You Work For A Grocery Chain That Always Has Many

You work for a grocery chain that always has many customers in the stores. To facilitate and speed checkout, the company wants to develop self-service checkout stands. Customers can check their own groceries and pay by credit card or cash. How would you design the checkout register and equipment? What kinds of equipment would you use to make it easy and intuitive for the customers, make sure that prices are entered correctly, and ensure that cash or credit-card payments are done correctly? In other words, what equipment would you have at the checkout station? In your solution, you can use existing state-of-the-art solutions or invent new devices.
