Small Experiment: Can you guys help me test the reliability of QR codes generated by Opera Mini?

asked Jan 31 by Mahala QR  
I'm sure Opera intended their new QR code generator (available in latest update) to be mainly used to share long and complicated urls with people right there next to you but I couldn't help but be frustrated by the (low demand i'm sure) ability to save a nice, crispy vector file of said codes. So I took a screenshot instead! If you have a moment, could you help me test the reliability of these codes by scanning my screenshot from the link below and posting the result? I'm not sure if the codes expire or anything but I think I'm not the only one who would find an alternative qr generator in my pocket handy. The link should lead to the Noblesse subreddit. Thanks!

okay uhm, for someone who writes big words, (this talk of vector files) you happen to post questions someone who talks like you shouldnt post.
A QR code uses four standardized encoding modes (numeric, alphanumeric, byte/binary, and kanji ) to efficiently store data;
and - The Opera QR Code Generator makes it easy to share URLs between desktop and mobile clients.

so lets break it down. qr codes do not have a measure of reliability. its just like writing numbers on paper. so effectively u'd be asking me how my reliable my pen is. a qr code generator will create a code with price, name, website or url or wateva u want it to. it wil neva fail. ever. and a qr code reader will read said info.period.

next, just because you dont use something does not mean it's not in demand. i have rite now a phone, a desktop and a laptop.
when i google something and a workmate wants to go read it, they just scan the qr code from my pc or lappy and go away.  we've been doing it since 2011. so again, its in demand at my place of work and i dont know where you get this whole latest version business.

qr codes dont expire. i subscribe to PC Mag, and they embed site links in qr codes in their mags. i can stil scan qr codes from 2010 and they take me to the websites saved in the qr codes.
i have no idea what you mean by alternative qr code generator handy. you want to generate qr codes to for what in your pocket? to share a link, image, or whateva from your phone, we have Nfc, bluetooth, wifi share, mms, whatsapp etc.

edit - i forgot to mention, my QR code app doesnt just read screenshots. i can scan a code from magazines, products or scan from my pc screen, or get a qr code straight from my phone's screen, or from a saved image in my photo gallery.

oh, and yeah, your qr code takes me to reddit.

Thanks for the thorough reply @techspy007. About your concerns…

‘okay uhm, for someone who writes big words, (this talk of vector files) you happen to post questions someone who talks like you shouldnt post.’
I work in a print environment and had design training over 13 years ago, so while I may sound informed in some areas that overlap other disciplines, it doesn’t necessarily follow that I'd have a deep understanding of those areas.  Interest in things outside one's core field of expertise isn't a sin right?

‘and - The Opera QR Code Generator makes it easy to share URLs between desktop and mobile clients.’
I’ll try to be more explicit in my headings next time. I was asking about Opera Mini

‘it wil neva fail. ever. and a qr code reader will read said info.period.’
By asking other people to validate the code (across apps, os’s, browsers, locations etc), I wanted to find out if Opera Mini's codes were platform specific (you cleared that up nicely) and by dating the post, how long the code would last as dynamic qr codes can be recycled. Opera does not specify whether Opera Mini generates static or dynamic codes (I actually looked into this as far as my understanding could take me before asking). I wouldn’t want Opera to reassign the QR link on my client’s calendar to a grumpy cat meme 3 days later (definitely not the worst that could happen!)

‘next, just because you dont use something does not mean it's not in demand’
‘they just scan the qr code from my pc or lappy and go away.  we've been doing it since 2011. so again, its in demand at my place of work and i dont know where you get this whole latest version business.’
Again, sorry for my question not being clear. I’m asking specifically about the newly announced QR code functionality in Opera Mini (was it implemented in test versions in 2011?). It does not have an apparent ability to save a generated code. I think your comment about NFC, Bluetooth etc illustrates just how fringe my use case truly is even to you.

‘qr codes dont expire. i subscribe to PC Mag, and they embed site links in qr codes in their mags. i can stil scan qr codes from 2010 and they take me to the websites saved in the qr codes.’
My understanding of the premise behind dynamic codes is the main reason I came to this platform. Will look into it further

‘i have no idea what you mean by alternative qr code generator handy. you want to generate qr codes to for what in your pocket? to share a link, image, or whateva from your phone, we have Nfc, bluetooth, wifi share, mms, whatsapp etc.’
I’d like to use them in future print work. It’s why in addition to knowing how long a link is live (if it’s dynamic), a save function and vector option would have been gold for me. Alternative as in a viable option I could use on the go or offline to create and save codes without additional costs, user accounts or space used, for later use in artwork.

Thanks for taking the time!
