The present invention discloses a card reader and a mobile payment terminal. The card reader comprises an MCU which is connected to a single interface smart stage card and is configured to read data from the single interface smart stage card or write data in the single interface smart stage card; an NFC antenna which is connected to the MCU and is configured for performing data interchange between a contactless card reading terminal and the single interface smart stage card; and a DIU which is connected to the MCU and is configured to realize communication between the MCU and a communication terminal. In this way, by installing an NFC antenna, the single interface smart stage card in the card reader can interchange data with a contactless card reading terminal wirelessly without connecting to the DIU.
