배달 타자 is an Android application designed to simplify the ordering of food and beverages at Jamsil Baseball Stadium and Kia Champions Field. This user-friendly service allows fans to enjoy their favorite snacks without missing any game action. Key features include pickup orders, where users can pre-order items to avoid lines, and delivery orders that bring food directly to their seats. Additionally, the app offers a 'Quick Pick' feature for instant pickup items, enabling users to select and order products that are readily available.

The app also supports coupon management, allowing users to check and apply available coupons during their orders. While users may need to grant permission for notifications to receive updates on their orders, the app remains functional without this access. It operates on both Wi-Fi and mobile data, though users should be mindful of potential data charges if they do not have an unlimited plan. Regular updates are recommended for optimal performance.
