An updateable electronic-ink based display label device for attachment to an object to be tracked. The device includes (i) an addressable display assembly including a layer of electronic ink, (ii) an antenna structure, (iii) an interface module, and (iv) a signal transceiver module. The signal transceiver module is responsive to electromagnetic data signals received from a remote communication module, and the addressable display assembly is responsive to output signals generated by the interface module, to display the determined graphical indicia. The antenna structure, the interface module, the signal transceiver module, and the antenna structure are arranged and stacked together to form the updateable electronic-ink based display label device.
