A system includes a processor and a memory coupled to the processor. The memory stores a database including a set of previous transactions and a set of business rules and instructions that, upon execution, cause the processor to receive a check image from a remote device, identify check information of the check image, and extract the check information from the check image. The instructions cause the processor to apply the set of business rules to the check information based on the remote device and validate the check information. The validation includes comparing the check information to the set of previous transactions, in response to the comparison identifying a duplicate transaction, determining the check image is fraudulent, and, in response to determining the check image is fraudulent, flagging the check image. The instructions cause the processor to transmit the check image and check information to the database for storage.

A method and system for authenticating an item includes providing the item including a polymer substrate comprising a polymer material and a doping material, the polymer material and the doping material configured to transmit radiation laterally through the polymer substrate, and the doping material capable of scattering radiation and absorbing radiation of at least one specific wavelength to generate a spectral signature in a spectral band of wavelengths of the transmitted radiation, irradiating the item with incident radiation characterized by a spectral band of wavelengths spanning a band of wavelengths including the at least one specific wavelength absorbed and scattered by the doping material, detecting the spectral signature after the radiation is transmitted laterally through the polymer substrate, and determining a code associated with the spectral signature.

A method for providing scratch-off lottery tickets for sale remote from a POS location in a retail establishment includes configuring the tickets with a game play area having play characters covered by a scratch-off coating. A print characteristic is provided in the game play area that is optically scannable but not reproducible when photocopying the game play area. In a database, identification of the printed characteristic is linked to a computer file associated with the lottery ticket at a central lottery computer. An optically scannable random identifier is also provided in the game play area and is linked to the computer file. Upon presentation of the lottery ticket for purchase, the ticket or a scanned image of the ticket is analyzed to verify that the print characteristic is present in the game play area. The scanned image of the ticket is analyzed to verify that the random identifier assigned to the lottery ticket is present in the game play area of the scanned image.
