     상기 본 발명에 따르면, 전자화폐는 현금이나 신용카드보다 훨씬 더 편리하고 안전함에도 사용할 수 있는데도 불구하고 널리 전파되지 못하고 있는 실정이다. 특히 인터넷 상에서 디지털 컨텐츠를 제공하는 인터넷 사업자들에게 절실히 필요한 소액 결제시스템에 최적격인 전자화폐가 활성화 되지 못하고 있음으로, 이에 따른 대책이 시급한 실정이다. 그런데 최근 국세청에서 시행하고 있는 신용카드 영수증 복권제도가 신용카드 사용을 활성화 시키는 것에서 볼 수 있듯이, 전자화폐에도 복권제도를 적극적으로 도입한다면 큰 효과가 있을 것으로 예상된다. 
     본 발명은 상기한 전자화폐의 사용을 촉진시키기 위해서 복권 추첨을 하는 과정에 있어서, 전자화폐의 소비자들의 흥미를 끌 수 있고 또한 누구나 쉽게 납득할 수 있는 공정한 복권 추첨의 방법을 제공하기 위해 창안된 아이디어다.
