Yes, you can share an account with another person for free.
It is perfect for sharing savings and common expenses without complications, conditions or commissions.
Both of you will be able to manage your money shared from your mobile phone with the same bnc10 application and from your computer with the Webapp where you will have both accounts (personal and shared).
This shared account works just like a personal account, except that the shared account does not have a physical card. But this is not a handicap to using the account, because you can pay with your mobile phone and virtual card.
The only requirement to open a joint account is that both of you must have a personal account at bnc10.
