A postage meter is a device used to print postage directly onto envelopes or packages. It allows businesses and individuals to send mail without needing to buy traditional stamps. By using a postage meter, users can weigh their items, calculate the correct postage, and print it instantly, making mailing more efficient. Postage meters are often used by companies that send large volumes of mail. They can be connected to the internet to automatically update postage rates and track mailing expenses. This technology simplifies the mailing process and helps save time and money for users, especially in busy office environments.
