Of course, with the implementation of smart cards, one of the main concerns is security. For Mobile FeliCa, you can remotely lock the smart card function either via email or phone call to prevent unauthorized use.

Other features include a motion sensor which opens the doors to various mobile games. In a demonstration over at Sharp's booth at 3GSM, a representative illustrated the scenario of a commuter who had run out of money to purchase a can of drink from a vending machine. With Mobile FeliCa, the user need only flash his mobile phone which has a non-contact smart card embedded, and the vending machine would automatically release a can of coke (or whatever the machine is meant to dispense).

Our take: Interesting concept, but security remains as one of the key concerns.
