There are three main types of hologram:

The first being the most complex involves projecting a realist 3d image of an object or person. These are often featured in science fiction, for example in the Star Wars films Princess Laya. Something slightly closer to an holographic generator creates an optical illusion. This is done by placing an object inside a bowl and it is reflected on the top surface where the mirrors are curved to make it look 3d. The image below shows an example of this:


The next is a 3d holographic sticker, often used as a security device for example on passports. It is used to authicate the documents it appears on as it is very hard to counterfit. http://www.hologramhotstamping.com/why_hologram.htm


The last is a 2d and is used to show movement or change. This technique is often used for entertainment purposes on postcards, celebration cards and sometime for business cards. The image changes as it is tilted to reveal the sequence. Examples of these are shown below:

I really like the interaction you have with these items, as you are in control of the speed of the movement and it’s always rewarding to reveal the sequence. Although these are simplistic and it’s not a particular mind blowing technique it still gives an edge over plain cards. Also I personally like the textured feel of the holographic card and it’s a great thing to show and share.
