Abstract
A method includes outputting with a first reader, presence signals to first smart devices, receiving responsive ephemeral ID signals, determining a first authorized device in response to the ephemeral ID signals, providing an ephemeral ID signal of the first authorized device to a second reader, directing a first peripheral to perform a user-perceptible action in response to the first authorized device, outputting with a second reader device, presence signals to second smart devices, receiving responsive ephemeral ID, determining a second authorized device in response to the ephemeral ID signals from the second smart devices, receiving the ephemeral ID signal of the first authorized device, determining a third authorized device in response to the ephemeral ID signal of the first authorized device, and directing a second peripheral device to perform a user-perceptible action in response to the second authorized device or the third authorized device.
