My First Wallet #Bankathon16 #

This is the prototype developed during the “Bankathon16” hackathon hosted by INSO (Technical University of Vienna). It was a 2 day event, 3 developers worked on the project. This project achieved 2nd place in the ranking.

Use Cases #

This is basically a specialized payment and send money app with added functionality to provide this service to a minor with the parents supervision.

Adding children #

An envisioned app for the parents contains an administrative UI where a child can be registered. To do this the parents mobile phone communicates through NFC with the child’s app, automatically registering it to the parent.

Sending money #

Parents can send money and set restrictions on how the money can be spent (e.g. max daily amount, specific shops, etc.)

Pay with children’s App #

The app can be used to pay at NFC payment terminals. It is implemented to work with simple NFC tags, although HCE is a possible real world solution for this.

Save money #

To learn financial literacy, a child can set a saving goal to set a certain amount of money aside whenever it feels like it. This amount won’t be able to be spent through the payment function. A parent has to release the money.
