Abstract

Various systems and methods for providing discovering smart card slots in a device are described herein. A server device for discovering smart card slots in a client device may be implemented with a processor subsystem; and memory including instructions, which when executed by the processor subsystem, cause the processor subsystem to perform operations comprising: receiving, at the server device from the client device, over an established Bluetooth connection, smart card connector parameters, the client device having a plurality of smart card slots; iterating through the plurality of smart card slots; at each slot of the plurality of smart card slots, using a smart card protocol to attempt to access an application at each slot, the application pre-associated with the server device; and in response to identifying the application exists in a slot of the plurality of smart card slots, connecting with the application.

Claims (32)

1. A server device for discovering an application on a smart card of a client device, the server device comprising:

a processor subsystem; and

memory including instructions, which when executed by the processor subsystem, cause the processor subsystem to perform operations comprising:

receiving, at the server device from the client device, over an established Bluetooth connection, smart card connector parameters, the client device having a smart card with a plurality of applications stored thereon loaded into a smart card slot of the client device;

using a smart card protocol over the Bluetooth connection to attempt to access a particular application of the plurality of applications, the particular application pre-associated with the server device; and

in response to identifying the particular application exists on the smart card, connecting with the particular application.

2. The server device of claim 1 , wherein the smart card is an embedded Secure Element (eSE) smart card or a host card emulation (HCE) smart card.

3. The server device of claim 1 , wherein the smart card is a virtual smart card.

4. The server device of claim 1 , wherein the smart card protocol includes ISO/IEC 7816.

5. The server device of claim 1 , wherein the particular application is pre-associated with the server device when the server device is initially provisioned for field service.

6. The server device of claim 1 , wherein the particular application is a fine ranging application.

7. The server device of claim 6 , wherein the particular application implements ultra-wideband (UWB) technology to provide ranging data to the server device.

8. The server device of claim 7 , wherein the operations comprise negotiating, over the Bluetooth connection, UWB parameters for a UWB ranging session.

9. The server device of claim 8 , wherein the operations comprise establishing the UWB ranging session using the UWB parameters.

10. The server device of claim 1 , wherein the operations comprise:

disconnecting from the particular application; and

establishing an ultra-wideband (UWB) ranging session using data received from the application.

11. A method for discovering an application on a smart card of a client device, the method comprising:

receiving, at a server device from a client device, over an established Bluetooth connection, smart card connector parameters, the client device having a smart card with a plurality of applications stored thereon loaded into a smart card slot of the client device;

using a smart card protocol over the Bluetooth connection to attempt to access a particular application of the plurality of applications, the particular application pre-associated with the server device; and

in response to identifying the particular application exists on the smart card, connecting with the particular application.

12. The method of claim 11 , wherein the smart card is an embedded Secure Element (eSE) smart card or a host card emulation (HCE) smart card.

13. The method of claim 11 , wherein the smart card is a virtual smart card.

14. The method of claim 11 , wherein the smart card protocol includes ISO/IEC 7816.

15. The method of claim 11 , wherein the particular application is pre-associated with the server device when the server device is initially provisioned for field service.

16. The method of claim 11 , wherein the particular application is a fine ranging application.

17. The method of claim 16 , wherein the particular application implements ultra-wideband (UWB) technology to provide ranging data to the server device.

18. The method of claim 17 , further comprising negotiating, over the Bluetooth connection, UWB parameters for a UWB ranging session.

19. The method of claim 18 , further comprising establishing the UWB ranging session using the UWB parameters.

20. The method of claim 11 , further comprising:

disconnecting from the particular application; and

establishing an ultra-wideband (UWB) ranging session using data received from the application.
