Tencent official explanation:
The validity period of the WeChat group QR code is 7 days (from the time when the QR code is generated, the expiration time will be displayed below the QR code). When scanning after expiration, it will prompt "QR code has expired".
The official answer given by Tencent is 7 days. After seven days, the QR code will expire.
Relevant persons said:
Wechat is a social platform with strong relationships. In order to avoid the long propagation time of QR code, members in the group can't control the user identity and joining time, which is unpredictable, so the validity period is limited. After the expiration date, even if the QR code is available globally, you can't join the group.
As for a few days, it must be nine Niu Yi Mao, so don't worry too much. 7 days, 10 days, 15 days, 1 month is actually ok. The longer the time, the greater the impact on the group, and the problem of a few days is not big.

Question 3: How to set a long-term effective WeChat QR code? Wechat QR code is valid for a long time, hope to adopt it!
Question 4: Is the QR code of WeChat collection valid for a long time? No, the QR code of the personal WeChat account for collection is only valid for 3 minutes, and it will be invalid immediately after it is exceeded.
However, enterprises or institutions that apply for WeChat payment merchants can generate long-term and effective secondary friends.

Question 7: How is the QR code of friends circle effective for a long time? The latest version of WeChat can be scanned and identified by directly pressing the QR code.
Open discovery-circle of friends; Click the camera in the upper right corner, select the QR code from the photo album, enter the text and publish it;
In the published circle of friends, long press the QR code, select Identify QR code in the pop-up menu, enter WeChat scanning, and automatically identify the QR code.
Question 8: How long is the validity of WeChat QR code? It stands to reason that the WeChat group has always been there, and the corresponding QR code has always been there. However, there are the following special cases. Q: When scanning the code, do you prompt that the QR code has expired? A: There are two possibilities. First, the uploaded group was not created by the submitter, and the publisher later withdrew from the group, resulting in the invalidation of the group QR code; Second, in order to prevent malicious scanning and reduce the system load, Tencent's member users scan too much and too fast. Scanning for more than 20 times in a row will prompt "QR code has expired", which is a normal prompt. After a period of time (about an hour), you can scan it again. If you don't believe me, you can test it with another mobile phone WeChat. Prior to this, when scanning too fast and too much in a period of time, Tencent prompted "system error", so many people thought it was a problem with WeChat system. Now Tencent has avoided this problem and changed the prompt to "QR code has expired", avoiding its own drawbacks.
Question 9: Can I join the WeChat QR code after it has expired? The QR code shared by WeChat group has a date. If it expires, you can't continue to use it. You need to share a new QR code.
Question 10: How to make a long-term and effective WeChat QR code? The principle of WeChat QR code collection is very simple, that is, by creating a receipt QR code, payment users can scan and complete the payment, whether it is face-to-face payment or payment between WeChat friends.
After entering the WeChat QR code collection setting interface, enter the collection amount first, and then click OK below.
After clicking OK, a payment QR code will be generated. If the payment is made between friends nearby, the payer only needs to scan the QR code on the mobile phone to collect the money.
If the payment is not made by friends around us, but by WeChat friends online, we can click on the screen capture phone or long press the QR code, and then click the "Save" picture that pops up at the bottom, so that the QR code can be saved to the phone photo album.
When my friend receives the first QR code of WeChat, I can scan it directly to complete the payment, and then I will see a prompt "There is a security reminder window" and click "Received".
Finally, wait for WeChat friends to complete the payment, and then complete the collection of WeChat QR code.
