How to associate wechat applet QR code to realize two code aggregation

I believe you have encountered such a scene in the parking lot , When entering and exiting the parking lot , Whether we use wechat or Alipay , Just scan the same QR code , Automatically identify and open the applet at each end , And bring it to the parameter parking lot id And channel id.

This method is generally referred to as QR code aggregation or “ One yard pass ” Ability , Especially wechat and Alipay App Its current , Have a large number of user groups and a large number of small programs , User scanning QR code App It could be either of the two , Or more App Any one of them , At this time, the user can scan the same QR code according to App It is very important to open the applet of the platform by itself .

The way of QR code aggregation

1、 Open the applet in the normal link mode

Ordinary QR code refers to the QR code generated by the developer after coding the web page links with tools .

Developers do not need to change the offline QR code , By setting association rules in the applet background , Associate the address of the ordinary offline QR code with the applet page , The user uses any App Scan the ordinary QR code of the address to open the applet and jump to the specified page .

In this way, the whole process will be cumbersome , But it is also the preferred method for most developers . Just take Alipay as an example , It is very troublesome to be compatible with wechat QR code , At least 7 A step , But also need to move to the code .

If you want your own App Able to run small programs , And the applet inside can use the same QR code as the wechat applet , There is a more convenient way . Just in your own App In the integration FinClip SDK Have the ability to run small programs , Next, you can make your own... By binding QR codes App Scan the QR code of wechat applet to open yourself App The applet in .

2、 Associated wechat applet QR code

First step ：

Sign in FinClip Management backstage

The second step ：

stay “ Applet management ” find ： My applet >> Applet details >> Third party management .

The third step ：

Click on “ Add QR code Association ”, Fill in as required “ Wechat applet APP ID”、“ Wechat applet APP Secret”、“ Wechat applet page path and parameters ”.

Complete this step and you're done , The QR code generated by the applet can be opened by scanning wechat , You can also use FinClip App Or own App Scan code to open .

Besides FinClip It can also realize the ability of small programs to reuse wechat login without moving the code , The method is consistent with the QR code of the associated wechat applet .

The above is the small program QR code aggregation or “ One yard pass ” Ability is the most convenient way , I hope this tutorial can effectively help small program developers more easily compatible with the existing offline wechat QR code , Realize online and offline linkage and efficient promotion of small programs .
