Abstract
In a contactless memory card system, a means is provided for sending a transmission wait request signal to the memory card when yet-to-be-passed received data remains in both the serial data receiving circuit and received data buffer via an electromagnetic coupling interface section, thereby preventing overrun errors even when the reading by a microcomputer of reader/writer received data is slow.
