Can you use your mobile phone to monitor your health, store and transfer money, and watch movies, as well as talk with your partner on the other phone with his/her image clearly visible on the screen? Well, now you can. Nokia has already developed prototype phones fitted with biosensors that can monitor your heart and breathing rates as well as blood sugar levels. They can be connected to a central computer system of your doctor, so that any worrying changes can be immediately addressed. Mobile commerce is already here! Smartphones are being used for shopping and to transfer money. Cell phone users in Japan are able to buy air tickets from their Smartphones, while users of such phones in Philippines, East Africa and Afghanistan can transfer money from these handsets without going to a bank! Work is under way to ensure high quality encryption of messages so that customer security can be guaranteed.
