A new wearable digital wallet for your bitcoins will only allow you to spend the online currency after the device verifies your identity using your heartbeat.
The Nymi was developed by the Toronto-based tech company Bionym.
"People don't know where their bitcoin funds are stored, and who can access them. The Nymi's wallet application makes the answer clear: the wallet is physically stored on the Nymi. The Nymi's multi-factor system, including its ECG biometric, ensures secure bitcoin storage tied to the rightful owner," the company's chief cryptographer Yevgeniy Vahlis said in a release about the Nymi on Tuesday.
The website for the Nymi bracelet says "like a fingerprint, your heartbeat is unique."
Bitcoin is a virtual currency that was started in 2009, but has been gaining popularity in the past year. People are able to "mine" bitcoins online, or buy them using bitcoin ATMs and they can be used to purchase items or services.
