2. Abstract המעבדה למערכות ספרתיות מהירות High speed digital systems laboratory 2 People around the globe are spending great dill of their quality time doing shopping. The main aim of this project is to save some of this precious time. The mean of achieving this goal is building a smart, Computerized, wireless platform for supermarket carts. This project is a prototype for such a platform which, Basically, have the following abilities: Ability to communicate with the customers. Ability to communicate with a main server. Ability to identify products. Ability to manage shopping list and calculate total price.
