A datacard is an electronic card for data operations (storage, transfer, transformation, input, output). ==Datacard types== Datacards can be sorted by their purposes: # Expansion card – printed-circuit board: inserted in a special slot in the device and used to add functions to this device; # Memory card or flash card: a card which is inserted into the corresponding device socket and used for data storage and transmission; # Identification card: a card that works by a contact/contactless interface and contains the data used for performance of various functions, for example access control in subway or offices. It is also used for prepaid services like banking and telecom; # Datacard or "electronic card": a card dealing with e.g. geographical, climatic, road or topographical data to be displayed on the video screen of some device (computer or GPS navigator), or represented otherwise to be more convenient to use in a certain situation (for example, navigator’s vocal instructions). 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Datacard」の詳細全文を読む スポンサード リンク
