It’s not quite the same as using Touch ID which relies on fingerprints, but since embedded a fingerprint sensor into the device isn’t quite practical in terms of size, what else can Apple do? According to a patent discovered by AppleInsider, it seems that Apple could be considering using vein patterns as a means of identifying users.
The patent describes how a pulse oximeter could be used to identify biometric characteristics of a user’s vasculature, thus ensuring that the wearer of the watch is who they say they are. By introducing such a feature, it helps Apple reduce the reliance of the Apple Watch on the iPhone, something that users have been asking for.
The idea of using veins as a means of identification isn’t new. Recently at CEATEC 2016 in Japan, Fujitsu showed off a palm vein scanning technology that authenticated users when it came to making mobile payments. However given that this is only a patent, there’s no telling if Apple plans on implementing it into future Apple Watch devices.
