A storage box state determination system according to the present invention has: a storage unit that stores an identification information management table in which tag IDs of multiple wireless tags are associated with a storage box ID of a storage box, and a state management table in which an empty state and a storing state are associated with the number of tag IDs; an information acquisition unit that acquires the tag IDs using an antenna that receives radio waves of the wireless tags of the storage box 31; a number identification unit that identifies the number of acquired tag IDs which correspond to the storage box ID; and a state identification unit that identifies, on the basis of the number of acquisition, whether the state of the storage box as indicated by the storage box ID corresponding to the tag IDs is an empty state or a storing state.

Approaches herein provide protection for an identification chip of a contactless device using a transmission blocking element. In some approaches, a contactless card may include a body having first and second main sides. An identification chip may be coupled to the first main side, and the transmission blocking element may be slidably coupled to the body. The identification chip is covered by the transmission blocking element in a first position, and uncovered by the transmission blocking element when the transmission blocking element is in a second position. The transmission blocking element may include a first section extending along the first main side of the body, and a second section extending parallel to the first section. The transmission blocking element may further include a tab coupling together the first and second sections, wherein the tab is positioned within an internal slot embedded within the body.

A passive device shield 2 used to protect a passive chip containing data embedded in a device from remote skimming at a frequency which activates the chip to send the data, the shield 2 being removable to enable authorized reading of the chip data. The shield 2 is adapted to block the frequencies which activate the chip, the shield 2 further having a transmitter 18 which sends a coupling signal at a non-blocked frequency to a receiver 20, at least one of the receiver/and transmitter 18 having means to monitor the distance between the transmitter 18 and receiver 20 and an alert means to indicate when a predetermined distance has been exceeded.

Systems and methods are disclosed for an electronic label system. An electronic label may include a reflective component configured to reflect light transmitted by a light source. The electronic label may also include a light blocking device configured. The light blocking device may prevent at least a portion of the light transmitted by the light source from reaching the reflective component when in a first configuration. The light blocking device may also allow the light transmitted by the light source to reach the reflective component when in a second configuration. The electronic label also includes a processing device configured to control operation of the light blocking device. The light blocking device further includes a power generation device configured to generate power for the light blocking device and the processing device.

An RFID tag and a method of its use are disclosed. One such RFID tag includes first, second, and third RFID inlays included on a tag housing, the first, second, and third RFID inlays each corresponding to a different rate identifier. The tag also includes a panel engaged with the housing and movable among first, second and third positions. The panel includes RFID shorting structures each positioned to electrically contact one of the first, second, and third RFID inlays such that, in any of the first, second, and third positions, only one of the first, second, and third RFID inlays remains active.

Provided is a security code including a substrate, metamaterials on the substrate, a signal modulation pattern on the metamaterials, and a capping layer covering the signal modulation pattern and the metamaterials, wherein the metamaterials include a pair of metal patterns facing each other, the signal modulation pattern covers a portion of the metal patterns, and expose remaining of the metal patterns, and the signal modulation pattern has a different material from each of the metal patterns.

An integrated circuit chip and a method for protecting the integrated circuit chip against physical and/or electrical alterations are disclosed. The chip comprises at least one semiconductor layer including semiconductor components and conductive tracks, at least one layer formed by a first type of conductive tracks extending over all or part of a surface of the chip and at least one second type of conductive track connected to at least one detection circuit configured to detect an alteration of the at least one second type of conductive track. The chip is characterized in that the at least one first type of conductive track is mixed within the at least one second type of conductive track, the material and the layout of at least one second type of conductive track being indiscernible, by an observation device, from the material and the layout of the at least one first type of conductive track.

Radio frequency identification (RFID) enabled devices are presented. In some examples, a RFID tag may be arranged on the device and the device may further include a RFID tag mode modifier which is configured to transfer the mode or state of the RFID tag from a first mode, such as an inactive mode, to a second mode, such as an active or enabled mode, or vice versa. For instance, the RFID tag mode modifier may transfer the RFID tag from an inactive mode or state to an active mode or state in which the RFID tag may be enabled for use, or vice versa. The RFID tag mode modifier may be an activation button, a contact region, or a physical device configured to prevent transmission of RFID signals. One or more methods of generating or using the devices described herein are also provided.
