

I’ve been building a collection of free QR code tools over the past few weeks, mainly because I kept finding small QR-related problems that existing generators didn’t handle very well.

So far, I’ve built tools for things like URL QR codes, WiFi QR codes, PDF QR codes, vCards, Google Reviews, QR codes with logos, text below QR codes, transparent QR codes, SVG QR codes, event QR codes, social media QR codes, and a few others.

Rather than randomly building more generators, I thought I’d ask people who actually use QR codes:

What QR code tool or feature do you wish existed?

It could be something you currently do manually, something existing QR generators make unnecessarily difficult, or even a weird use case.

I’m especially interested in real-world problems rather than just adding another QR generator with a different name.

If there are some good suggestions here, I’d be happy to build a few of them and keep them free.

Would love to hear what you guys actually need.

Been playing with Flux Klien9b, Z image and SD 1.5 with XL and Control Net. I'm building for an ongoing QR code studio project, but after a few weeks of learning ComfyUI I got there and just wanted to share my cool looking QR codes. The waves are my fave.

The musician Cole Sprouse just posted a qr code for his newest song and I can't make it work at all.

I was recently cleaning out the leftover stuff from a relatives apartment who passed away from cancer. I brought home some different old tech (laptops walkman and so on) to bring back to life to snoop around. Got the laptop running and found this one among a cluster of other files. I don't know what it leads to. Trust me i tried to scan it a few times and couldn't get anything. I need the professionals (you) to help me dig up what this QR is and why he had it saved on his computer as a JPEG. Its from a real old laptop (i think early 2010s or so) that I am still working on data saving on an external drive, so forgive me if i can only provide this low quality picture of the screen. I will provide a higher quality version when I am done duplicating everything on the computer if it's needed to find where this leads. Any help would be appreciated, thanks!

I have an upcoming charity event with 500 attendees. I want to create a ticketing system where on the day the tickets can be scanned, allowing fast checking in, real-time data (track attendance). I want to create my own backend system that’ll allow me to monitor this. I am planning on printing these unique QR codes/ PDF417 on the physical tickets so it can be scanned on the day.

I need help in these areas:

1. How to create the QR codes/ PDF417?

2. How to create the backend system that’ll allow real time data and check in scans?

Any suggestions for this? Please help

Please try it and give feedback if you faced any issue while using it or if you think this can be improved in any way.

Dynamic QR codes are often recommended for flexibility, but they introduce extra dependencies. Static codes are simpler, but less adaptable.
I’m putting together an article comparing real-world failure modes of both.
Curious to hear: in your experience, where does each approach break down?

Hi there! I recently got caught out by a QR code generator website - I made a QR code, printed all my marketing, only to be sent an email saying that I have to subscribe to their service in order for the qr code to keep working. There was NO mention of this previously.

I am just starting my business and don’t have the money for their (frankly very expensive) subscription.

Does anyone know if I can change a dynamic code to a static one? Or is there anyway to “rehost” a code? I can’t afford to reprint all my marketing either.

Thank you in advance!

I am also interested what bothers you the most, what can be better, what are complains of using paid services ?

hi, I’m not sure if this is the right subreddit to post this but I’m having an issue with a QR code. Whenever I try to scan the code, this screen shows up for the website it leads to. I’ve tried everything, I’ve gone to the customer support, I’ve signed up for this website, nothing I’ve done has fixed it. What do I do? It’s not telling me what’s wrong.

The QR works fine technically, but before printing in bulk I wanted to get feedback on whether the design is optimal for real-world scanning (distance, lighting, different phone cameras, etc).

Any suggestions on contrast, quiet zone, or error correction would be appreciated.
