Device and method for detecting insertion direction of sim card

Abstract

Disclosed are a device and a method for detecting a reversed insertion of the SIM card into a SIM card socket unit in the terminal. The device includes a SIM card socket unit including a detection terminal that is disposed at a position to be contacted with a GND terminal of the SIM card, and when the SIM card is inserted, and outputs a voltage received from a contacted terminal of the SIM card. The SIM card socket unit having received the voltage from the detection terminal is transmitted to a controller as a SIM card insertion direction detection signal. When the SIM card insertion direction detection signal received from the SIM card socket unit is a reversed insertion detection signal, the controller is configured to inform the user that the SIM card is inserted in a reversed direction.

Dependencies are inferred from the claim text.
