Can WeChat friends see it by scanning the code at the hotel?

I do not see any at all. Wechat scanning code is to scan the QR code provided by the hotel to check in at the front desk or room of the hotel, which has nothing to do with whether WeChat friends can see it. If you scan the QR code provided by the hotel, you will jump to an interface after scanning, and some check-in related information may appear, such as room number and check-in time. This information will only be displayed in your own WeChat account, which is invisible to WeChat friends.
