Biometric startup Token has developed a ring with an embedded fingerprint sensor that the firm is positioning as an solution for payments, access and more.The ring is made of thick metal and plastic, but inside it has an optical sensor, a fingerprint sensor, and NFC and Bluetooth along with a chip with a secure element inside. When you slip on the ring – scanning your fingerprint in the process – Token will continuously verify your identity. Take the ring off and the connection is broken, meaning anyone else who attempts to use your Token will be thwarted without your fingerprint.The device's secure element means that your credentials are stored locally, not on a server somewhere, similar to how Apple handles your credit card information with Apple Pay.Due out later this year, the ring is designed as a stand-in for everything that unlocks your life: credit cards, transit passes, car keys, workplace access cards, and even passwords.
