1. A server device for discovering smart card slots in a client 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 plurality of smart card slots;
using the smart card connector parameters, iterating through the plurality of smart card slots, over the Bluetooth connection, by interrogating 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.
