One of the the key issue with pin code is that because user tend to find them hard to remember they use well known sequence such as their birthdate. They may also use the same pin everywhere. This kind of behavior undermine the security of the system. For example using the same pin code for a credit card and a loyalty card is clearly not a good idea. However with the increasing number of application that requiers to learn a pin code, keeping a separate and unpredicable pin for each is far from being easy.
Beside using biometric authentification another interessting replacement for standard pin code is to use graphical pin code: Instead of remembering a sequence of letter/number, the user has to remember symbole/photos.
A very nice application of this idea is Passfaces where you use a set of human face as PIN code. It allow you to supply your friend/ familly face as pin code. Even more nicely it can be used in conjunction with facebook so you can use your social network data to generate the pool of photos.
