The system is as follows:
When you visit, for example, Santiago, the capital of Chile, in the menu of this city, the option appears: Visit the South American bank. (you can also enter the scene, from the city center)
When you are inside, there will be 7 characters, 2 gentlemen, 2 ladies, a traveler and a provocative woman (this woman is also in the tavern) and the banker. With this banker, you will have to talk to get to the bank's presentation.
In this window, you will see your personal data (name, the cash you have, Deposits you have made, your debt and your honor), you will also see an interface for deposits (deposit and withdraw money) and loans (request money and return it). To assign amounts, you must move the bars or put the amount in the appropriate slots.
When you make a Deposit, after a few days you will be able to receive or earn interest. On the contrary, if you apply for a Loan, you will be notified of your debt within a few days. You will be charged interest for said loan, which you can pay at the time of being notified. If you do not want to pay, you can also add that interest to the debt. If you do not want any of the 2 previous options, you can choose the option "I do not want to pay", you must be careful, because you will go to prison.
If you go to prison, you will be notified of this event and after some time, you will need to talk to the guard for your release. (interest is not applied to the debt, but honor is lost).
Finally, you can also see at any time of the game,
the Bank report (statement of account), through the reports menu.
That's all, any question, you know you can do it right here.
