I recently received an email from UCSD, my healthcare provider, with an invitation to get my 2nd Moderna COVID-19 shot. The email included a QR code image that I had to bring with me. At the mass inoculation site they scanned the image on my iPhone to verify my appointment. Neat! I became curious about QR codes, and found this article:

“QR codes are now so ubiquitous that hardly a day goes by without seeing one. What is more, novel uses are constantly being though up. Recently, the codes have even begun to appear on gravestones as part of a service that provides information on the deceased. [ ]

Denso engineer Hara Masahiro invented the QR code 25 years ago. The division where he worked was subsequently split off into a subsidiary named Denso Wave, where he now holds the post of chief engineer…”

The standard UPC bar code is easier to interpret:

"Fat bar, skinny bar, fat bar, fat bar,

Fat bar, skinny bar, dollar twenty-nine."

-- Harry, on Third Rock From The Sun

I knew that they originated out of the auto/parts industry. Didn't know the inventor is still part of the company, pretty cool.

QR codes are pretty cool. Nowadays they're used for all kinds of stuff.

We use a bunch of bar codes at work. More and more, I'm having us use 2D bar codes instead of "fat-bar-skinny-bar."

We don't use QR, but we're using the heck out of some Data Matrix (very similar in appearance) these days.

Thank you for the article link, Pipe Smoker.

Mark of the beast...

Now that most smart phones can read and open QR codes directly from the camera App, they have become pretty handy for a lot uses.

Gas pumps at Sam's Club have QR codes to scan and pay for fuel.

My 2 invitations to get Covid shots and Mrs. Flash's 2 invitations all had QR codes on them and the helpers carried iPads they read the codes with.

You gotta love technology, and I know I do. I've even gotten used to talking to my car to get it to do things.

My S&W .380 Shield EZ has a QR code printed next to the SN. Haven’t found an iPhone app yet that’ll read it since it’s so small I can’t get a good picture or maybe it’s some non-standard format.

Checkout registers at Publix grocery stores, and Walmart registers, too.

If you're uncomfortable with the use of bar codes and QR codes, don't go near the hospital. Most hospitals are now using bar and QR coding on both patient records as well as all testing performed. Almost nothing carries an actual representation of the patient's name anymore. We've all been reduced to numbers, lines, dashes, and squiggles at this point and it will only expand over time. Personally, I've always been amazed at the simplicity of this tech when compared to so many other aspects of our lives.

I’m in advertising and they go on tons of stuff. Most food packaging will link you to their website to find the same and similar foods. Local restaurants are using them so when you get inside there is a QR code at the center of the table. It takes you to a link of their current menu so no physical menus are needed.

As far as UPC’s are concerned there is a new technology that puts an invisible code over the entire package so that the checkout person can scan the package anywhere.

I'm just glad the readers have vastly improved!

Along with bar codes they were "marks of the devil"
And ppl were saying it's the beginning of the end ...
Now that we are where we are as a country I can't say it was not that. But at the time allot of fear mongering was going on.
But like blue ray it spun up only to become non main stream like it was hyped up to be.

Well, I can't use them. I don't have a "smart phone" and don't carry a tablet. My flip phone is only used for calls out--I don't know if it is even able to work QR codes.

Any restaurant I go to had better have a printed menu or at least a screen at the table where I can make selections. I may be a Troglodyte, but it's my money and if they want any of it they had better provide a way for me to order stuff without a smart phone.

Got a QR writer many years ago.

Would print out 3 codes.

The one on the left and right would display 'Not this one... the other one!'.

The one in the center would display 'Don't scan this code, you don't know where it has been...'.
