<p><P>PROBLEM TO BE SOLVED: To provide a method, algorithm, architecture, circuits, and/or systems for EAS, HF, UHF, and RFID designs suitable for multi-tag read applications using TTF anti-collision schemes. <P>SOLUTION: A tag tag for wirelessly communicating with a reader can include: (i) a memory portion with an identifier, the memory having 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 can include pre-programmed memory bits (e.g., bits the value of which is programmed by printing), or alternatively, memory bits formed by conventional photolithography, but having connections made using printing technology to form the identifier. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
