In Article 2B, a contract can exist even if no human being reviews or reacts to the electronic message or the information delivered. This adapts traditional theories of consent and agreement to electronic commerce. The default rules are limited to acknowledgment of electronic messages. There, the effect of a request for acknowledgment depends on whether the request made the message conditional on acknowledgment or merely requested acknowledge. As a basic principle, the message sender can control the legal effect of its messages if it does so expressly.
Acknowledgment confirms receipt.
This section deals with functional acknowledgments. It does not create presumptions other than that an acknowledgment indicates that the message was received. Questions about accuracy of the received message and about time of receipt, content and other issues are not treated.
