In the sixties of the last century, when Japan began a period of economic growth in almost all fields, sales began to expand, especially in various fields of industry, and exports began to all countries of the world. These goods required reviews, examination and recording of all their data in records throughout the day and night, and this matter required a tremendous and hard effort to record and write this data.
At that time, only the manual method was available, so the cashiers had to record everything with their hands, and this is undoubtedly a grueling suffering for these people, and most of them suffered from some types of anesthesia or pain and possibly paralysis in their fingertips, and many of them had "carpal tunnel syndrome", which is a symptom of severe pain in the hand. Or numbness and tingling, or even things falling from their hands a lot, and other damage to them. These money-changers yearned for a way to relieve them of this burden. The invention of the QR Code provided a definitive solution to these problems.
The first to invent the QR Code code was the Japanese company “DENSO WAVE” specialized in manufacturing auto parts. It was established in 1949 and it is a group of Toyota Corporation. Letters or symbols, including types such as numerical, which contains a maximum of 7089 characters, or alphanumeric and contains a maximum of 4296 characters, or kanji and contains a maximum of 1817 characters.
The use of QR Code is now widespread in all fields, and applications for it have been created on various devices, and this has contributed to its spread a lot.
Among the most important uses of it: If you want to know the data of anything, you can only photograph the QR Code box, through this code you can enter the websites, as well as open an application link in the application store, or call a phone number or add it to the phone book, or connect to the Wi-Fi network -Vi, you can send an SMS message, or send an email immediately.
In iOS 11, Apple introduced the feature of scanning the QR Code via the camera application in an easy and fast way, and this undoubtedly will increase the popularity of using QR Code.
How to scan a QR code
◉ Open the camera app.
◉ Point the phone at the QR code box.
◉ A notification will appear at the top of the screen with all the data stored in this code, then click on this notification and get all the data.
How to disable QR code reading
◉ Open Settings from iPhone or iPad.
◉ Enter the camera settings, then close "Scanning QR Codes".
Not only the camera app supports QR Code but also the Safari browser
If you are browsing a website and you find a QR Code on it, you can also scan the QR Code from the image by touching it long ...
Example:
◉ Press This link To open a QR Code image in Safari
◉ If you are in a sync app, the image must be opened in Safari, so click the Safari icon
◉ Then touch the picture and keep your finger on it and not press 3D Touch, but touch
◉ You will see an option to open the site that the QR Code symbolizes at the beginning of the list
◉ So, when you are browsing a site on Safari, and you find an image of the QR Code, all you have to do is touch the image for a long time to show you in the first option what this code will lead to.

I've tried it on the 6s and it's perfect but I have a question
A friend sent me a picture with a QR code on it, so how can I use the code while it is in the image I have saved?
There are no advantages, nor are they grieving, by God that it is ruined, and they are not all wrong and suspended.
By God, your words are correct, because I am the same thing as the iPhone 6 mobile, it gets stuck and slow, and the screen suddenly turns black and after a while it returns
Outside of the text, I notice a slowdown in loading comments, as I waited more than 10 seconds for it to load
The article is good and contains two information. The first I knew before and tried it, but the barcode reading information from Safari Hi I knew it from the article, so thank you
For everyone who complains about the recent bad system .. I would like to remind you of the ios 10 system the first time it was made available to the users .. your complaint was just like your complaint now of the iOS 11 system .. but after several updates the system stabilized and loved it to the point that you hated the current system .. so your patience is on You love the apple, and God willing, the system will improve and become more stable ... as long as you like.
Excellent 👍🏼
I also have another question 😅
What is the difference between the QR code and the bar code ???
Thank you for the useful and beautiful article as usual 😊
But I have a question, how can you create a QR Code or put information inside the QR Code, as you did in the example in the article to open the app.
Can someone give me the name of this phone https://i.ytimg.com/vi/O5jDvHe52ag/maxresdefault.jpg Is it possible to see me in Jarir? Salvation without the iPhone is enough, raise my status: (
The worst system in the history of Apple ios 11
The battery is running out terribly
A beautiful and wonderful feature, and frankly, all the advantages of the new system are wonderful, but it is the worst system in terms of performance ,, the previous systems were beautiful and had advantages as well, but this time the performance is very bad ,, I have iPhone 6s and slow and sometimes it heats and applications are slow and collapse sometimes Tired of this version ...
