One YC-backed startup is betting that fingerprints and other forms of biometric identification may be the payment method of the future though. Called PayTango, they're partnering with local universities to offer a quick and easy way for students to use their fingerprints to pay instead of credit cards.
"Samsung's new Galaxy S5 arrived with an unexpected and underhyped feature. Like the iPhone 5S, it came with a fingerprint reader, but this reader plugs directly into PayPal, which in turn connects you to dozens of different payment systems. It's a clever trick: instead of a password, all you need is a fingerprint, carrying you through the entire web. If it catches on, soon you won't need a password at all."
"with nothing more than this anonymous location data, someone who wanted to badly enough could easily figure out who you are by tracking your smartphone. Patterns of our movements, when traced on a map, create something akin to a fingerprint that is unique to every person."
"A wristband dubbed Nymi confirms a user's identity via electrocardiogram (ECG) sensors that monitor the heartbeat and can authenticate a range of devices, from iPads to cars. Developers at Bionym, the Toronto-based company that makes the device, say the peeks and valleys of an individual's heartbeat are harder to imitate than the external features of biometric systems, like fingerprints or facial recognition."
