A money order is a secure payment method that allows individuals to send money without needing a bank account. It is purchased at various locations, such as post offices or retail stores, and can be used to pay bills or send funds to someone else. The buyer pays the amount of the money order plus a small fee. Once purchased, the money order is filled out with the recipient's name and can be cashed or deposited at banks and other financial institutions. Unlike personal checks, money orders are prepaid, making them a safer option for sending money.
