Systems, methods, and apparatuses for tracking and monitoring a transaction card are provided. A method includes receiving a control parameter indicative of normal operation of a transaction card; acquiring operational data regarding operation and usage of the transaction card; comparing the operational data to the control parameter; responsive to the comparison, determining one of normal operation and non-normal operation of the transaction card; and, causing at least one response based on the determination, the at least one response structured to notify a user associated with the transaction card of the determination.

Trustable delivery of a product uses a package with a printed label having a unique product ID, an RFID marker applied to the product that contains the ID, and a smart chip inside the product that contains the ID and a digital key. The ID from the RFID marker is compared to the label for initial validation of the package. The smart chip is further interrogated to generate an encoded value of the ID, such as a hash value, using the digital key. The hash value is then used to authenticate the ID, thereby verifying that the product as delivered is the original, untampered product. The product ID and the hash value are recorded in a blockchain ledger associated with the product. In this manner, the packaged product can be validated by any party in the delivery chain, e.g., manufacturer, seller, distributor, delivery service, and final recipient.

RFID tags capable of transitioning between a private state and one or more public states are provided. In the private state, tags may participate in an inventory round without restriction. In a public state, tags may be prevented from participating in an inventory round, allowed to participate without providing actual identifying information, or allowed to participate providing an alternate identifier. Whether and how the tag responds in a public state may depend on certain conditions including if one or more of the tag's flags are asserted or deasserted. A reader may select a public tag for inventorying by verifying itself, and the tag then asserting or deasserting one or more of its flags accordingly. The asserted or deasserted flag(s) may be used to determine whether and how a tag in a public state participates in an inventory round.

In embodiments of the present invention improved capabilities are described for a system and method for a wireless computing device monitoring data stored in a data memory store by a monitoring function executed by a set of instructions stored on the wireless computing device, the wireless computing device comprising an antenna, an analog block for receiving and transmitting an RF signal through the antenna wherein energy from the received RF signal provides power to the wireless computing device, and a data processing and controller block adapted to store the set of instructions.

A system for protecting personal data contained on an RFID-enabled device, suitable for use with an RFID system including an RFID reader configured to extract information from an RFID chip associated with the RFID-enabled device, includes a personal data protection system including a personal data protection device configured to prevent reading of the RFID chip associated with an RFID-enabled personal item.

Aspects of the invention relate to components for constructing a payment instrument that includes enhanced electronic features. Apparatus may include an all-inclusive smart card that securely stores sensitive data. Such sensitive data may include credit card, driver's license or passport information. The smart card may generate disposable card numbers for online or offline onetime transactions.

The invention relates to a data tag having a memory (32) for storing a data set and a contactless interface (26, 28) for supplying data from the memory to a remote reader (20). The contactless interface is configured to be interrogated through an electromagnetic field (22) from the reader. The data tag further comprises a plurality of sensors (50) which are spatially separated and which are configured to sense the interrogating electromagnetic field, and a processing device (54) configured to receive outputs from the sensors representative of the interrogating field and to: enable supply of data from the data set through the contactless interface if variability of the sensed outputs is sufficient to indicate that the reader and the data tag are in close proximity; and to disable supply of data from the data set through the contactless interface if variability of the sensed outputs is not sufficient to indicate that the reader and the data tag are in close proximity.

Example embodiments of systems and methods for data transmission system between transmitting and receiving devices are provided. In an embodiment, each of the transmitting and receiving devices can contain a master key. The transmitting device can generate a diversified key using the master key, protect a counter value and encrypt data prior to transmitting to the receiving device, which can generate the diversified key based on the master key and can decrypt the data and validate the protected counter value using the diversified key.

Systems and methods for overmolding a card are provided. A chip fraud prevention system include a device including a chip and a substrate. The chip may be at least partially encompassed in a chip pocket, and the substrate may be at least partially encompassed by the overmold.

A method for operating a first near field communication, NFC, device, wherein the NFC device comprises an NFC interface and a memory, the method comprising: i) receiving a request for a service from a second NFC device at the NFC interface, ii) allocating a first information from a first memory unit of the memory that is configured to take part in providing the service, iii) allocating a second information from a second memory unit that is not configured to take part in providing the service, and transferring the second information from the second memory unit to the first memory unit, hereby iv) transferring at least a part of the first information and/or at least a part of the second information virtually beyond the first memory unit, v) combining the first information and the second information into a message, and vi) providing the message to the second NFC device as a response to the request.
