본 발명은 이동통신 단말기에 관한 것으로, 보다 상세하게는 바코드를 이용하여 데이터를 교환할 수 있는 장치 및 방법에 관한 것이다.The present invention relates to a mobile communication terminal, and more particularly, to a device and a method for exchanging data using a barcode.

현재 이동통신 단말기간에 데이터 교환 방법은 여러가지 방법들이 있다.Currently, there are several methods for exchanging data between mobile terminals.

첫째로, 적외선 포트(Infrared Ray Port)를 이용하는 방법은 이동통신 단말기간에 적외선 포트를 마주보게 하고 데이터 송신 버튼을 클릭하면 필요한 정보를 간단하게 보낼 수 있고, 무선으로 파일을 전송하고 별도의 프린터 케이블 없이 원하는 문서의 인쇄도 가능하게 된다. 그러나 상기 두 단말기 모두 적외선 포트가 있어야 하며, 연결하는 시간이 걸리고, 전송내내 상기 두 단말기의 포트를 맞춰줘야 한다.First, the method of using the Infrared Ray Port is to send the necessary information simply by facing the infrared ports between mobile communication terminals and clicking the data transmission button. It is also possible to print desired documents. However, both terminals must have an infrared port, take time to connect, and have to match the ports of the two terminals throughout the transmission.

둘째로, 블루투스(Bluetooth)를 이용하는 방법은 이동통신 단말기간에 블루투스 연결을 설정한 다음 데이터를 전송한다. 그러나 문제점은 상기 두 단말기 모두 불루투스 접속장치를 가지고 있어야 하고, 연결시간이 오래 걸리고, 인증등 복잡한 과정을 거쳐야 한다.Secondly, the method using Bluetooth establishes a Bluetooth connection between mobile communication terminals and then transmits data. However, the problem is that both terminals must have a Bluetooth connection device, the connection takes a long time, and must undergo a complicated process such as authentication.

셋째로, 이동통신망을 이용하는 방법은 이동통신망을 통해 데이터를 전달하면 수신측에서 상기 데이터를 받을수 있다. 그러나 이동통신망을 이용하므로 과금이 든다.Third, the method using the mobile communication network can receive the data at the receiving side when the data is transmitted through the mobile communication network. However, there is a charge because it uses a mobile communication network.

마지막으로 케이블을 이용하는 방법은 USB등 케이블을 이용하여 PC에 데이터를 백업한 후 다시 상대방에게 전송하는 방법이다. 그러나 PC가 있어야 하고, 연결하는 시간과 PC에 이동통신 단말기를 인지하는 소프트웨어가 있어야 한다는 단점이 있다.Finally, the method of using a cable is a method of backing up data to a PC by using a cable such as a USB and then transmitting it to the other party. However, there is a disadvantage in that there must be a PC, the time to connect, and the software to recognize the mobile communication terminal in the PC.

본 발명의 목적은 이동통신 단말기간에 바코드를 이용하여 보다 간편하게 데이터를 교환할 수 있는 바코드를 이용한 데이터 교환 장치 및 방법을 제공하는데 그 목적이 있다.An object of the present invention is to provide an apparatus and method for exchanging data using a bar code that can exchange data more easily using bar codes between mobile communication terminals.
