A transaction system receives a card into a slot between a plurality of surfaces (e.g., a first surface and a second surface) of a housing. The transaction system detects, using at least one detector, that a storage medium of the card faces the one of the plurality of surfaces at a first time while the card is received by the slot. Between the first time and a second time (that is after the first time), the transaction system prepares one of a plurality of reader interfaces (e.g., a first reader interface or a second reader interface) to read information from the storage medium in response to the at least one detector detecting that the storage medium of the card is facing the one of the plurality of surfaces. At the second time, the one of the plurality of reader interfaces reads the information from the storage medium of the card.

A point of sale (POS) device includes a nest portion and a cradle portion. The nest portion includes one or more payment card or near field communication (NFC) readers. The cradle portion couples to differently-sized interchangeable frames, which in turn help secure a mobile computing device to the cradle portion of the POS device. The mobile computing device is connected via a connector to the rest of the POS device. Payment card information read by the readers is conveyed to the mobile computing device over the connector for processing. The POS device may also include tamper detection circuitry.

A wireless electronic device may be provided with components such as electrical and structural components. During transmission of radio-frequency signals, antennas and wireless communications circuitry of the wireless electronic device may produce associated time-varying magnetic fields. One or more components may be covered with magnetic-resistant shield structures that protect the components from the time-varying magnetic fields by preventing magnetic-induced vibrations. The magnetic-resistant shield structures may include a conductive base layer such a layer of brass. A magnetic-resistant layer may be plated onto the conductive base layer. The magnetic-resistant layer may be formed from an amorphous nickel-phosphorous alloy. The amorphous nickel-phosphorous alloy may be produced by controlling the manufacturing temperature and proportion of phosphorous in the alloy while performing the plating operations within a length of time that ensures non-equilibrium conditions during the plating operations.
