An E-card is an electronic postcard or greeting card, with the primary difference being that it is created using digital media instead of paper or other traditional materials. E-cards are made available many different ways, usually on various Internet sites. They can be sent to a recipient virtually, usually via e-mail or an instant messaging service. Since e-cards are digital "content", they are highly editable, allowing them to be extensively personalised by the sender. They are also capable of presenting animated gifs or video.
