POS System



A point of sale system, or POS, replaces what cash registers used to be. It is the place where a customer places an order and makes a payment for products or services in a store. POS helps retailers and store owners take their customer experience to a new level. Besides handling payments, POS systems can track sales, manage inventory, generate reports, and keep track of employee hours.


Understanding the Problem

Time Pressure
General users go through user flows at their own pace with virtually no time pressure. However, cashiers need to become familiar with the POS interface immediately to avoid long lines and upset customers. Therefore, the interface and user experience should be even more intuitive, coherent, and simple.
Complicated Navigation
Finding a product in the POS can be very difficult at times. Navigating through the system in search of a specific product can leave cashiers lost and frustrated. There are times when typing a name in the search bar is not an ideal solution, because the cashier may not know the exact name.


The Challenge

Curbngo’s store owners and cashiers were already familiar with handling incoming orders with food-runner tablets. The challenge was to integrate the food-runner software with a newly designed POS system with built-in functions like clock-in software, inventory management and cash register.



The Process

The first phase consisted of doing online research. My research included tutorials and walk-through videos from competitors in the same industry such as Lightspeed, Oracle, Square, Elo Touch. As per client’s request, my prototypes needed to have a split screen layout. The left side works as a food-runner, but becomes a receipt panel when the cashier starts to order. The right one assists the cashier to explore menus and categories and add items to the cart.
Then I developed several sketches, wireframes and designs for different functions: menu management, checkout screen, payment methods, etc. Using Invision prototypes, I tested various user flows on a POS device.

The Result

Suspendisse et quam vel orci accumsan porta. In aliquam leo sit amet elit volutpat posuere. Donec tristique vel lacus hendrerit tincidunt. Etiam tincidunt mattis purus, in malesuada dui elementum non. Suspendisse convallis nunc et eros imperdiet fermentum ut nec sem. Vestibulum consectetur nec quam eget vehicula. Pellentesque gravida ultrices ipsum a viverra. Aliquam semper pharetra lobortis. Pellentesque vestibulum est eu enim hendrerit, et porttitor nisl dapibus. Quisque eu justo mauris. Suspendisse rutrum, justo nec volutpat cursus, leo libero tempor augue, in elementum felis quam ut quam. Morbi porta nulla nec odio tempor interdum. Nulla facilisi. Pellentesque tempus, purus non congue tristique, risus magna viverra lorem, id tincidunt lorem justo maximus ligula. Aliquam placerat lacinia neque, quis sagittis justo.
