The new iPad has introduced more than just loads of features, ease of use and portability. It has introduced some new evolution in technology too. And the newest evolution - introduction of Micro SIM-card.
One of the new features of iPad viscera besides the A4 chip , is that it's using a micro-SIM card for its 3G features.
Micro-SIM card, is the next generation of the conventional SIM card that we've been using. Micro SIM Card utilises 3FF - or Third Form Factor. In simple terms, It uses a new designing which provides physically smaller,less blubber and shiny gold contact area.
The contact area, where the whole technology works, is of the same size as of its ancestor. You can see it very easily in the given picture.
But thats not all. It allows to accomodate more stuff. It allows backward-compatability with a physical adapter(just the way RS-MMC is to regular MMC).
Micro SIM has a bigger internal phonebook,and also allows supports email storage. It also supports a new authentication scheme that fights carrier spoofing.
Now as the contact surface is of the same size and material electrically, there is a chance that you can size down your old SIM card, so that they fit inside physically in the slot, and use them in the micro SIM slot.
Now lets see what happens. The success of micro SIM also depends on the success of the iPad.
What do you think ?? Will Micro SIM will be a success? Feel free to pour in your comments
