Abstract
A data read/write device capable of reading SIM (Subscriber Identity Module) card includes a SIM card slot, into which a SIM card is inserted and read; an internally provided SIM card connector for transmitting data of the SIM card inserted in the SIM card slot; a microprocessor for receiving and reading data of a SIM card transmitted from the SIM card connector, and a SIM card carrier detect (CD) pin provided between the SIM card connector and the microprocessor for detecting any SIM card in the SIM card slot. The SIM card CD pin is capable of informing the microprocessor to stop reading data of SIM card when the SIM card is withdrawn from the SIM card slot, so that the microprocessor is prevented from burning out due to faulty operation or falling into infinite loop of reading.
