How to send a QR code of a circle of friends in the same city?

Save the QR code in the mobile phone photo album and you can send it. Recommend a circle of friends to copy, and we take responsibility. Wechat forwarded the gift copy to the circle of friends, but I fell into the past memories. In short, people should still love each other when they scan the QR code. A complex mind is far more tiring than a simple one. Remember to add the QR code, and I will send you an account right now.

Meaning of QR code:

It is a readable bar code based on one-dimensional bar code. The equipment scans the two-dimensional bar code, and the information contained in it can be obtained by identifying the binary data recorded on the length and width of the bar code. Compared with one-dimensional bar code, the data recorded by two-dimensional code is more complicated, such as pictures and network links.
