A two part dual layer transaction device comprising a computerized master unit powered by rechargeable battery, the master unit capable of connecting wirelessly to a data network and accessing at least one network server, the master unit having a length, a width, and an internal volume, and a transaction card element having a form factor acceptable for use as a debit or credit card, wherein the transaction card element may be docked or otherwise coupled to the master unit in an idle state and may be uncoupled by the user for the purpose using or cleaning the card element.

A structure for secure containment of information (SSCI) that is in the form of a laminate which includes at least two layers. The laminate is constructed to contain information such as a code, serial number, informational feature, encryption key or personal identification number (PIN). The information is located between the layer of the laminate such that the code, serial number, informational feature, encryption key, or PIN is not detectable from outside the laminate. The SSCI is configured to provide access and expose the code, serial number, informational feature, encryption key, or PIN by delaminating at least one layer, thereby indicating that tampering has occurred to the laminate. The SSCI can also function as a public key or private key for a blockchain, to provide access to a physical lock or to provide account access to claim financial value.

A device and method for displaying security information to a user is provided. The present invention may include a security device configured to display a security information on a display surface. The security information may include at least one component having two images based on a splitting of its representation that are viewable from corresponding angles of view. The images may be fused into the representation of the at least one component by a visual system of the user looking at them at a reading distance causing the eyes of the user to look at the images from the corresponding angles of view. A corresponding method for displaying security information to a user is also provided.

In some implementations, a system may receive door position information that indicates a position of a door of a room. The system may receive, in association with a read operation of an RFID reader, first tag information associated with a first RFID tag, wherein the first tag information is received via a first antenna of the RFID reader, and wherein the RFID reader is disposed within the room and a first directional range of the first antenna is directed toward the door. The system may determine, based on the first tag information being received via the first antenna, a location status of the first RFID tag according to the door position information. The system may perform, based on the location status, an action associated with indicating a location of the first RFID tag.

An RFID label includes an RFID inlay and has a waveform portion formed on at least a part of a peripheral edge.

Near Field Communication (NFC) chips or tags are securely activated where at least one validation or redemption number is assigned to the chip or tag at the time of activation. Subsequent to activation, the NFC chip or tag enables secure data access via an Ancillary Device. Validation or redemption of the NFC chip or tag is also provided for.

Systems, devices, admixtures, and methods are described including transponder devices (e.g., a palatable transponder, an edible transponder, a palatable radio frequency identification (RFID) tag, an edible RFID tag, etc.) for admixing with a food product.

The present application provides an interposer, including an interposer substrate, at least one through silicon via, a first shield layer, a first insulation layer, a first cable layout layer, and at least one first bump. The interposer substrate includes an upper surface and a lower surface; the at least one through silicon via is buried in the interposer substrate and runs through the upper surface and the lower surface; the first shield layer is disposed on the upper surface of the interposer substrate and the first shield layer has electrical conductivity; the first insulation layer is disposed at the first shield layer; the first cable layout layer is disposed at the first insulation layer and is electrically connected to the at least one through silicon via.

A portable item reporting device (200) is configured to be attached to and in substantial collocation with a portable item (100), or to be integrated into a portable item (100). The device (200) includes environmental sensors (210) to monitor item location, movement, ambient light, sounds, temperature, etc. The device (200) is configured to store usage expectation data (600) indicative of historical and/or expected item usage and environments when the item (100) is in normal use/storage associated with an authorized user (AU). The device (200) monitors current environmental conditions (104) surrounding and pertaining to the item. If the current environment (104) is inconsistent with expected conditions (600), the device (200) assesses that the item (100) is displaced (503.0), meaning either that the item (100) is in abnormal use or abnormal storage, or is under the control of an unauthorized user (UU) who is other than the authorized user (AU). Based on the assessment the device initiates a signal (372) or message (374) to an authorized user (AU) of the item (100), indicating that the item (100) usage/storage is displaced (503.0) or otherwise anomalous (503.2).
