The system may include a processor configured to perform operations and/or steps comprising receiving a wireless signal from a transaction device, wherein the wireless signal carries emulated track data for payment of a transaction; reading the emulated track data from the wireless signal; generating a transaction payload, wherein the transaction payload contains transaction account data and a dynamically generated digital signature value from the emulated track data of the wireless signal; transmitting the transaction payload to an authorization network server; receiving an authorization instruction from the authorization network server for handling payment of the transaction; and processing the payment of the transaction in accordance with the authorization instruction.

A control system for a surgical instrument. The control system comprises an RFID scanner and a control circuit coupled to the RFID scanner. The control circuit is configured to receive data from RFID tags associated with devices, determine whether the devices are compatible based on a comparison of the received data, and provide an alert that the devices are incompatible or a suggestion to replace one of the devices with a replacement compatible device.

A non-contact type information processing device structured to communicate with a medium in a non-contact manner may include a first circuit part having a first antenna, and the first circuit part may be configured to communicate with the medium at a first resonance frequency by electromagnetic induction. The non-contact type information processing device may further include a second circuit part having a second resonance frequency which is separated from the first resonance frequency, and the second circuit part may include a second antenna and a light emitting element which is operated by electric power obtained by an induced current that is received by the second antenna.

A method and system for obtaining wire information, includes a RFID tag, a RFID reader, and a data center. The RFID tact obtains the sensing information of the wire and transmits the sensing information and identification information of the RFID tag. The RFID reader transmits high-frequency electromagnetic waves to trigger the RFID tact and transmits and receives sensing information and identification information sent by the RFID tag. The data center is communicatively connected with the RFID reader and determines the type of the received sensing information based on the received sensing information and identification information for data analysis.

A payment card (e.g., credit and/or debit card) or other device (e.g., mobile telephone) is provided with a magnetic emulator operable to communicate data to a magnetic stripe read-head. Gift cards may be inputted by a user into such a payment card or other device such that a user can combine gift cards. Similarly, a user be provided with a global payment account that can be utilized in multiple countries that have different standards for formatting data. A user may be provided with a default country (e.g., United States) but may have a way to select that the user is in a different country (e.g., Japan). Accordingly, a user may select that a Japanese data structure be transmitted through a magnetic stripe reader when the user is in Japan.

A magnetic sensor array device is described that is constructed with multiple single sensor die, diced out of a wafer as a group and packaged in a wafer level package (WLP). The device comprises an array of multi-axis magnetic sensors that can measure the multi-dimensional magnetic field of an arbitrary sized two-dimensional region with high spatial resolution, reduced sensing distance, higher measurement throughput, tolerance to motion, improved temperature measurement, and improved yield when placed on a circuit card comprises part of an authentication system including a physical unclonable function (“PUF”), a substrate, a plurality of magnetized particles randomly dispersed in the substrate, and a PUF reader constructed using one or more of the magnetic sensor array devices wherein the PUF reader measures the magnetic field at multiple locations in close proximity to the magnetized particles. The measured magnetic field data may be compared to previously enrolled data to assess authenticity.

A portable device comprises a magnetometer for detecting a magnetic field. When the portable device is at or near a portal, the portable device may detect data from the portal, such as beacon data or a connection message. Responsive to the data from the portal, the portable device operates the magnetometer to detect and characterize a magnetic field generated by the portal, such as by characterizing the magnitude, polarity, and direction of the magnetic field. The portable device generates magnetometer data to indicate the magnetic field strength detected by the magnetometer. The magnetometer data is then transmitted to the portal, along with a device identifier. The portal compares the received magnetometer data to expected magnetic field data to determine presence of the portable device at the portal. The portable device is associated with an account, providing information about entry of a user of that account entering the portal.

Methods and systems are described herein for locally deactivating transaction cards to prevent offline transactions. A processor associated with the transaction card may be used in the process to locally deactivate transaction cards. The processor on the transaction card may receive a signal from a transaction terminal requesting a connection with the transaction card and may establish a connection with the transaction terminal. The processor may an indication to deactivate the transaction card and in response to receiving the indication apply an electric current to a stripe deactivating element that deactivates at least a portion of one or more tracks of a stripe on the transaction card and cause, via a built-in circuit, a predetermined increase in the electric current to the processor that causes a pathway that enables power distribution to the processor to be destroyed.

An embedded trace capacitive signet is described. The embedded trace capacitive signet provides for authentication and validation through interaction with a touch screen of a computing device such as a smart phone. The embedded trace capacitive signet has a substrate such as a card, a plurality of conductive circle points affixed to the substrate, a user conductive area that allows a user to provide capacitance to the conductive circle points, and thin traces connecting each circle point to the user conductive area. Placing the circle points in different locations produces unique cards that can be detected by a touch screen of a computing device to initiate a software based application.
