responsive to reception of the second identifier, reprogramming the programmable unit such that the programmable unit indicates the second identifier to the electronic storage media instead of the first identifier; and
subsequent to the reprogramming the programmable unit to indicate the second identifier, communicating with the wireless network through the wireless transmitter at a second unique address that corresponds to the second identifier.
10. The method of claim 9, further comprising:
presenting the first identifier on an electronic display of the paging device; and
responsive to reprogramming the programmable unit to indicate the second identifier, presenting the second identifier on the electronic display.
11. The method of claim 9, further comprising determining, by the one or more processors, the second unique address from the second identifier.
12. The method of claim 11, wherein the determination of the second unique address from the second identifier is based on a predetermined algorithm.
13. The method of claim 12, wherein the predetermined algorithm uses as an input, in addition to the second unique network address, a separate, fixed identifier associated with the paging device.
14. The method of claim 9, further comprising, responsive to reception of a corresponding communication from the wireless network, generating a sensory stimulus to page the patron, wherein the sensory stimulus is generated by a sensory interface device associated with the paging device.
15. The method of claim 14, wherein the sensory interface device comprises one or more of a light, an electronic display, or a speaker.
The claims below are in addition to those above.
