The Uniform Customs and Practice for Documentary Credits(UCP) have been used for over 60 years to govern the operation of documentary credits. While the UCP have been extremely successful in providing self-regulation for the letter of credit industry, the need was apparent to update the rules to accommodate technological advances.In response, the Banking Commission of International Chamber of Commerce(ICC) established a working group consisting of experts in the related fields to prepare the appropriate rules as a supplement to the UCP. The result is the new Supplement to Uniform Customs and Practice for Documentary Credits Publication No. 500 for Electronic Presentation: eUCP. This new electronic supplement was approved by the ICC in end December 2001 and came into force on April 1, 2002.In developing eUCP Version 1.0, the ICC has taken a major step in encouraging international traders to accommodate presentation of electronic records alone or in combination with paper documents. The eUCP only applies in cases when eUCP must be specifically incorporated into the credit. The eUCP is not a revision of the UCP. The eUCP is a supplement to the UCP that, when used in conjunction with the UCP, will provide the necessary rules for the presentation of the electronic equivalents of paper documents under letters of credit. The 12 Articles of the eUCP cover a range of issues including the format of electronic records, presentation, examination, Corruption of an Electronic Record after Presentation and Additional Disclaimer of Liability for Presentation of Electronic Records. Some problems of new eUCP Version 1.0 exist such as format, presentation of electronic records, examination and beneficiary's notice for completeness.In anticipation of expectation and to meet the electronic trade transactions, it is necessary to provide more detailed guide of the banking operations and developing rules for electronic letters of credit.
