We’ve learned that Apple has designed a demo application specific
to the iPhone 5s demo units that will be found in Apple Stores and
Carrier stores. To test Touch ID, a customer can launch the demo
app. In this app, a customer can setup the device to recognize a
single fingerprint. When the setup process is complete, the
application will direct the user to place that fingerprint on the
Touch ID sensor on the Home button. The application will then show
that the Home button successfully read the fingerprint. Then, the
app will tell the user to place a different finger on the Home
button. The app will then show a red fingerprint outline to note
that the authentication was not successful.
Cool idea for a tough-to-demo feature.
