let us know how it goes as soon as you get there
The product has arrived. I can only add 1K rfid cards (cards with default key FFFFFFFFFFFF).
I need to install Mi fit application and open an account in China region for use NFC feature.
As a transportation card that cames default in Mi fit for adding to band, there are companies that only serve in China. I can't add other transportation companies. You can check balance, details etc.
You can add the NFC transportation card in your city like a normal Rfid card, but the "read-write key" must be FF....(12xF). You can not check the balance, details and others on Mi fit.
It is not possible to "add-edit-copy" a NFC card with any application other than Mi fit.
As it stands, there is no big difference. Sometimes I wish I had the global version. It doesn't have good features for the money I pay too much.
