Basically, it is not allowed in the whole country. It is nonsense to say that bus cards can be recharged online or by banks.
Because the bus card is in the form of a magnetic card, not the same record form as the bank card we use, that is, the card you currently hold is a memory card.
There is no internet connection, and you need magnetic contact to recharge, which means that your bus card can't be recharged remotely.
Because he can't accept remote data, and the bus card reader can't accept data remotely.
