How to read the QR code sent by email on the iPhone
Recently, the QR code is in the spotlight.This is because of the rapid spread of apps used for reading payments with smartphone cameras, but the reason is that they do not need special equipment.
The iPhone supported the QR code as the standard function of "camera" when iOS 11.Before that, I needed an application to read the QR code, but now I can read the contents just by holding the camera to the QR code.In iOS 12, the improvement is added, and when the camera application detects the QR code, the yellow mark is displayed in the four corners, making it easier to determine the aim.
The QR code is not only for payment.You can include a lot of information such as name, phone number, URL and email address.Since it is an image as a format, it is possible to attach it to the email and send it.If you set the data in the address book (contact information) to QR code, you can use it instead of a business card.
However, the QR code attached to the email cannot be read with the iPhone camera.The camera cannot shoot his (iPhone) display.If there is a smartphone that can read QR code, or if there is a device that can display a QR code such as a personal computer, if you are on the go, use the following procedure.Here we introduce how to use the Twitter app, but you can also use other apps that allow you to read the QR code that exists as an image file.
