PURPOSE: A printed RFID(Radio Frequency ID) tag using a TTF(Tags-Talk-First) protocol is provided to offer reliable access to EAS(Electronic Article Surveillance), HF(High Frequency), UHF(Ultra High Frequency), and RFID systems, which read a plurality of tags and use TTF anti-collision schemes. CONSTITUTION: A memory includes at least one printed layer for providing a customizable ID. A circuit provides a bit string from the customizable ID included in a memory unit following a silence period. A clock extractor(504) generates a logic clock for a sequencer(506). A memory array(508) provides serial data output to a data encoder(510) according to access of signals, which are generated from the sequencer. Modulation control is generated from the data encoder. The modulation control is provided to a data modulator(512) for output to a reader.
