Problems solved by technology

However, this kind of virtual random number generator circuit is quite complicated in the design of electronic tags, resulting in a very high cost, so many expected applications, such as EAS and / or RFID systems, cannot be realized due to the huge cost

Abstract

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 are disclosed. In one embodiment, a 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, for example.

Description

technical field [0001] The present invention relates to electronic article surveillance (EAS), high frequency (High frequency, HF), ultrahigh frequency (Ultrahigh frequency, UHF), radio frequency (Radiofrequency, RF) and / or radio frequency identification (RFID) Electronic tags and devices. More particularly, embodiments of the present invention relate to EAS, HF, UHF, RF and / or RFID structures and methods of fabrication thereof. Background technique [0002] Typically, a low-cost RFID system includes an Interrogator or Reader, and an Electronic label or Tag. The radio frequency identification system can be widely used in retail, supply chain management, logistics, library management, and baggage claim systems, etc. Other new applications include vehicle toll tracking and / or management. Compared with common bar codes and magnetic media systems, the advantage of RFID systems is that multiple electronic tags can be read at the same time. This ability to read multiple electr...
