Create an app to allow artists and small businesses to accept payments using their Android or iOS device when they are face-to-face with their customers.

Oh, and by the way, it needs to use the existing data from the artists' website.
 

We built a mobile app that processed payments using a credit card reader from CardFlight (www.cardflight.com).
Next, read the inventory and prices from the artist or small business owner's website
We submitted the transaction through Stripe (www.stripe.com).
and finally, we stored the order on our servers in the cloud using an optimized API.
