Abstract
A personal digital ID device provides a digital identifier to a service for a predetermined duration in response to user interaction. The user interaction may include a button press. The personal digital ID device may be in the form of a bracelet, a key fob, or other form factor. The service may be provided by a mobile device, in the cloud, or elsewhere.
Claims18
A personal digital ID device comprising:
- a crypto/cipher engine having at least one digital identifier;
- a button accessible to a user of the personal digital ID device;
- a motion sensor to allow for user authentication when the personal digital ID device undergoes a predefined motion;
- a near field radio to communicate with a point-of-sale device;
- a non-near field radio to communicate with a mobile phone;
- and
- a processor coupled to the crypto/cipher engine, the button, the motion sensor, the near field radio, and the non-near field radio, the processor configured to validate a user through motion of the personal digital ID device and to turn on the non-near field radio for a predetermined duration for communication with the mobile phone in response to user interaction with the button;
- wherein the crypto/cipher engine makes available the digital identifier to perform authentication with a cloud service in communication with the mobile phone while the non-near field radio is on, and the crypto/cipher engine makes available the digital identifier using the near field radio to perform authentication with the point-of-sale device.
