The app a dealer in the field uses to take card payments with a phone.
Summary
Tap the card on the phone and the payment is done. Even if the connection drops, nothing is lost and no payment is taken twice.
01
Need
Dealers in the field did not want to carry a separate POS device.
02
Solution
I built an app that turns the phone itself into the payment device.
03
Result
The cashier never has to ask whether it went through.
Result
- 01The phone becomes the POS device
- 02Payments survive connection drops
