A coupon/voucher dispenser is a device or machine that automatically dispenses coupons or vouchers to customers. These coupons or vouchers typically offer discounts or special deals on products or services. The dispenser is often found in retail stores, restaurants, and other businesses as a way to attract and reward customers. It works by scanning a barcode or entering a code, which then prints out the coupon or voucher for the customer to use at the time of purchase. This convenient and efficient method of distributing coupons and vouchers allows businesses to easily promote their products and services while providing customers with valuable savings.
