An electronic-ink labeling system for displaying graphical indicia within the space of a physical environment. The system includes a plurality of remote activator modules installed within the space of the physical environment, and a plurality of remotely-updateable electronic-ink labels installed within the space of the physical environment. Each remote activator module sends and transmits electromagnetic signals within the space of the physical environment. Each electronic-ink label employs an addressable display assembly including a layer of electronic ink including a bi-stable non-volatile imaging material. The device includes an integrated circuit structure having a storage element for storing instructions, programs and data, and a programmed processor in electrical communication with the addressable display assembly and an antenna structure. A signal transmitting structure transmits signals from the antenna structure to the remote activator module. A signal receiving structure receives electromagnetic signals from the remote activator module, using the antenna structure. An on-board battery power structure, operably connected to the integrated circuit structure, supplies electrical power to the integrated circuit structure. Each electronic-ink label is assigned a unique encryption key so that when a common encrypted message broadcast is transmitted as an electromagnetic signal to the electronic-ink labels, only a subset of the electronic-ink labels, assigned unique encryption keys, are allowed to receive the broadcasted messages.
