There are provided systems and methods for a physical card having one or more location detection modules for location-specific card reading. A physical payment card may include one or more components to limit card reading of card data stored to the card using a location detection chip. The location detection chip may receive power from a source when inserted to a card reader, and may then determine a location of the card, such as a coordinate location of the card or nearby detected device. The location detection chip may determine if this location or device matches authorized locations stored in a memory of the card. If it does, power may be provided to a card chip of the card. The card chip of the card reads card data from a memory of the card and may then output the card data to the card reader.

A method, system and apparatus are provided for estimating characteristics of a wireless communication channel between at least two passive radio frequency (RF) nodes. Backscatter channel state information (BCSI) is measured during communication between the at least two passive RF nodes using the wireless communication channel. An RF node aggregates the measured BCSI and the aggregated BSCI is analyzed to detect at least one activity of a plurality of activities.

An electronic device for monitoring. The electronic device includes a functional module arranged to provide an active function, a communication module arranged to communicate with an external communication device, and an energy harvesting module arranged to transform a source energy from an external source to electrical energy for energising both the communication module and the functional module.

An RFID inlay includes an RFID module and an antenna. The RFID module includes an RFIC and an antenna sharing circuit provided between the RFIC and the antenna. The RFIC includes a power receiving terminal to which power induced upon receipt of an electromagnetic wave for power reception is input and a transmitting terminal from which a transmission signal for RFID is output. Moreover, the antenna receives the electromagnetic wave for power reception and generates an electromagnetic wave for RFID.

A secure smart card is described. The smart card can include a processor, a memory and a transceiver. The smart card can communicate with various terminals and store a digital signature and other information on the card. Another terminal can validate the information stored on the smart card using the digital signature. In certain embodiments, the terminal can also validate the information by using a blockchain. The advanced design of the smart card obviates the need for a network connection.

In embodiments of the present disclosure improved capabilities are described for a tag operating system configured to manage asset data exchanged between an RF reader and one or more asset RF tags, and an IoT connector core integrated with the tag operating system, where the IoT connector core transfers asset data collected via the RF reader from the one or more asset RF tags and delivers the asset data to an IoT system of a cloud platform over a data exchange protocol, and where the asset data was generated at least in part based on an endpoint intelligence function stored on the one or more asset RF tags.

A modular transaction card assembly includes a card frame having the traditional dimensions of a credit card, and a transaction card that is smaller than a traditional card and that fits into a receptacle of the card frame. Each of the card frame and the transaction card may be capable of performing contactless data transactions individually. The combined assembly of the card frame with the transaction card secured in the receptacle is also capable of performing contact data transactions, and in some instances, with an identifier that is distinct from the card frame or the transaction card alone. The card frame may include a processor enabling it to perform data encryption and authentication of the smaller transaction card.

A trickle-charged RFID device includes a main antenna receiving wireless interrogator signals from one or more RFID readers, a power harvester connected with the main antenna to obtain power from the wireless interrogator signals, and an intermediate storage device connected to the power harvester to collect trickle flows of unused power harvested from wireless interrogator signals received by the RFID device that lack an inquiry for the device. The RFID device further includes a primary storage device, into which the intermediate storage device discharges its collection of trickle flows of unused power when the collection reaches a predetermined threshold level, which recharges power lost from the main storage device. The intermediate storage device can include one or more capacitors including super-capacitors, and the main storage device can include a rechargeable battery, such that the effective life of the main storage device is extended from the collected trickle flows.
