This technology would be awfully hard to beat.
A new Apple patent could lead to an eventual iOS update allowing users to rely on their heartbeat to unlock an iPhone, Apple Insider reported.
The technology already exists within the Apple Watch — which monitors heart rhythm through an electrocardiogram (ECG) app.
And, the outlet noted, heart patterns are already being used to open devices in some cases.
For example, instead of typing in a Mac password, an Apple Watch user can take a quick and easy ECG to open up their laptop — as well as receive authentication to open other devices, too.
As long as the watch is fully fastened to the top and bottom of a person’s wrist, simply opening up the ECG app will get the job done.
The new patent, however, is for an iPhone that can read a person’s heart rate — from the user normally handling the phone.
Then, the iPhone’s exterior would turn into a heart rate reader.
Additionally, the patent gets into how an ECG could be used to determine the “mood” of a user, according to the outlet.
One way this could be done is by examining a person’s heart rate to suggest a song of equal beats per minute.
The technology could then be used to speed up or slow down music as the user works out.
