NTT DOCOMO develops SIM-based authentication mini device

10 Jun 2014

Japanese cellco NTT DOCOMO has developed a prototype of what it claims is the ’world’s first SIM-based authentication device’, which 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. According to a company press release, ‘Portable SIM’, which comprises three major modules – SIM card, Bluetooth and NFC – is expected to be incorporated in a number of convenient wearable devices after further downsizing. Portable SIM can securely store multiple credentials, such as IDs and passwords, so it can also theoretically be used alongside PCs and other connected devices.
