An enclosed re-programmable non-volatile memory card includes a cover that is hinged to the card to normally cover a set of external contacts to which the memory is connected but which can be rotated out of the way by hand to expose that set of contacts for connection with a mating receptacle of a host device. A second set of electrical contacts having a different pattern than the covered set may also be provided on the card. The covered set of contacts may be in accordance with the universal serial bus (USB) plug standards. A latching mechanism built into the hinged cover holds it firmly in a closed position but allows its manual release to expose the covered set of contacts. One exemplary release mechanism utilizes a resiliently held element that is moveable by hand against the resilience, and another employs a hand slideable latch.
