External device for mobile communication terminal and NFC method using the same
First Claim
1. An external device for a mobile communication terminal, comprising:
- a serial communication unit connected to a mobile communication terminal body through a connector;
a Near Field Communication (NFC) unit for communicating with the mobile communication terminal body through the serial communication unit and communicating with an outside via non-contact NFC;
a smart card unit for communicating with the NFC unit; and
an antenna configured such that the NFC unit transmits/receives signals via non-contact NFC through the antenna.

Abstract
Disclosed herein are an external device for a mobile communication terminal, which enables non-contact NFC with the outside through a Near Field Communication (NFC) unit, and an NFC method using the external device. The external device for a mobile communication terminal includes a serial communication unit, an NFC unit, a smart card unit and an antenna. The serial communication unit is connected to a mobile communication terminal body through a connector. The NFC unit communicates with the mobile communication terminal body through the serial communication unit and communicates with the outside via non-contact NFC. The smart card unit communicates with the NFC unit. The antenna is configured such that the NFC unit transmits/receives signals via non-contact NFC through the antenna.
