you are partially correct in the sense that whenever you use your card, it is instant with no wait time.
however you are also wrong because , as some ppl already commented, the transactions/balance will be synched with the server.
fyi, it is possible to top up using ATM machine but you have to physically place the card on the ATM to update the balance in the card.
why they dont allow internet reload ? reason is because it is physically impossible for users to update the balance in the card.
summary: balance is stored in both card and server.
I don't think they're so daring as to not store some details in their own servers, they need to keep track anyway.however you are also wrong because , as some ppl already commented, the transactions/balance will be synched with the server.
