I think Cartel Empire could add a proper bank check system available to all players. Players could issue checks directly from their bank account and use them for player-to-player transactions, purchases, business deals, or other large payments. The recipient could deposit or cash the check through the bank, while the system verifies whether the issuer has sufficient funds. This would make large transactions safer and more convenient, especially when players don't want to carry large amounts of cash. It could also include features like check history, pending/cleared status, expiration dates, and penalties for issuing checks without sufficient funds. This would add another useful financial tool and make the game's economy feel more realistic.
