Abstract
Various embodiments include, for example, a digital-card reader, a reader hub, and a method of determining a coefficient of friction for mounting the digital-card reader and the reader hub to a mounting surface. In one specific embodiment, the digital-card reader includes a card-reader frame having a circuit board including at least one memory-card reader to perform data transfer operations; a magnetic material coupled to at least one face of the card-reader frame; and a compliant-region mat coupled to the at least one face of the card-reader frame and positioned proximate to the magnetic material. The magnetic material compresses the compliant-region mat to increase friction against a mounting surface to at least partially overcome insertion forces associated with inserting the memory card into the digital-card reader to reduce or eliminate lateral movement of the digital-card reader with reference to the mounting surface. Other devices, apparatuses, and methods are described.
