A dynamic transaction card that is manufactured using conductive plastic jumpers that will dissolve when in contact with a solvent used to tamper with the dynamic transaction card. Internal components of a dynamic transaction card may be manufactured using a synthetic or semi-synthetic organic material, such as, for example, plastics. These materials may be conductive to provide functionality to a dynamic transaction card, such as a connection between an integrated circuit and other card components such that when the materials dissolve, the connections are broken and the dynamic transaction card may be inactive due to the loss of various connections.

The invention concerns a RFID label for marking containers or equipment, preferably in a laboratory environment and including in particular cylindrical bottles, vials, syringes, etc., by adhering the RFID layer to a surface thereof. The RFID label has a flat flexible support material base (11), at least one RFID microelectronic device (5c) included in the flat support material base (11), and at least one antenna (5a,5b) connected with the at least one RFID microelectronic device (5c) and included in the flat support material base (11). The flat support material base (11) has a number of predefined cuts (8) distributed about its outer periphery and/or the at least one RFID microelectronic device (5c) includes a tamper detection function and a conductive loop (5d) connected with tamper detection function terminals of the RFID microelectronic device (5c) is included in the flat support material base (11).

Systems and methods for providing fraud prevention inserts in a chip pocket of a card are provided. A chip fraud prevention system includes a device including a chip and one or more fraud prevention inserts. The chip, and the fraud prevention inserts, may be at least partially encompassed in a chip pocket.

A radio frequency identification (RFID) tag with a configurable anti-tamper structure includes an RFID chip electrically connected to a configurable anti-tamper structure. The configurable anti-tamper structure includes a plurality of conductive segments substantially oriented in a ladder configuration. At least some of the plurality of conductive segments are cut to leave a single conductive path in accordance to the desired tamper detection application, and the RFID tag is attached with the anti-tamper structure placed across a break point to be monitored for tampering. When tampering occurs, the conductive path is broken and the RFID chip changes the data sent in response to interrogation by an RFID reader.

A system for verifying the authenticity of physical goods uses an NFC tag embedded in the product. An NFC reader positioned within range of the tag reads a unique identification number from the tag. The unique identification number may be used to generate an authentication code. During production, the manufacturer generates a blockchain record as a function of the authentication code. The blockchain record includes at least one additional identifier corresponding to the manufacturer. A consumer uses a mobile device to read the NFC tag and obtains the authentication code as a function of the unique identification number. Having the authentication code, the mobile device accesses the record in the blockchain and obtains the identifier corresponding to the manufacturer. Based upon scanning the NFC tag, the consumer is thereby able to obtain an identifier of the manufacturer to ensure authenticity of the product being purchased.

A Radio Frequency Identification (RFID) tag is disclosed. The RFID tag includes an antenna port to receive an input AC signal and a hybrid limiter including a clamping device configured to limit a voltage of the input AC signal to a preconfigured limit. The hybrid limiter is configured to provide a stable ground reference for the clamping device.

An anti-tamper device combining a RFID component and an article surveillance or security component with a visual indicator. The article surveillance or security component is operatively coupled to a display so that an interruption of the RFID component is visibly indicated by the display. The visual indicator moves between a first state indicating a lack of tampering, and a second state indicating tampering without the need for a battery or external power source.

A technique for tamper protection of incoming data signal to an electronic device is disclosed. An intentional interference signal is generated and modulated onto the incoming data signal as one composite input signal, to prevent unauthorized acquisition of valid data from the incoming data signal. The magnitude of the interference signal is adjusted to correspond to the magnitude of the incoming data signal, thereby preventing an attacker from properly differentiating the two different signals and/or decoding the valid data from the composite input signal. Once the composite input signal is safely received within the device, the interference signal can be filtered out in either analog mode or digital mode.

Systems and methods for tracking a smart container are provided. The methods use sensors of the smart container to detect tampering with the smart container after the container leaves a sender and before the container arrives at a receiver. In particular, the sensors detect when the smart container has been opened by someone other than the receiver (i.e., tampered with) and write the detection of tampering (e.g., the sensor measurement) to a blockchain. Delivery agents use scanners to write their possession or agency over the smart container to the blockchain. Accordingly, the agency of the smart container can be determined if tampering occurs.

A radio frequency identification (RFID) tag or transponder that outputs a first signal when a product or product package is sealed. During one particular use, unsealing the product or product package disables the RFID tag, such that no active second signal is output (i.e., the second signal is a passive second signal). In another particular use, unsealing the product or product package removes one or more resonators of a multiresonator such that the second signal is an active second signal that is different from the first signal. The RFID tag need not be visible to identify whether the product or product package is in a sealed state or an unsealed state.
