A method for determining whether a candidate barcode is genuine involves acquiring an image of an original barcode; determining, from the image of the original barcode, a deviation of a continuous edge of the original barcode from a nominal shape; encoding the deviation as signature data for the original barcode; storing the signature data for the original barcode on a storage device; acquiring an image of the candidate barcode; determining, from the image of the candidate barcode, a deviation of a continuous edge of the candidate barcode from the nominal shape; retrieving the signature data for the original barcode from the storage device; comparing the signature data for the original barcode with the signature data for the candidate barcode; and making a determination that the candidate barcode is genuine or not genuine based on a result of the comparison.

Managing user devices associated with a digital wallet account comprises associating, using one or more computing devices, one or more user computing devices with a digital wallet account of a user, each of the associated one or more user computing devices being activated to conduct financial transactions with a merchant utilizing the digital wallet account; presenting the associated user computing devices in a list of associated user computing devices; receiving a request to deactivate a particular user computing device from the list of associated user computing devices; deactivating the particular user computing device, the deactivation being sufficient to prevent the user computing device from conducting transactions with a merchant utilizing the digital wallet account; and presenting a deactivated status of the particular user computing device.

The present invention is directed towards an electronic ticket suitable for providing entry to an event. The electronic ticket is capable of being stored, in electronic format, on a mobile user device. The electronic ticket comprises a dynamic entry code for the event such that the dynamic entry code is transitionable from an inoperable state to a functional state, whereby entry to the event is only possible when the dynamic entry code has been transitioned to the functional state. The dynamic entry code is a visual code which is non-readable by humans and is stored in a memory of the mobile user device, such that the inoperable state of the dynamic entry code prohibits the visual code from being displayed by the mobile user device and the functional state of the dynamic entry code permits the visual code to be displayed by the mobile user. The advantage of providing the dynamic entry code is that the electronic ticket can hide the entry code until close to the event start time so that a ticket tout will find it difficult to sell the ticket on as a purchaser would have less confidence in buying a ticket which does not display the entry code required for admission. Moreover, a ticket fraudster cannot duplicate the ticket.

A computer-implemented system and process of producing a metric quality grade profile for use during inspection of DPM symbol marked on parts may include storing average metrics measured in a controlled environment for a golden sample. Measurements of the DPM symbol of the golden sample may be performed. Measurements of the metrics of the golden sample in an uncontrolled environment may be performed. Average metrics from the uncontrolled environment may be calculated. The averaged metrics from the controlled and uncontrolled environment may be compared. The user may be enabled to set an acceptable grade for the individual metrics. The acceptable grades for the individual metrics as a profile of the DPM symbol in memory.

A printing system and method print different colors onto a target object to form a machine-readable data representation having a symbol contrast of at least 40%. The printing system and method direct print heads to print the different colors by printing a base layer of a first color of the different colors on the target object and printing an upper layer of a different, second color of the different colors on top of the base layer of the first color, or by printing print the machine-readable data representation as an interdigitated data representation by printing the different colors onto the target object so that none of the different colors is printed on top of another color of the different colors.

Disclosed is a method for access authentication. The method includes: receiving profile information of a visitor through a server, and generating a visitor code and transmitting the same to a visitor terminal, and generating a random code based on a valid visitor code, and receiving a decoding result based on decoding the random code and the visitor code by the visit terminal, and predetermining an access authority for the visitor for a predetermined time as the decoding result is successfully matched.

A device and method for imprinting a data carrier including introducing the data carrier into a printer; moving the data carrier relative to a printing head to imprint an area of the data carrier using a first ink; moving the data carrier relative to a curing station in a first direction after the data carrier has been imprinted; drying the area of the data carrier in the curing station; moving the data carrier relative to the printing head in a second direction opposite to the first direction and imprinting the area of the data carrier using a second ink, where the imprint from using the second ink is different from the imprint from using the first ink.

The combination of an EPOS terminal and a security system. The terminal has a housing with a reader for identifying information on a user card. The housing has an external surface defining an original outer configuration. The security system has at least one component configured to be fixed to the housing. The at least one component substantially effectively alters a contour of the original outer configuration of the external surface so as to block placement of a skin, with a skimming component and at least nominally matched in shape to at least a portion of the original outer configuration of the external surface, conformingly over the external surface of the housing.
