A diaper wetness detection system includes a diaper, a wetness sensor, an RFID unit, and a transceiver unit. The RFID unit is a battery-less device that receives an interrogation signal transmitted by the transceiver unit. The RFID unit or the transceiver unit are configured to determine if a measurable characteristic, as sensed by the wetness sensor, indicates if the diaper is wet. The measurable characteristic can be a voltage or current indicative of a resistance, capacitance, or impedance at an area sensed by the wetness sensor. The value of the measurable characteristic is different when the diaper is wet versus dry. Comparing the measurable characteristic value to a threshold value or to one or more previously sensed measurable characteristic values enables a determination to be made as to whether or not the diaper is wet. The RFID unit can be detachably coupled to the diaper for simple attachment and removal.

A security device includes a memory device including instructions. At least one processor is configured for executing the instructions to: receive images of at least one physical object from at least one camera connected to the at least one processor, receive an indication from at least one security tether indicating movement of the at least one physical object, and provide an alert based on the indication of movement of the at least one physical object.

Radio frequency identification (RFID) enabled readers and systems and methods for filtering cross reads of RFID tags and use thereof. The systems and methods may be configured to operate with mobile and/or fixed RFID readers. The systems and methods may provide for claim based filtering of cross reads based upon adjusting operating powers of RFID readers and/or antenna. The systems and methods may also be configured to apply weights to claims thereby providing efficient and/or accurate filtering of cross reads. The systems and methods may also provide for a database that may also be presented to a user to illustrate locations of inventory at any point in time or over a period of time, or to facilitate the ability of a user to physically locate inventory to be acted upon.

A goods purchase analysis assist system is provided that can not only prevent checkouts from being crowded, but also perform settlement at timing convenient for the customer. A goods purchase analysis assist system includes a management server that communicates with a terminal of a customer, and manages purchase of goods in a store by the customer, wherein gates for managing entry and exit of the customer are installed in the store, gates for exit among the gates are configured as a first exit gate through which the customer having performed shopping passes, and a second exit gate through which the customer having not performed shopping passes, and the management server manages entry and exit of the customer passing through the gate.

The present disclosure relates to the field of product authentication and counterfeit detection and discloses a system and method to detect counterfeit products. The system (100) comprises a first scanner (102), an application (132) loaded in a user device (114) and a server (110). The first scanner (102) scans images of visual codes printed on products manufactured and packaged on a production line and assigns product details to the visual codes. The application (132) facilitates a user to scan said visual codes and redirects the user to an encoded URL to view the product details. The application (132) captures and transmits a browser ID and location data to the server (110) and allows users to provide inputs to a pre-determined set of questions. The server (110) derives scanning indices from the received browser ID and location data and identifies counterfeit products based on said scanning indices and inputs.

A shopping cart scanning device, including a main body, a scanner disposed on at least a portion of the main body to scan a machine-readable code of at least one item, a scale movably disposed within at least a portion of the main body to receive the at least one item thereon, such that a weight of the at least one item is determined, a display unit disposed on at least a portion of the main body to display at least one of a price of the at least one item in response to the scanner scanning the at least one item and the weight of the at least one item in response to the scale receiving the at least one item thereon, and a cart clip disposed on at least a portion of the main body to removably connect the main body to a shopping cart.

A system for an ID card identification prevents unauthorized entry to a venue by comparing ID card data for validity and internal matching of a person to a photo on an ID card. The system includes an identification card offered by an individual seeking entry; wherein the identification card includes a photograph of the individual the card is assigned to. An electronic device having a camera thereon takes a photograph of the photograph on the identification card. The electronic device takes a picture of individual offering the identification card for access to the venue. The electronic device verifies the authenticity of the identification card. The electronic device having circuitry and software which determines a match, low match or no match between the individual in the photograph on the identification card and the photograph of the individual presenting the identification card, for entry into the venue.

The invention provides systems and methods for managing identifier labels for use in tracking one or more associated products in a supply chain.

A system having a radio-frequency-identification (RFID) tag reader and a camera to map playing cards to RFID tag values. Each card is inserted into a sleeve that has an RFID tag. During or after insertion of a card into a sleeve, the camera captures an image of the card and the RFID reader captures an RFID tag value for the sleeve. The identity of the card is then determined from the captured image and mapped to the RFID tag value. This mapping information is generated for each card-sleeve pair in a card deck and utilized to track the movement of the cards during game play. The RFID tag value of each card-sleeve pair in the card deck is captured before and after a player draws a card from the deck. The missing RFID tag values are compared to the mapping information to identify which cards where drawn by the player.

A tag reading device includes an external interface, an RFID interface, a buffer memory, and a processor. The external interface communicates with a higher-level device. The RFID interface reads tag information from an RFID tag. The buffer memory sequentially records the tag information read from the RFID tag using the RFID interface. The processor transmits the tag information recorded in order in the buffer memory to the higher-level device via the external interface, and updates a transmission start pointer indicating untransmitted tag information in the buffer memory.
