Prevent RFID key card duplication

Recently I have seen several companies that are making duplicates of key fobs and cards. The most popular in my area is that also makes standard keys and car keys. With this comes a concern for building security.

I was wondering, what can be done to prevent key card duplication? Is there some type of proprietary card that can't be easily copied?
