A safe bet we will see plenty of activity, more details in Japanese, on this platform [Eds]
NTT DOCOMO, INC., a personalized solutions provider for smarter living, announced today that it has developed a prototype of the world’s first SIM-based authentication device, named Portable SIM, that can wirelessly activate any compatible smartphone or tablet for network-access authentication with a simple wave to replace the mobile device’s SIM function with securely stored subscriber identity information.
Portable SIM incorporates three major modules: SIM card, Bluetooth and NFC. The pocketsize mini device is expected to be incorporated in convenient wearable devices after further downsizing.
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. DOCOMO will also study ways to link Portable SIM and other smart devices, such as TVs, music players and in-car informatics systems, to bring convenient services and products to customers.
