RESULTS We tested PayFast by creating a mock restaurant and asking 32 participants to run through a bill payment using both a paper bill and PayFast. 91% of participants would prefer to use PayFast when dining out with a group. The time spent by wait staff handling a PayFast bill was calculated to average 40 seconds less than the time spent handling a paper bill. The most common comments we received from participants were: + No mental math or cell phones needed to calculate tip and split bill + Offers a simple way to split bill when using multiple credit cards + Saves tress by removing the paper bill and offering an receipt - Not apparent how to split a single item between multiple diners - Passing the tablet between diners slows the payment process down - Pages sometimes load slowly, depending on the available WiFi When given the option, 28% of participants choose to be added to the mailing list. This is compared to approximately 1% in local restaurants who opt into mailing lists via comment cards. Participants were asked to compare PayFast with the traditional paper bill in three areas: speed, ease of use, and fairness in splitting the bill. PayFast was preferred in all three. These results are shown in the graph below. B ETA T EST PROJECT GOALS  To create a tablet software that will allow restaurant patrons to easily and quickly view, split, and pay their bill without detracting from the existing restaurant experience.  To decrease the wait staff time and efforts consumed by processing bill payments.  To allow an opportunity for restaurant management to increase their communications with patrons by more easily collecting addresses. PayFast The Restaurant Payment Solution ABSTRACT Often times when dining out, large parties have difficulties splitting and paying their bill. Some people tend to consume more than others and processing separate checks is time- consuming and inconvenient for the restaurant staff. These issues stem from the rigidness of the paper bill checkout system used by restaurants today. PayFast solves these issues by replacing the paper check with a digitalized bill on a tablet device. The system allows diners to split and pay the bill in a variety of ways. Restaurants can process payments more easily and form a customer mailing list from the checkout process. While testing the system in a restaurant simulation, diners preferred using the PayFast system to the traditional paper bill and benefitted from quicker and easier checkouts. They were also able to split the bill fairly by paying for what each individual ordered. After integrating PayFast, restaurants can increase sales from higher table- turnover and improved customer relationships through their mailing list. Diners gain flexibility and leave happier when given more options in paying for their bill. The simplicity and elegance of PayFast provides these benefits without detracting from the overall dining experience.

Nothing has changed! The server will keep track of the tab in the existing POS system. Nothing has changed! Waiters would always carry around PayFast enabled tablets. When you ask for the bill, the waiter would pull the tablet out of his/her pocket and select your table. The PayFast software will communicate with the POS system and retrieve the details of your bill. You can view and pay your bill on the device using the PayFast interface!
