<P>PROBLEM TO BE SOLVED: To provide a method, an algorithm, architecture, a circuit, and/or a system for EAS, HF, UHF, and RFID designs suitable for multiple tag reading applications using a TTF collision prevention scheme. <P>SOLUTION: A tag for wirelessly communicating with a reader is configured to comprise: (i) a memory portion having an identifier and at least one printed layer; and (ii) a circuit for providing a bit string followed by a predetermined silent period, where the bit string is related to the identifier. The tag comprises pre-programmed memory bits (for example, bits values of which are programmed by printing), or memory bits formed by conventional photolithography, and having a connection made by using printing technology to form the identifier. <P>COPYRIGHT: (C)2012,JPO&INPIT |
