The term "paisa" refers to a monetary unit used in several South Asian countries, including India, Pakistan, and Nepal. It is often a subdivision of the main currency, such as the Indian Rupee or Pakistani Rupee, where 100 paisa equals one rupee. The paisa is commonly used in everyday transactions, especially for small purchases. Historically, the paisa has roots in ancient Indian coinage and has evolved over time. In modern usage, coins and notes in paisa denominations are less common, as many transactions are rounded to the nearest rupee. However, the paisa remains an important part of the region's economic history.
