Credit cards are used in a unified national standard regardless of regions. There is no such thing as high cost in different places. It does not have the storage function of a savings card. There will be a handling fee for withdrawing the money you put in. It's good to take this function down for emergency use. I suggest that you do not need to apply for a new card in another place, but apply for another savings card. Spend with a credit card and save with a savings card, so that you can participate in activities such as credit card points at the same time.
