How does a Coinstar kiosk work?

A Coinstar kiosk is an automated machine that allows users to exchange coins for cash or vouchers. It works by the user pouring coins into the kiosk's tray, which then sorts and counts the coins. The kiosk provides a receipt or voucher for the total value, which can be redeemed for cash or used for other purchases. This process is quick, convenient, and eliminates the need to manually count and sort coins.
