What is ecard
E-cards are digital "content", which makes them much more versatile than traditional greeting cards.
Postcards and greeting cards
Like their paper counterparts, "postcards" use visual art (static or animated images or video) and provide a space for a personal note to be added. These were the first type of E-card in use. Like their paper counterparts, cyber "greeting cards" provide a greeting along with the visual art. Variations range from E-cards with fixed greetings like a paper card to selectable greetings (from drop-down lists or other selection options) to changeable suggested greetings.
