First of all, like you, I am also a user and beneficiary of the smart APP in September.
Secondly, I only have September intelligence in my hand so far, because of your safety. I contacted a friend who works in a bank and said that September technology is the safest model.
Finally, for people with poor living and economy like us, having such a tool can solve people's worries, and it is free, which really makes people feel that only a few people know our difficulties.
These are my personal feelings, which may not be to your taste, but be sincere!
