The Postal Savings System is a financial service offered by postal services, allowing individuals to save money securely. It was established to encourage saving among the public and provide a safe place for deposits. Customers can open savings accounts at post offices, making it accessible to people in both urban and rural areas. This system often offers competitive interest rates and is backed by the government, ensuring the safety of deposits. Many countries, including the United States and Japan, have implemented their own versions of the Postal Savings System, promoting financial inclusion and stability for citizens.
