  • Patent number: 11366995
    Abstract: Methods and systems disclosed herein may communicate information, such as alerts and notifications, to a cardholder via a color-changing transaction card. In particular, the cardholder may configure one or more thresholds that establish when a transaction card may change colors. For instance, a transaction card may change colors at, or while approaching, a first threshold. The transaction card may change colors at, or while approaching, a second threshold. When the cardholder's balance goes below the thresholds, the transaction card may revert back to the lower threshold color or the original color of the transaction card. Using the techniques described herein a financial institution may convey information to a cardholder in a way that does not require the cardholder to digitally engage with the financial institution.

  • Patent number: 11320679
    Abstract: In a display device including a connection portion pressure-bonded with an anisotropic conductive film and an FPC, a closed circuit configured to allow an abnormality, such as a connection failure in the connection portion, or disconnection or a short circuit in a wiring line of the FPC to be detected, is provided separately from a wiring line needed for displaying an image. When an abnormality occurs, a resistance value of the closed circuit changes, and thus a current value of current flowing through the closed circuit changes. As a result, even when an image is displayed, a detection circuit detects a change in a value of voltage applied to the closed circuit and notifies a user, and thus the user can know that an abnormality occurs in the connection portion or the wiring line of the FPC.
