Abstract

A wireless key device is configured to execute a digital credential management method to manage a plurality of digital credentials. According to this digital credential management method, the wireless key device polls an access terminal for an access terminal identification which uniquely identifies the access terminal. The wireless key device identifies a filter based on the access terminal identification, and selects a subset of the plurality of digital credentials based on the filter. The wireless key device renders a list of the subset of the plurality of digital credentials on a display, receives a user input selecting one of the subset of the plurality of digital credentials, and transmits the selected credential to the access terminal.

Claims

1. A wireless key device comprising:

a wireless transceiver and antenna configured to communicate wirelessly with an access terminal;

an input device configured to receive user input;

an output device having a display; and

a processor configured to;

poll the access terminal via the wireless transceiver and antenna for an access terminal identification which uniquely identifies the access terminal;

identify a filter based on the access terminal identification;

select a subset of the plurality of digital credentials based on the filter;

select a first digital credential from the subset of the plurality of digital credentials; and

transmit the first single credential to the access terminal via the wireless transceiver and antenna.

2. The wireless key device of claim 1, wherein the selecting a single credential comprises:

rendering a list of the subset of the plurality of digital credentials on the display; and

receiving a user input via the input device, the user input selecting one of the subset of the plurality of digital credentials.

3. The wireless key device of claim 1, wherein the processor is further configured to select and individually transmit additional credentials from the subset of the plurality of digital credentials, if the first credential is not accepted.

4. The wireless key device of claim 1, wherein the selecting the single credential comprises selecting a favorite or previously user-selected credential from the subset of the plurality of digital credentials.

5. The wireless key device of claim 1, wherein the wireless transceiver and antenna are a near field communication transceiver and antenna, respectively.

6. The wireless key device of claim 1, wherein the processor is further configured to retrieve at least one among the plurality of digital credentials from a server.

7. The wireless key device of claim 6, wherein retrieving at least one among the plurality of digital credentials comprises retrieving the selected credential upon receiving the user input.

8. The wireless key device of claim 6, wherein retrieving at least one among the plurality of digital credentials comprises retrieving the subset of the plurality of digital credentials from a server after selecting the subset of the plurality of digital credentials.

9. The wireless key device of claim 1, wherein the processor is further configured to ascertain a location via GPS, and wherein the at least one among the plurality of digital credentials is retrieved in response to the ascertained location falling close to a known location of the access terminal.

10. A user authentication system comprising:

an access terminal configured to receive a first digital credential for validation; and

a key device comprising a wireless transceiver, a credential memory configured to store a plurality of credentials, and a processor configured to;

poll the access terminal via the wireless transceiver for an access terminal ID which uniquely identifies the access terminal;

identify a filter based on the access terminal ID;

select, from among the plurality of digital credentials, a subset of digital credentials including the first digital credential, based on the filter; and

transmit the first digital credential to the access terminal via the wireless transceiver.

11. The user authentication system of claim 10, wherein the access terminal ID specifically identifies the first credential, and the selected subset of digital credentials includes only the first digital credential.

12. The user authentication system of claim 10, wherein the access terminal ID is a near field communication or radio frequency identification tag.

13. The user authentication system of claim 12, wherein the access terminal operates in a tag mode, and the wireless key device operates in a reader mode.

14. The user authentication system of claim 10, wherein the access terminal and the wireless key device both operate in peer-to-peer mode.

15. The user authentication system of claim 10, wherein the access terminal is a wireless lock.

16. The user authentication system of claim 10, wherein the access terminal is an electronic banking terminal.

17. The user authentication system of claim 10, further comprising a screen and an input device, and wherein the processor is further configured to:

render a selection display of the subset of digital credentials on the screen; and

receive a user input via the input device, selecting the first digital credential from among the subset of digital credentials.

18. The user authentication system of claim 10, wherein the access terminal directly communicates only with the key device and other key devices.

19. A method of managing digital credentials for a wireless key device, the method comprising:

retrieving an access terminal ID from an access terminal, the access terminal ID uniquely identifying the access terminal;

identifying a filter based on the access terminal ID;

selecting a subset of the plurality of digital credentials based on the filter;

rendering a list of the subset of the plurality of digital credentials, on a display;

receiving a user input selecting one of the subset of the plurality of digital credentials; and

transmitting the selected credential to the access terminal.

20. The method of claim 19, wherein retrieving the access terminal ID from the access terminal comprises communicating with the access terminal by means of near field communication (NFC), and wherein the access terminal ID is a NFC tag.

21. The method of claim 19, wherein retrieving the access terminal ID from the access terminal comprises communicating with the access terminal via Bluetooth or Wi-Fi, and wherein the access terminal ID is a MAC address.

22. The method of claim 19, wherein retrieving the access terminal ID is ascertainable from a bar code or label on the access terminal.

23. The method of claim 19, wherein the access terminal directly communicates only with the key device and other key devices.
