USB connectors are defined under standards available from the USB Implementers Forum, Inc. Different connector types have been specified over the years: A ,B, mini A, mini B, mini AB. Each type was devised for a specific market; A for the PC platform, B for peripheral devices and the mini type for hand held devices.
In order for USB communication to occur between a USB plug and a standard USB A-type receptacle, the electrical contacts of the plug have to come into contact with the electrical contacts of the standard A-type receptacle. In accordance with the physical shape definitions of a USB A-type receptacle this means that when engaged, the electrical contacts of the plug have to be enclosed within the hollow space defined by the outer shield of the standard A-type receptacle. A card-shaped device has a generally cuboid form where one of the dimensions, referred to as the “thickness” of the device, is smaller by at least an order of magnitude (factor of ten) than its other dimensions, giving the device a card-like profile. The following discussion will focus on card-like devices whose thickness dimension is less than or equal to the maximum engagement thickness of an A-type receptacle and the other two dimensions are greater than the maximum engagement width of a standard USB A-type receptacle.
