What is one function of a self-service kiosk in postal retail?

Self-service kiosks in postal retail are designed to enhance customer convenience by enabling them to perform simple transactions independently, without needing assistance from a postal employee. These kiosks typically allow customers to purchase postage, mail flat items, and complete other straightforward tasks, thereby reducing wait times and streamlining service.

This service is particularly valuable in busy post office environments, as it helps alleviate the burden on staff and allows customers to complete their transactions efficiently. While the other options involve more complex or operational aspects of postal service, the self-service kiosk is specifically focused on empowering customers to engage in simple activities at their own pace.
