Automated Postal Centers (APCs) are self-service kiosks found in various locations, such as post offices and shopping centers. They allow customers to send and receive mail, purchase postage, and access other postal services without needing to interact with a postal worker. These machines are designed to streamline the mailing process and reduce wait times. Users can pay for services using credit or debit cards, and the machines typically provide a touchscreen interface for easy navigation. APCs are equipped to handle various tasks, including weighing packages, printing labels, and providing tracking information for shipments.
