The Android environment is really cool,
we have access to lots of sensors the end user paid for,
including a GPS, microphone, camera, orientation sensor,
magnetometer, and more. But to the practical minded,
it is the ease of gathering input and having those input
sent wireless to backend devices that is of most use.
These are the pieces to a bigger puzzle,
such is the nature of software development.
After getting myself comfortable with the Android platform with the exercises done in App Inventor
and learning the new-to-me IDE that is Eclipse, it is time to develop something more revenue focused.
A few clients of mine runs restaurants, and that's the first area where technology has and can really make a difference.
fast food style koisk systems are now generally in use to place orders from the wait staff's console to remote printers in the kitchen,
but you still see the waitress writing on a paper pad next to your table, then walk over to the console to tap in the order.
In this mobile enabled world, there is really no reason to do that, the wait person should be able to take out a mobile
device, tap out the order as she takes it from the customer (maybe the customer can even do it herself on her own device)
then the order can immediately be sent to the cash register (for payment and accounting function) and the kitchen monitor.
(touch screen enabled, to allow the chef to tap clear the dishes that are done and ready for server delivery pronto)
An optional chromecast enabled big screen can then cycle the currently ordered dishes on the wall or waiting area depending on the setting.
(We all had the experience where we see what the next table is enjoying and ordered the same thing.)
Screenshot and QR and
link to the current build, item names are in chinese, when you tape the item, it shows up on the server, which will
be a POS register that does accounting, adding total and calculating tax, et cetera.
Yeah, the big red button sends you to the wrong php.
The order form was modified from code in a text book.
just wanted to try things out here.
A cash register for the 21st Century.
A simple php script. The intent was to use any web
capable display to act as cash register output
for easy POS customer viewing. It will act as a back
end for a Android Enabled POS input. The link is to
a random amount generator that updates every 15 seconds
without the Android frontend,
just for R&D display adjustment purpose.
The billboard fonts are hand made using ASCII.
It should be possible to direct the output to
a text only terminal.
The backend to the
functional Android app is
to see it work without installing the app,
just change the amount after the = to whatever you want.
