The current electronic transactions are likely to utilize communication methods through advanced and proactive electronic technologies. However, electronic transactions are supported by the laws, requiring certification for legal status of digitized data or data messages functionally equivalent to manual records or written evidence, certification for sending or receiving data messages, electronic signature, and data messages adduced as evidence for the court hearing. With purposes to provide sound legal effects to transactions in the form of data messages functionally equivalent to traditional transactions, the Electronic Transactions Act B.E.2544 was promulgated and enforced since April 3, 2002. Subject to Section 36 of this Act, the Electronic Transactions Commission empowers Minister of the Science, Technology, and Environment as a chairperson and Director of National Electronics and Computer Technology Center (NECTEC), National Science and Technology Development Agency (NSTDA) as a committee and secretary. In 2002, The NECTEC established Office of the Secretariat to the Electronic Transactions Commission to serve as a secretary to the Commission under the prescribed laws. Later, after Ministry of Information and Communication Technology (ICT) was founded, alterations were also made in the Electronic Transactions Act. The chairperson of the Electronic Transactions Commission was then changed from “Minister of the Science, Technology, and Environment” to “Minister of the Information and Communication Technology” subject to Section 102 of the Royal Decree Alternating Provisions to Comply with Transfer of Powers in the Public Sector under the Act for Improvement of Ministry, Office, and Department B.E.2545.
The Electronic Transactions Act No.2 B.E.2551, effective since February 14, 2551, has added components of the Electronic Transactions Commission hereby; Permanent Secretary of the Information and Communication Technology serving as a vice-chairperson and Head of the Electronic Transactions Commission’s Office as a committee and secretary. Meanwhile, Office of the Electronic Transactions Commission is regarded as the public sector under Office of the ICT’s Permanent Secretary. The Office of the Electronic Transactions Commission was officially established on August 16, 2011.
