Abstract
A memory card identification method and a mobile device are provided. The memory card identification method includes: sending an initialization command of a first-type memory card communications protocol to a to-be-identified memory card; detecting whether there is a response in a command pin of the memory card; and identifying the memory card as a first-type memory card or a second-type memory card based on a response status of the command pin.
