An electronic shopping cart, programmed with the help of a shopping cart software mostly occurs in terms of online-shops or e-commerce platforms. The customer picks an item in the online-shop he/ she would like to buy. As a result the choosen item appears in the virtual shopping cart. In order to finish the shopping process, the customer clicks on the shopping cart item (very often in the upper right corner of the online-shop) and therefore sees the content of the shopping cart including the quantity of items and the total sum. Besides the customer is able to add or delete items out of the shopping cart and to choose possibilities of shipping. By affirming the content of the cart the customer is passed forward to the stop ofbilling, e.g. via PayPal, where he/ she enters his/her financial data and finally affirms the whole purchase.
