Fingerprint sensors are all the rage in biometrics now, but they can get so…schmutzy. But you know what’s a lot harder to gunk up? The Bionym Nymi bracelet, which uses not your fingerprint, but your pulse as a biometric security key. The Nymi is still a prototype, but Bionym says it will pair with smartphone apps to unlock things like your car and electronic wallet.
The company reminds us that passwords can be hacked, fingerprint sensors can be fooled, and car keys can be stolen. But our pulses are more secure. You authenticate Nymi by touching your finger to the bracelet, and dual electrodes hidden within the clasp capture your pulse’s unique waveform. That’s the pitch, at least.
