In this paper, I examined the trends of standardization and electronization of trade documents and SWIFT network. Also, I reviewed on emerging electronic documentary credit for electronic payment and electronic presentation of documents. New international trade customs and practices are being established and changed as a result of the growth of the Internet and other on-line networks. At the same time there is increasing pressure to move from existing paper-based documentary credit to electronic documentary credit. Several projects devoted to development of an electronic letter of credit infrastructure have recently been proposed such as Bolero, SWIFTNet, UNeDocs and eUCP, etc. Yet, little can be done until the presentation process is electrified between traders and banks. Also, interbank communication of letters of credit has long been electronic, mainly through the SWIFT. However, it is not functioned between applicant and beneficiary, although the solution of SWIFTNet has recently been developed. The Banking Commission of International Chamber of Commerce established a working group consisting of experts in the related fields to prepare the appropriate rules as a Supplement to UCP 500 for Electronic Presentation: eUCP. The eUCP will provide the necessary rules for the presentation of the electronic equivalents of paper documents under letters of credit. Some problems of electronic presentation under the eUCP, exist such as format, presentation of electronic records and the way of beneficiary's notice for completeness under the Article e5 if more than one record is to be presented electronically by third parties. Therefore, it is encouraged to provide more detailed guide for eUCP Article e5.
