Abstract: In response to a fee payment request issued from an applicant apparatus via a communication network, a payment acceptance server makes a payment credit inquiry of an applicant to a financial institution server. When a payment acceptance server judges that a payment by the applicant is quaranteed, the payment acceptance server transmits to an applicant apparatus, an electronic payment certificate corresponding to a stamp, or an inspection sticker. A document with the payment certificate is transmitted from either the applicant apparatus or an agent apparatus to a document acceptance server via the communication network. Before a main body of the document is received, the document acceptance server receives from the document transmitting apparatus, compressed data which is acquired by applying one-way cryptographic function, and sets this reception timing as acceptance day/time this document.
