How to do the QR code instruction? The kind that you can read directly by scanning the code?

The QR code instruction can be generated by a QR code generator. Take the computer upstream of the code as an example, the steps are as follows:

1. Open a browser on your computer, search for the code upstream, enter the QR code URL upstream, or enter the URL ma3you.com. The code upstream supports all browsers except IE, such as Firefox, Google, QQ, 360 and so on.

2. Then enter the management page, and select the QR code content in the left menu to enter the QR code management page. (If you are logging in for the first time, you need to bind your mobile phone number before doing the following. )

3. Click the Add QR code content button.

4. Edit the content to be displayed on the QR code editing page.

5. After editing, click Save.

6. After saving, the page will automatically jump to the QR code display page, which you can identify by scanning.

It should be noted that after the content is generated, it can be modified by using the QR code upstream of the code, but the QR code will never change. In other words, after the QR code is printed or made into a display card, the content can be modified without re-making or printing the QR code. Go to the code upstream website to learn more.
