If a forged note is deposited at a bank, it will be impounded in the depositor's presence, and an acknowledgment receipt will be issued. The bank hands the counterfeit note over to local police, resulting in the depositor losing the note and potentially facing arrest. To avoid such situations, it is important to learn how to identify counterfeit notes, with specific features like watermarks, color-changing numerals, and specialized printing techniques to look for on legitimate currency.
