Abstract
A storage card is capable of sharing a card slot with a standard SIM card. A missing corner edge used for defining a mistake-proof missing corner is disposed on each of the storage card and the standard SIM card. When another edge of the storage card overlaps another edge of the standard SIM card, at least a part of the missing corner edge of the storage card is located on an outer side of a projection line that is of the missing corner edge of the standard SIM card and that is on the storage card. A storage wafer is disposed in the storage card, and a vertex angle of the storage wafer falls between the missing corner edge of the storage card and the projection line.
