This app is a pretend payment terminal for kids.
Important: it uses only fake money. No real money is charged, moved, or spent in this app.
It has two modes. In the first mode, any valid NFC card or tag (including real payment cards) is treated as a successful pretend payment, and top-up is disabled.
In the second mode, you can set up a regular NFC tag as a fake card for this app, choose its pretend balance, and simulate payments by deducting that fake balance.
The first mode is best for quick pretend play, while the second adds structure and helps kids practice money concepts safely.
