Currently, the process involves physically going to a store, navigating aisles, and standing in line to check out. My goal is to find a way to streamline and simplify this process, potentially through the use of technology. The concept of grocery shopping has likely existed as long as humans have needed to purchase food and other household items. However, the process of grocery shopping has evolved greatly over time. Early grocery stores in the 19th century were small, family-owned operations that sold basic necessities. With the advent of self-service supermarkets in the 1930s and 1940s, customers were able to browse and select their own products, streamlining the shopping experience. In the late 20th and early 21 st centuries, online grocery shopping and home delivery gained popularity, allowing customers to shop from the comfort of their own homes. More recent innovations include the use of mobile devices for shopping and payment, and the integration of technology such as selfcheckout and inventory management system
