I point my phone camera at my laptop screen, it automatically determimes it's seeing a QR and decodes it. NO lasers.

OMG I JUST GOT RICK ROLLED!!!!!!!!! 😆 😆 😆 😆 😆 😆 😆
Kaspersky isn't relevant because that's an antivirus company, it's not even in the same area of funtion
A QR code is still a bar code being shaped like an odd square doesn't change that.
A bar code 100% requires a laser to read because it's the basic utility of a bar code
BTW, I have never ever once seen a QR code open a web site on any phone

This was just using the stock Samsung camera app, which does auotmatically detect barcodes and shows the appropriate options.
Ok how did i just scan the qr code that @mikedt cleverly used without using a laser?
anyways go on and believe what you want to believe. i can't convince somebody who just does not want to learn anything. you have your mind set on qr codes needing lasers. i am now going to ignore this conversation going forward..........so please have a good night. i hope tomorrow will bring more sense to you.

Actually QR code was invented in Japan, by Nippon Denso. Originally for tracking and identifying automobile parts in factories and warehouses. But they freely license the IP for anyone to use.

Then the word scan needs to be completely eradicated from anything related to phones.
It's like the phrase "Long Press" I've never heard of that until phones and I still have no clue to wtf it means. All I know is that the word LONG is a segment of distance.
So whenever I hear anyone say the phrase "Long Press I make sure they see me put my phone about an arms length from me and then I start reaching towards it with my outstretched arm, I make sure they see me and I say what, you said long press so I'm doing long press I thought something special was going to happen.
I do this to show how dumb what they said is. If in the process I make a fool of myself, so be it, it's a small price to pay to show them why copying utter nonsense is a bad idea. What I did is not as bad as what they said.
The problem is that you have chosen to get hung up about the definition of one word. Actually "scan" as a matter of dictionary definition only means to look at something to get information, so actually image processing is closer to the normal meaning of the word than specialised devices used for reading barcodes (designed to respond only to specific simple patterns). Also the word predates the existence of lasers by centuries, and barcode scanners often use LEDs rather than lasers anyway - there's nothing about the process that requires the use of coherent radiation.
A QR code is a simple way of encoding a modest amount of information in a way that can identify the scale and orientation and hence allow simple decoding from an image. Linguistically calling the process of recording the image and extracting information from it "scanning" is as legitimate as using it for a barcode scanner, which records a pattern or reflected intensity and then uses software processing to identify edges, measure thickness of dark bands, and decode that into a string of digits. Both are actually primarily software processes, both are about extracting information from an image.
But honestly, what a fuss to make about a pedantic interpretation of one word? And bear in mind when I say that that I am an academic, so nit-picking about minor details is what my profession is commonly supposed to be all about!
I've honestly forgotten what your original point was trying to follow this sidetrack.And no, flashlight into a projector is not the same thing. A camera can capture information which can be extracted using software, so has all of the hardware needed. A flashlight has the ability to produce a single beam of light, effectively a single pixel (you can vary the intensity through software, but that's it). So it's different because the flashlight hardware lacks the capability project an image, whereas camera hardware is more than capable of recording the information needed for QR or barcode reading (yes, you can read ordinary barcodes this way as well).

that's not exactly true, either that or Kroger here has multiple arrays one for laser and another for QR, as if you use Kroger Pay, it generates a QR Code that you place over the same handheld Zebra thing which scans the barcodes and it goes 'beep' and there's your mobile payment. it's based on CurrentC, which is defunct but our area is out of date in some areas.
The late-50s Zenith 'Space command' TV was the first with such a remote control. it didn't need batteries (which makes modern ones obsolete in my view) and yes was the reason why car keys jingling or some child with decent enough vocal range could turn the set off or on. We had a Magnavox 'Star System' colour set that was made in the latet '70s and was one of the first with a on-screen display, that also used an 'emitter remote' that was similar, although it used a 9V battery. I could make quite the high pitched sounds and could hear such sounds; still can hear sounds in the upper range that I ain't supposed to hear, like dog whistles or flyback whine, so I could easily figure which sound made which action, so I scared a lot of folks with our 'haunted TV'
It contains more information - shop barcodes are limited to short numerical strings (which are usually printed with the code).
No, its "utility" is in encoding information that can be quickly read into a machine.
As I've said already, the scanner doesn't need to use a laser and many don't. And the technology is old, so the idea of illuminating the strip and measuring an intensity pattern was in part a consequence of the technology of the time: taking a photograph, identifying the code within it (ignoring other image features) and decoding it would have been a more demanding and expensive process back then.
I have. Many times, for many different purposes.

you're lucky Matt_C. around here all restaurants make you pull your phone out, scan a QR code and it either sends you a website in your browser with the menu, or downloads a pixelated PDF file of the menu. Even asking for a 'real' menu gets side stares from folks. I'm sorry if I want no smartphones in my life when out, and want some semblence of life before covid germaphobia.
Do you want a long wait, or do you want a long weight?
FYI the word LONG is also a segment of time, e.g. It's been long time. Look it up in a dictionary.
But anyway what has your diatribe got to do with Blu? The subject you started this thread with.

Good luck with your lawsuit against BLU...
Good luck with your lawsuit against BLU...
Where I am unless you scan a QR you're just not going to eat in many restaurants, certainly all the big names are like that now, McDonald's, KFC, Kung Fu Noodles, etc.
guys don't. no matter what you say, this guy will not listen. i tried but he does not care what you have to say. stop. don't waste your time or energy in this dumbass discussion.
