Attending a movie night at my kid's school and waiting in line to pay for a pizza slice and drinks made me realized that there are many cases where you just want to buy fixed price items as quick as possible and obtain a receipt you can give to the person serving. Having contactless payments and printing a receipt speeds up the line and improves customer satisfaction. Multiple taps of the reader can accommodate for buying more than one unit.
What it does
It automatically accepts fixed amount payments and prints configurable receipts. Receipts can be event tickets, food and drink vouchers, instructions, etc.
How I built it
Using Android Studio to integrate to Square POS, and added bluetooth printing support.
Challenges I ran into
Having the Square reader not to timeout when idle.
Accomplishments that I'm proud of
Figured out how to keep the Square POS in a loop
What I learned
I learned about Square POS for Android
What's next for Tap to Buy
Promote and monetize.
