DoCoMo app shares SIM credentials with offline devices

Japanese mobile carrier NTT DoCoMo has developed an app that can wirelessly send authentication credentials to devices that are not connected to the Internet, allowing more hardware to get online or query the cloud.

Potential applications of the technology include the ability to share mobile SIM user credentials such as phone numbers among multiple devices without the need to physically transfer a SIM card. It could also be used for giving online access to IoT (Internet of Things) hardware.

Based on prototype hardware announced last year, the Portable SIM App for Android can transfer data with a wave of a hand. The carrier is exhibiting the app at Mobile World Congress this week in Barcelona.
