12. The personal digital ID device of claim 11 wherein the plurality of LEDs are located in a line on an exterior surface of the personal digital ID device.

13. The personal digital ID device of claim 9 further comprising a flexible housing in a bracelet shape.

14. The personal digital ID device of claim 13 wherein the flexible housing includes a connector to allow the bracelet shape to be open or closed.

15. The personal digital ID device of claim 14 wherein the connector includes electrical contacts to disconnect the battery when the bracelet shape is open.

16. The personal digital ID device of claim 9 wherein the processor is configured to report the battery charge level in response to one press of the button.

17. The personal digital ID device of claim 9 wherein the processor is configured to report the battery charge level in response to two presses of the button.

18. The personal digital ID device of claim 9 wherein the processor is configured to report the battery charge level in response to a button press lasting longer than a predetermined threshold.

19. A personal digital ID device comprising:

a crypto/cipher engine having at least one digital identifier including one or more shared secret keys;

a button accessible to a user of the personal digital ID device;

a near-field radio;

a non-near-field radio; and

a processor coupled to the crypto/cipher engine, the button, the near-field radio, and the non-near-field radio, the processor configured to turn on the near-field radio and the non-near field radio for a predetermined duration in response to two pushes of the button;

wherein the crypto/cipher engine makes available the one or more shared secret keys to perform mutual authentication with a cloud service.
