Thanks for all of the comments. Again the construction criticism is appreciated. I understand that no idea is originally. Is anyone familiar with E La Carte, Ziosk or iMenu? :-) They helped plant the seed for the idea I have now. I went to a roadside restaurant when I was traveling in Orlando, FL and they had a tablet you could order from on the table. My server that night became much more of an entertainer. She told jokes and talked our table up and I felt "wow" this person is really working hard for my tip. I loved it. When the technology does the boring work, it let's people be people. :-) The experience I had that night was amazing.
The issue I found with most of these devices is that, although they can take orders....that's pretty much all they can do. Now what if that device helped me leave a review on yelp, google, or urbanspoon? The review would be optional, but if one leaves a review (of any kind) he or she could receive a discount on their next visit. What if the device could suggest a tip to be given based on the review that's left. I'm just throwing out examples here, but let's say you leave a 5 out of 5 star review, the device could suggest a tip of 30% (which in my book is exceptional service). If it's 3 out of 5, it could suggest an average tip 15% and so on and so on. Again this would all be optional as the customer would have the right to leave his or her own tip or no tip at all.
For some reason, people love taking pictures of food with Instagram. I don't know why, but it happens. The device could allow customers to upload their photo of their dish. Others could vote on the photos and the highest voted photo would be used as the photo to represent that item on the menu. Let's be honest. The items that we see in those menu pictures don't always represent what you'll receive. :-)
All of this stuff is nice, but how do restaurant owners make money from this? Ideas like these are a waste of time unless there's some sort of tangible return on the investment. Well the money comes from the analytics. That's the secret sauce. This new POS system would constantly collect data and it would turn that data into useful information. Let's say your establishment is located directly in the path to a sports stadium. On game nights your place is full of people. The system would correlate game day activities with higher sales. It could suggest to the owner a price raise of 2% on the most popular items for game days. Maybe there's someone who stocks up on ice cream ingredients, but sells very little ice cream in November and December. The system could correlate the low sell of ice cream with cold temperatures. It could then suggest not buying ice cream ingredients when there is a forecast of very cold weather an extended time or it could suggest a lower price on the ice cream.
As a customer, I could use the analytics so I wouldn't have to remember what I ordered last time. I hate that. There are restaurants where I visit once every 4-5 months. I can never remember what I liked and what I didn't like on my previous visit. I would love to be able to look up the last meal I ordered from those establishments. Based on food that I like, I'd want it to suggest new things for me to try. "Hi D, based on your previous purchases, I can tell you enjoy seafood so how about trying Establishment XYZ's Super Salmon." For those who enjoy eating gluten free dishes, it could automatically remove every dish from the menu that contains gluten. It would make the ordering process personal and simplify it for those with dietary constraints.
I'm definitely going to take the feedback that hpx, tbone, CCinNJ (sometimes old habits are hard to change), and MetroplexJim left me and will continue to shape the idea. I'll also follow up on any links or external resources you all suggested. If you come up with other ideas, thoughts, feedback, or criticism, I'll continue to listen and incorporate them. Thanks again!
