본 발명은 개인 휴대용 무선통합단말기를 통한 전자상거래 시스템 및 그 방법에 관한 것으로서, 보다 상세하게는 개인 휴대용 무선통합단말기를 통해 보안인증을 거친 후 상품검색 및 상품의 현장 정보처리를 가능하게 할 뿐만 아니라 신용카드결제 및 매출전표의 발급이 가능하도록 한 개인 휴대용 무선통합단말기를 통한 전자상거래 시스템 및 그 방법에 관한 것이다.The present invention relates to an electronic commerce system and method through a personal portable wireless integrated terminal, and more particularly, to enable product search and on-site information processing of the product after undergoing security authentication through a personal portable wireless integrated terminal. The present invention relates to an electronic commerce system and a method through a personal portable wireless integrated terminal which enables the issuance of a credit card payment and a sales slip.

전자상거래는 산업의 전분야에 걸쳐 수행되고 있는 실정이다.E-commerce is being carried out throughout the industry.

그런데, 인터넷을 통해 전자상거래를 수행할 경우 사용자들에게 전자상거래가 이루어지고 있음을 알려야 하는 것이 가장 큰 문제인데 이를 해결하기 위한 방법으로는 위에서도 언급한 바와 같이 다른 사이트들에 자신의 배너광고를 실어 자신의 전자상거래 사이트를 방문하도록 유도하거나, 전자메일을 통해 자신의 전자상거래 사이트를 소개하여 방문을 유도하고 있다.However, when conducting e-commerce through the Internet, the biggest problem is to inform users that e-commerce is taking place. As a way to solve this problem, as mentioned above, a banner advertisement is displayed on other sites. They are encouraged to visit their e-commerce site or introduce their e-commerce site through e-mail to encourage visits.

한편, 다른 방법으로는 인터넷을 통해 스스로 모든 것을 해결해야하는 불편함 등을 해소하기 위해 개인이 휴대할 수 있는 무선통합단말기인 개인용휴대단말기(Personal Data Assistant ; 이하, PDA라 함)를 소지한 회사의 사원을 인터넷을 사용할 수 없거나 사용하고 있지 않는 현장 등에 파견하여 직접 소비자를 상대로 회사의 상품을 홍보하고 구매하도록 유도할 수도 있다.On the other hand, the company has a personal data assistant (PDA), a wireless integrated terminal that can be carried by individuals to solve the inconvenience of having to solve everything on its own through the Internet. Employees can also be dispatched to sites where the Internet is unavailable or unused, to directly promote and purchase the company's products to consumers.

그런데, 위와 같이 PDA를 소지한 사원이 직접 회사의 상품을 PDA를 통해 회사의 상품을 검색하고 설명할 수는 있지만, 소비자의 요구사항에 따라 적절하게 현장에서 변경, 조합하여 소비자의 요구에 맞도록 상품을 재조정하고 소비자의 요구에 따른 정보를 조회하는 등의 현장 정보처리 기능을 수행하지 못하고 있으며, 현장에서 상품을 신용카드를 통해 구매하고자 할 경우에는 비용결제의 문제로 인해 현금거래만을 이용하거나 신용카드 가맹점에서만 거래를 할 수 있는 문제점이 있었다.By the way, the employee who owns the PDA can directly search and explain the company's products through the PDA, but according to the customer's requirements, it is possible to change and combine them on site to meet the needs of the consumers. It is not able to perform on-site information processing functions such as re-adjusting the product and inquiring information according to the consumer's request.If you want to purchase the product through the credit card in the field, you can only use cash transactions or credit due to the problem of payment. There was a problem that can only trade in card merchants.

그래도, 신용거래를 할 경우에는 전화를 통해 신원확인을 한 후 결제를 하고 매출전표는 차후에 승인을 받은 후 우편이나 인편 등으로 전달해야되기 때문에 소비자에게 신뢰성의 문제와 영수증의 분실 등의 불편과 비용이 낭비되는 문제점이 있었다.Nevertheless, in the case of a credit transaction, payment must be confirmed by telephone and the sales slip must be sent afterwards by mail or in person after receiving approval. There was a wasteful issue.

또한, 검색된 상품 등을 출력하여 자료로 제공하고자 할 경우에도 프린터가 내장되지 않아 미리 인쇄된 팜플렛만을 제공하게 되는 문제점이 있다.In addition, even if you want to output the searched products and the like to provide as a material there is a problem that only the pre-printed brochure is provided because the printer is not built.

본 발명은 상기와 같은 문제점을 해결하기 위해 창작된 것으로서, 본 발명의 목적은 개인 휴대용 무선통합단말기를 통해 상품검색 및 상품의 현장 정보처리를 가능하게 할 뿐만 아니라 신용카드결제 및 매출전표의 발급이 가능하도록 한 개인 휴대용 무선통합단말기를 통한 전자상거래 시스템 및 그 방법에 관한 것이다.The present invention was created to solve the above problems, and an object of the present invention is not only to enable product search and on-site information processing of goods through a personal portable wireless integrated terminal, but also to issue credit card payment and sales slip. The present invention relates to an electronic commerce system through a personal portable wireless integrated terminal and a method thereof.
