Micro-SIM

The micro-SIM was created for backward compatibility. The major issue with backward compatibility was the contact area of the chip. Retaining the same contact area allows the micro-SIM to be compatible with the prior, larger SIM readers through the use of plastic cutout surrounds. The SIM was also designed to run at the same speed (5 MHz) as the prior version. The same size and positions of pins resulted in numerous "How-to" tutorials and YouTube video with detailed instructions how to cut a mini-SIM card to micro-SIM size with a sharp knife or scissors.

Nano-SIM

In early 2012, the nano-SIM or 4FF (4th form factor) was introduced, which measures 12.3 × 8.8 × 0.67 mm and reduces the previous format to the contact area while maintaining the existing contact arrangements. A small rim of isolating material is left around the contact area to avoid short circuits with the socket. The 0.7 mm thickness of the nano-SIM is about 15 percent less than its predecessor. 4FF can be put into adapters for use with devices taking 2FF or 3FF SIMs.Nano-SIM cards were used by iPhone 5.

Micro-SIM is pretty much used by all leading Smart Phones, but I still doubt if Nano-SIM is accepted standard by other OEM like Nokia/Samsung as Nano-SIM was proposed by Apple only.

I do not see any problems as long as it is not a patented design that would require royalty payments.

What is its price?

 

[Sushubh]

It's not launched yet. USD 68 is the expected price.

Once the market is fully covered with micro sim's, then nano sim will be launched by the manufacturer's to provide a variation in new mobile technology. eaceful:
