A system and computer-implemented method for detecting and addressing billing fraud by an asserted provider of a good or service based on location data associated with card-based financial transactions by an asserted recipient and collected, stored, analyzed, and acted on by a payment card network to determine and respond to a likelihood of fraud. A computer stores locations of the recipient based on uses of a payment card over a time period, and determines a location of the provider based on location data associated with a card reader at a particular time at which the good or service was allegedly provided. The computer compares the two locations for the particular time and generates a fraud score based on a likelihood that the recipient was physically capable of being at the provider location at the particular time, and based on the score, may notify the recipient and decline the payment request.

According to one or more embodiments, a wireless tag reader includes a first shield member, a second shield member, an antenna, and a reader. The first and second shield members face each other across a reading area through which a wireless tag can pass. Each of the first and second shield members has a reflective surface that reflects a radio wave incident thereon toward the reading area. The antenna is between the reading area and the reflective surface of one of the first and second shield members. The antenna radiates and receives radio waves to communicate with the wireless tag. The reader reads data stored in the wireless tag based on radio waves received from the wireless tag by the antenna.

An electronic book using electromagnetic energy to detect page numbers includes a book and a base, the book includes a plurality of book pages, each of the book pages is respectively provided with an electromagnetic energy changing member, and the base is provided with at least one antenna coil and at least one control circuit. The electromagnetic energy changing member of each of the book pages is correspondingly disposed adjacent to a position of the antenna coil, and a magnetic flux generated by the antenna coil is transmitted to the electromagnetic energy changing members. The electromagnetic energy changing members generate magnetic variable fluxes to be received by the antenna coil for generating a page number prompt output command by conversion to control generation of a prompt function of the book page correspondingly disposed adjacent to the position of the antenna coil.

A point-of-sale (POS) device includes a processor, a battery, a transaction object reader, a printer with a printer controller, and optionally a temperature sensor. The processor determines a present power discharge capability rate of the battery, optionally based on a temperature measured by the temperature sensor. The processor also calculates a first estimated power draw rate based on a first setting value for at least one of the components of the POS device, such as the printer. If the first estimated power draw rate is dangerously close to the present power discharge capability rate of the battery, a second estimated power draw rate is calculated based on a second setting value for the one or more components. If the second estimated power draw rate is no longer dangerously close to the present power discharge capability rate of the battery, the components are set to the second settings value.

A non-transitory computer-readable medium stores instructions causing a processor to generate a menu displaying representations of a plurality of cards, the cards having associated card data; receive, from a user input device, a selection corresponding to a selected one of the cards; update the menu to display a representation of the selection; and authorize transmission of the card data associated with the selected card to complete a transaction.

A method includes receiving from a first detection system, a plurality of identity tokens, the plurality of identity tokens including different types of identity tokens, the first detection system having a plurality of different types of detection instruments, receiving from a second detection system, a number of identity tokens, the second detection system having a plurality of different types of detection instruments, using information from the first detection system and the second detection system, creating correlation information that correlates different types of identity tokens, using information from the first detection system and the second detection system, determining path likelihood for a plurality of moving objects passing through the first detection system and the second detection system, and updating the correlation information using the path likelihood for the plurality of moving objects.

A point of sale (POS) device includes tamper detection circuitry in which one or more flexible members that each include multiple side-by-side conductive traces connect two circuit boards, optionally so that one circuit board must remain very close to the other if the device remains in a secure un-tampered-with state. Severance of a trace of the flexible member, or disconnection of the flexible member from either circuit board, may result in unexpected voltage sensor readings indicative of a tamper attempt.

A reader device for reading information stored on a magnetic strip containing a plurality of polarized magnets, each providing a magnetic flux, said reader device including: a magnetoresistive sensor including a plurality of magnetoresistive elements and configured for reading the information stored on the magnetic strip and outputting a read signal; a processing module configured for decoding the read signal and extracting binary data; wherein the read signal includes amplitude information of the magnetic flux; and wherein the processing module is further configured for decoding the read signal using the amplitude information of the read signal is described. Further, an amplitude decoding method for decoding the read signal outputted by the reader device is described.

Currency processing systems, coin processing machines, and methods of imaging coins are presented herein. A currency processing system is disclosed which includes a housing with a coin input area for receiving coins and coin receptacles for stowing processed coins. A disk-type coin processing unit is coupled to the coin input area and coin receptacles. The disk-type coin processing unit includes a rotatable disk for imparting motion to the coins, and a sorting head having a lower surface adjacent the rotatable disk. The lower surface forms various shaped regions for guiding the coins, under the motion imparted by the rotatable disk, to exit channels through which the coins are discharged to the coin receptacles. A linear array of sensors is mounted to the sorting head and/or the rotatable disk. The sensors examine each coin on the rotatable disk and output a signal indicative of coin image information for processing the coin.
