본 연구는 백화점 고객이 신용 카드 신청 요구 시에 작성되는 가입 정보 및 사용되고 있는 고객의 거래 정보는 카드 사용 패턴으로 신용도를 예측하는 여러 방법론을 제시하고 성능을 비교하였다. 가입 정보를 분석하기 위해 역전파 신경망(Back-Propagation Neural Network, BPNN), 사례기반추론(Case-Based reasoning)을, 거래 정보를 분석하기 위해 역전파 신경망과 더불어 시간지연 신경망(Time-Delayed Neural Network, TDNN)을 각각 사용하여 그 결과를 비교하였다. 또한 전체시스템의 적중률을 높이기 위햐여, ID3와 신경망을 이용한 Meta-Leaning 방법을 제시하였으며, Meta-Learning 방법과 다른 방법들을 비교, 분석을 하였다. 본 연구에서는 모형 수립과 검증을 위하여 T백화점의 실제 신용 카드 가입 고객 데이터를 이용하여 실험하였다. 데이터의 성격에 따라 각 모델의 예측력에는 차이가 나타났으나, 신경망 모형의 예측력이 우수하였으며, 시간적 특성을 고려하는 시간지연 신경회로망 모형의 예측력은 더욱 우수하게 나타났다. 또한 Meta-Learning 모형을 사용하면 예측력이 더 높아진다는 것을 확인할 수 있었다.

신용카드를 이용한 결제가 증가하고, 카드 사용 건수가 증가하면서 신용카드의 사용이 대중화 되었다. 그에 따라 모든 거래에서 카드 결제 요구가 증가하고 있지만, 기존의 무선 카드 결제기는 고가이고, 현장에서 사용하기 불편하여 사용분야가 제한되고 있다. 특히 운송/운수 및 방문판매업 분야와 같이 현장에서 카드 결제를 직접 수행하여야 하는 경우에는 기존의 카드결제기를 사용하는데 있어 여러 가지 문제점들이 있어왔다. 본 논문에서는 사용자가 일상적으로 사용하는 휴대폰 등의 모바일 단말과 연동하여 카드 결제가 가능하도록 하는 휴대형 모바일 카드 리더기와 이를 이용한 유비쿼터스 카드 결제 시스템을 제안한다. 개발된 시스템은 항시 휴대하는 휴대폰과 연동하여 사용이 가능하므로 언제 어디서나 카드결제가 가능하도록 하는 특징이 있다.
