Soon digital security firm Gemalto's new MasterCard PayPass SIM card will make NFC payments possible on all GSM phones—whether smart or dumb. It means that you'll be able to use the SIM to manage and make mobile payments and—if it's successful—the SIM could bring the first mass commercial rollout of NFC payments across the world. And this is awesome, because it means we're another step closer to a wallet-less future. [Gemalto via Engadget]
