This looks like a calculator for me. Its Samsung SCH-V870 mobile phone which is almost the size of a credit card. It is slightly bigger. The ultra-slim (should be thinner than Razr) handset – dubbed the Platinum Cardphone measures just 8.7 x 5.4 x 0.9cm and weighs 81g.

What amaze everyone is the handset is still able to squeeze in a 1.3 megapixel camera. Not sure about the battery life but Samsung pack it with a business card holder-like leather case.
