When in alert mode, the transceiver broadcasts position and identifier information of the UAS to alert neighboring aircraft to its presence. Intelligent transmission strategies regulate the power level or rate of alert-mode transmissions to reduce spectrum congestion due to high UAS density. Alert-mode transmissions continue until the underlying conditions change and inert mode is resumed. |

System and architecture for electronic fraud detection
Embodiments of an electronic fraud analysis platform system are disclosed which may be used to analyze tax returns for potential fraud. Analysis of tax return data using the tax return analysis platform computing systems and methods discussed herein may provide insight into whether a tax return may be fraudulent based on, for example, an initial screening component configured to filter tax returns which appear fraudulent due to missing or inaccurate information provided with the return; a device activity analysis component configured to identify whether a device used to submit a tax return or to provide further authentication information needed to complete processing of the return may have been used in other fraudulent activities; and a knowledge-based authentication component configured to identify potential fraudsters using dynamically generated questions for which fraudsters typically do not know the answers. |

Non-intrusive geo-location determination associated with transaction authorization
Embodiments of the invention are directed to systems, methods, and computer program products for non-intrusive geo-location determination associated with transaction authorization. The invention enables one or more transactions initiated by a user to be authenticated and/or validated based on, at least in part, determined locations of the user relative to the locations of the one or more transactions. The user location is determined by transmitting one or more queries to a user device. The system determines the validity of the one or more transactions based on at least comparing the transaction location to the user location, before enabling further processing of the one or more transactions. The present invention is advantageous since it enables authentication/authorization of one or more transactions associated with the user by utilizing the user location, while precluding any inadvertent privacy concerns. |

Automated fraud detection
Transaction information for a card transaction is automatically and selectively rendered to a screen of a display presented to a user. The user can edit zero or more operators and selected values provided in the screen and save any such edits. When saved, the transaction information and any edited operators and/or selected values are used to generate a rule for a fraud detection system for immediate application. Subsequent card transactions are evaluated in view of the generated rule to automatically detect any fraudulent transactions present in the card transactions. |

System and method for a mobile wallet
A computer-implemented method for receipt management includes receiving, using a mobile wallet stored on a mobile device of a user, receipts that include a record of transactions between the user and one or more merchants, the transactions being performed using the mobile wallet account of the user. The method includes receiving receipts for transactions that were not performed using the mobile wallet account of the user, the receipts being received from a user e-mail address, the receipts for non-mobile wallet transactions being received by the mobile wallet of the user. The method includes aggregating the mobile wallet receipts with the receipts of non-mobile wallet transactions and retrieving and displaying one or more of the mobile wallet receipts and the receipts of non-mobile wallet transactions. |

System, method, and apparatus for a dynamic transaction card
A dynamic transaction card with a display for providing barcodes is described. The barcodes can be generated by driving individual light emitting diodes (LEDs) of the display at frequencies of greater than 50 Hz. Due to the high frequency, the barcode can be readable by a barcode scanner, while remaining invisible to the human eye. The barcode can also be generated by driving a first set of LEDs at a different frequency and/or time interval than a second set of LEDs. Light waves from the first set of LEDs can constructively interfere with light waves from the second set of LEDs to create spatial voids readable by the barcode scanner. |
