Apple's iPhone 5 uses a nano SIM, the smallest SIM ever designed and, quite possibly, the last SIM we'll see in any mobile telephone.

The nano SIM used in the new smartphone is tiny and its pattern of electrical contacts are about two thirds the size of the original SIM. It's almost too small to hold and certainly small enough to lose in a pocket, but despite the diminutive size its basic functionality remains unchanged: hosting encryption electronics and serial communications at 9,600 baud.

Hello,

This is really interesting and detailed information about the way SIM cards work. The graphic is also very explicative.

Thanks in advance.
