Abstract: Systems and methods for identifying one or more objects hung from a display peg are described herein. The system may include a display peg comprising a first and second electrically conductive terminal. An object comprising a resistive element may be hung from the display peg such that the resistive element is in electrical communication with the terminals. A source may be configured to provide a current that flows from the first terminal through the resistive element to the second terminal. An electronic device may be configured to detect the electrical current flowing from the second terminal. The system may be configured to identify the type of object depending on the detected electrical current.

Abstract: Systems and methods for identifying one or more objects hung from a display peg are described herein. The system may include a display peg comprising a first and second electrically conductive terminal. An object comprising a resistive element having a preselected resistance may be hung from the display peg such that the resistive element is in electrical communication with the terminals. A source may be configured to provide a current that flows from the first terminal through the resistive element to the second terminal. An electronic device may be configured to detect the current flowing from the second terminal. The system may be configured to identify the type of object depending on the pre-selected resistance of the resistive element.

Abstract: An RFID antenna is fabricated according to varying current density requirements of different regions of the antenna. A method such as computer modeling is used to determine the current densities of the antenna regions. In one aspect of the invention, a conductive material is printed to a substrate at varying thickness according to current density requirements of particular antenna regions. In another aspect of the invention, materials of different conductivity are printed to the substrate according to the current density requirements. A material of higher conductivity is printed at an antenna region that requires high current density, and a material of lower conductivity is printed at antenna region that requires lower current density.

Abstract: A conductive ink composition comprising a carboxylic acid- or anhydride-functional aromatic vinyl polymer, a conductive particulate material, and/or a conductive flake material (any material with an aspect ratio of at least about 5:1) may be printed in a thickness of five microns or less to provide sufficient conductivity for RFID tag antenna and other printed conductive and semi-conductive structures. Printing the ink by flexographic or gravure printing offers advantages over other printing methods previously used.
