Japanese mobile carrier NTT Docomo has showcased a new prototype device dubbed Portable SIM.

The company says the prototype device is a SIM-based authentication device that can wirelessly activate any compatible smartphone or tablet for network access. The NTT Docomo Portable SIM includes three modules - SIM card, Bluetooth and NFC.

The idea behind the NTT Docomo's Portable SIM is that it can enable SIM-less tablets to make phone calls or a single SIM smartphone to use another SIM for various functions. The device also allows users to switch subscriber identity to the mobile device via Bluetooth, eliminating the need to physically insert a SIM card and replacing it with a simple tap.

Describing the Portable SIM, NTT Docomo said, "The smartphone user can switch their subscriber identity from a personal device to a shared tablet in the workplace. For security, the switched phone number in the smartphone is locked once the Bluetooth link is broken."

NTT Docomo, as of now, showcased the Portable SIM device in an enclosed white box including the SIM card. However, the company claimed that the pocket-sized mini device would be further incorporated in convenient wearable devices after further downsizing.

The company further said the "Portable SIM can securely store multiple credentials, such as IDs and passwords, so it also can be used with PCs and other connected devices to eliminate the need to type in such information when accessing online-shopping and other sites. Going forward, Docomo will continue to study key technologies, functions and service applications before commercialization of the device."
