Bank

 refers to currency storage in Ragnarok Online and Ragnarok Online II. To check your personal, you simply refer to the UI display in the character's information window in RO or the menu bar in RO2.

Ragnarok Online
In RO, each character can only hold up to 2,147,483,647 Zeny in their. This is due to the game's programming only allowing the maximum number for a 32-bit unsigned integer. An in-game storage was implemented in Episode 10.2 as an actual  in the city of Lighthalzen. This allowed players to deposit and withdraw Zeny if they reach their limits on their characters. It is unsure if the storage was character-bound or account-wide, nor is it known how much the  storage can hold. Unfortunately, glitches with the system caused Zeny to disappear, prompting the Lighthalzen bank to be disabled indefinitely. Instead of being fixed, the storage was simply abandoned by the developers. As a result, the original storage system was never implemented in any other city (although buildings that would be s still exist).

In 2013, the character-bound became linked to all other characters on the same account, allowing it to be account-wide. However, it can only hold the max amount of Zeny that a single character can hold.

Ragnarok Online II
The personal in RO2 is displayed in the game's menu bar underneath the inventory bags. It is unknown what the maximum amount of Zeny and Rupi can be stored on each character.
