Abstract:
1. A digital appliance comprising: a slot structure having a slot opening to allow a first type memory card having a first set of contacts to be removably connected by insertion into the slot structure, the slot structure having formed therein a mechanical structure including: the second type memory card having a second set of contacts, where the first and second sets of contacts differ by at least one of the contacts, and the first and second type memory cards having a similar form factor except for the indentation along a first edge of the first type memory card, the first edge being other than a second edge of the first type memory card inserted into the digital appliance when the memory card is inserted into the slot for connection thereto, the first and second edges defining an angle therebetween, whereby the mechanical structure prevents the connection of the second type memory based on the lack of the indentation.
