Abstract

A method and system for effecting bi-directional IR data communication between a plurality N of readers (21, 22, 23) and a plurality M of portable objects each having associated therewith a respective object transceiver (24, 25, 26, 27) which is initially dormant and has embedded therein a respective object ID uniquely identifying the object. Each reader transmits to an object transceiver a preamble containing the object ID for awaking the object transceiver from its initially dormant state, and a Reader Control Message (RCM) including a header; a respective reader ID so as to allow the reader to be addressed when required followed by up to K object IDs (K < M) each in respect of one of the object transceivers and each being followed by a respective command for controlling the respective object transceiver. Up to K data slots are allocated each for allowing communication of a data message between the respective reader and one of the object transceivers, and each of the M object transceivers may randomly select of one of R allocation slots for transmitting limited capacity data therein to the respective reader.
