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 card reader includes a digital connector such as a Universal Serial Bus (USB) plug or an Apple® Lightning® plug. The digital connector includes a corresponding connector interface, which provides voltage to at least a card reader interface and an integrated circuit (IC) of the card reader. The card reader interface outputs an analog transaction information signal upon reading the card. The IC generates a digital version of the analog transaction information signal, encrypts the digital version, converts that into an analog audio signal. The audio signal can then be sent to the connector interface, which converts it into a digital signal such as a USB or Apple® Lightning® signal that is sent by the digital connector to a mobile device. Alternately, the audio signal can be sent to a microcontroller that converts the audio signal to a digital format such as USB, and then to the digital connector.

A capacitive sensing identification tag includes a substrate and a touch sensing layer disposed on one side of the substrate. The touch sensing layer includes high-sensing regions and low-sensing regions with different shapes. Both the high-sensing regions and the low-sensing regions have different stacked conductive layers and dielectric layers. A difference between the high-sensing regions and the low-sensing regions is that each of the high-sensing regions contains a dielectric layer, while each of the low-sensing regions does not. The capacitive sensing identification tag achieves an effect of sampling and identification of a touch panel by a capacitive sensing quantity that is different from a capacitive touch panel. And the capacitive sensing identification tag will not cause a difference in color or light transmittance between the high-sensing regions and the low-sensing regions, so there is no visible difference between the high-sensing regions and the low-sensing regions.

The present invention relates to a method comprising providing one or more information carrier(s) with a dielectric and/or conductive pattern and a detection device having a capacitive touch screen and inducing an interaction between the information carrier and the touch screen, wherein the interaction is based on a difference in the dielectric coefficient and/or the conductivity of the pattern and generates a touch signal and wherein the interaction is induced by relative motion between the information carrier and the touch screen. The invention further relates to a system comprising an information carrier comprising a dielectric and/or conductive pattern which encodes information and a detection device having a touch screen; the detection device is able to decode the information upon interaction between the information carrier and the touch screen, wherein the interaction is caused by a difference in the dielectric coefficient and/or the conductivity of the pattern.

A mobile terminal including a wireless communication unit configured to provide wireless communication; a display; and a back cover mounted to a rear surface of a body of the mobile terminal. Further, the back cover includes an accommodation unit formed on one surface of the back cover, and configured to accommodate a card inserted into the accommodation unit; a coil configured to convert an electric signal from the card into a magnetic signal to be transmitted to a payment machine; and a data terminal electrically connected to the coil, disposed at a position contacting a corresponding data terminal of the card inserted into the accommodation unit and configured to transfer the electrical signal from the card to the coil.

This patent specification describes a barcode-reading enhancement accessory for a mobile device having a barcode-reading capability. The accessory may include an outer case and an inner carriage. A mobile device is encased in the inner carriage, and the combination of the inner carriage and the mobile device may be accommodated in the outer case. The inner carriage is configured to accommodate a mobile device of a particular size such that a mobile device of a different size may be accommodated in the outer case using a different inner carriage. The accessory may also include an optic system to fold an optical path of a field of illumination of a light source of the mobile device and/or a field of view of a camera of the mobile device.

An optical scanner device includes at least one image capture device and a transmitter of at least one aimer beam. The scanner device determines ranging to a subject using the at least one aimer beam projected to reflect off of a surface of the subject, and detects a position of the aimer-beam reflection within an image frame captured by the image-capture device, the position being a primary indicator of a distance to the subject from the optical scanner device. A secondary indicator of the distance to the subject within the image frame in combination with the first indicator is used to help detect the aimer beam reflection against noise and detect an occurrence of an optical misalignment with possible self-correction of calibration after such misalignment.
