HOW USEFUL ARE THESE 2 NEW OPTIONS:
The Wechat ID change will be very useful for those who want to change their IDs and make them more professional or more personalized. This gives them the freedom to do so.
Secondly with the change in the Wechat Pay regarding money transfer, it will ensure security because you will know the other person number from which they can be traced as the mobile number can ensure their identity and authenticity thus improving the transfer of funds.
Therefore this will reduce the chances of online fraud. This will make the Wechat eco system more secure.
