  • Patent number: 10910293
    Abstract: A leadframe includes a die pad having a plurality of sides which collectively define the rectangular die pad area including at least two securing sides that include a linear portion with a cantilever interrupting the linear portion. The die pad has a top surface defining a top plane and a bottom surface defining a bottom plane. Lead terminals are beyond the die pad. The cantilevers have a fixed end and a free end opposite the fixed ends that enables flexing or bending responsive to a received force. The free ends include a distal end with an electronic component locking feature. The fixed ends are positioned beyond the die pad area, and the electronic component locking feature extends inward over the rectangular die pad area for providing mechanical support and for securing the electronic component.

  • Patent number: 10515363
    Abstract: A card reader configured to read a smart card can be detachably connected to a mobile computing device. When the card reader is attached to the mobile device, an application installed on the mobile computing device permits the mobile device to communicate with the card reader in order to process transactions. Security measures can be used on the mobile device to prevent theft of a PIN during software PIN entry of a payment transaction. The mobile device can prevent the keypad or other input interface from displaying feedback. The mobile device can also prevent passcodes from being stolen by displaying media encoded with digital rights management (DRM) and by managing the media and user inputs at a secure server. A mobile device can securely communicate with a card reader for a payment transaction using asymmetric or symmetric encryption.
