The document proposes a mobile application called GroceryGuru that allows customers to scan grocery items with their phone as they shop and pay without waiting in checkout lines. Currently, the average shopping trip takes 41 minutes with 7-10 minutes spent waiting in line. GroceryGuru aims to reduce this wait time by enabling customers to scan items, view their virtual cart, and pay using pre-registered payment methods. The application would be universal across stores and offers a premium version with purchase analytics and loyalty rewards.
