With its Pixel 4, Google introduced a new unlock method for the line: a series of secure face unlock sensors. To use the new face unlock method, developers must take advantage of Android’s biometric API, and the popular cash app Cash App has now added support for that on Pixel 4 and future devices.
In an update that was released in late June for Android users, the Cash App delivered some bug fixes and, as far as we can tell, not much else: changelog in the Play Store is essentially useless. The biggest change comes in the form of suitable support for the latest Android biometric APIs.
Cash app now supports “BiometricPrompt” API, which handles both fingerprints and facial unlocking systems. This means that there is a new user interface for biometrics, regardless of what you are using. For Pixel 4 owners, a PIN is no longer required to send funds through the Cash app.
The Cash app is just the latest in a growing list of apps that support this feature, but it’s definitely one of the biggest additions in recent memory. Personally, I hope PayPal will follow closely.
