Abstract
Computer-based application systems encounter a case in which data must not exist in a plurality of storage devices. This problem emerges typically in translocating data. The invention disclosed here is intended to erase data in its original location promptly after it has been translocated. The invention comprises a memory card containing a processor and a storage device wherein the memory card is connected to an external processing apparatus. In response to a command issued by the processing apparatus, data is erased from the memory card just after it is copied to the processing apparatus. Thereafter, the data stored in the processing apparatus may be transferred to a second memory card.
