List of painpoints that the original design caused

Adding restaurant rewards is absolutely not user friendly. 
Every time someone wants to use the rewards for a free chips and salsa or something, the server has to explain it to the guest. I have also had to get a manager almost every single time because when you try to apply the reward to the bill on the presto, it will say that the coupon “has already been redeemed” 

The way that the presto asks for donations is not ideal. 
Chili’s wants to get donations for St.Jude’s children’s hospital but it comes up as the first screen before the user pays. The screen gives the user 2 options, yes or no, thank you. 

If a server is in a hurry to make sure the guest see’s their bill, they will 100% skip this screen by hitting the “no, thank you” button immediately so that the guest can see their bill. 

This keeps the company from getting donations. I would suggest that the screen be after the tip but before the survey. I’ll do more research on better ways to ask for donations here.

The Coupon scanning is not helpful
Guests do not usually have coupons to scan, they are coupons with code that servers need a manager to put into the POS system. This process is not helpful at all. 

The coupon screen should allow you to input your coupons manually AND include a scanner AND find another way for the user to redeem coupons. Think kohls cash or all the coupons they give customers.

Users think that the St. Jude donation screen is the tip screen 
This issue causes hard working servers to lose their tip, but also if the user catches the issue in time - the wre orker needs to grab a manager to take the St. Jude donation off of the bill. 

The tip screen comes up after the payment is made
This is very confusing for users and they are constantly asking me where they would add the tip to the total. This tip screen coming up after payment is not helpful because a lot of users anot inclined to tip after they've already paid.

Presto flex will come with a sensor that you can attach to the table. This will automatically attach the device to a table number based off of the tables range. I would say that the range should be the length and width of the table.
Pain point here is the servers/bartenders have to change the table number every single time they move the presto to another table and the process is that you hold down your finger in a secret spot and then press 4321 and then the green button and then you put in the table number and then you hit exit. What a time wasting process. 

Presto flex is absolutely not user friendly for older customers or anyone who is not computer savvy. 
I have to set up the presto for my older customers  99% of the time 

Presto flex gives the user 3 payment options, Tap/insert/swipe
This needs to make more sense for the people who are not tech savvy. It would be helpful if the user knew that if they want to pay with the tap option then they need to hold the mobile device or card with a chip in it in the middle of the presto screen for 3 seconds. It would also be nice if there were an option for the user to tell the server that they want to pay cash. I always ask cash or card and then the user says card but they decide midway that they want to use cash instead - they leave the cash on the table and leave.

Users accidentally buy table entertainment all the time
I can’t even tell you how many times people say “oh those games aren’t free?”, or “$2.99 is too much money for that crap, how do I take it off my bill.” or “I didn’t know it would be $2.99, I thought it would be 99 cents.” or “my kid accidentally bought the games, can you take it off my bill?” 

There has got to be a way to sort out this table entertainment mess

Brainstorming

I found The following devices to be very user friendly for older users. The Grandpad and Facebook Portal were specifically made for the less tech savvy older generations to connect with their loved ones in a much easier, more straight forward way.  These interfaces inspired my bigger button choices.

Based on the research that I have done on products that users above the age of 50 approve of- have found that they do enjoy the Amazon Echo Show and the GrandPad because the User Interfaces are a bit larger and are way easier to navigate.

The hardest thing for me to do was to try and find the balance between a playful interface for children to play games and a serious interface for adults to pay the bill.
