FreeBit Enters Age Tech Market with 'TONE-IN SDK' for Secure Senior Smartphone Support

Of the 30 million seniors in Japan who own smartphones, 72.4% (approximately 21.7 million) experience difficulties when using apps. Overcoming the barrier of having to rely on someone else or simply giving up, a decentralized SDK—integrating Decentralized ID (DID/VC, W3C standard) and AI service connectors through proprietary patented technology—allows businesses to support senior smartphone usage across healthcare, telecommunications, and entertainment sectors without acquiring personal information. This marks the start of chapter three for the 'TONE IN' strategy.

FreeBit Co., Ltd. (Headquarters: Shibuya-ku, Tokyo; President, CEO and CTO: Hiroki Ishida) announced its full-scale entry into the rapidly expanding Age Tech market. The company has repackaged its 27-year accumulation of proprietary patented technologies—originally introduced in July 2025 as the decentralized platform 'Portfolia'—into the integrated 'TONE-IN SDK'. This SDK realizes 'Trusted' Age Tech and marks the beginning of cross-domain business development.

'TONE-IN SDK' transforms value for both businesses and senior users. For businesses, simply integrating the library into their apps implements comprehensive support for senior users. By combining call centers, family members, and AI solutions, and securely sharing screens instantly with minimal modifications to existing systems, businesses can significantly reduce the costs of senior customer support. For users, they can call for help immediately when in trouble, whether using a newly installed or familiar app. Regardless of the support channel, consistent security governed by Trusted Web policies ensures users can safely utilize apps without handing over personal information to businesses.

The SDK repackages 'Portfolia' components—including a DID wallet, the mobile blockchain 'Trusta', SDN technology 'Emotion Link', and 'AI Connector'—into an easily integrable library for app developers. It complies with the implementation guidelines of the Japanese government's 'Trusted Web'.

FreeBit has been externally offering the safety technologies refined over 13 years by Tone Mobile as its 'TONE IN' strategy and conducting PoCs with partners. As a result, the SDK will first be deployed to Tone Mobile starting May 2026. Following this, it will expand into various domains under the corporate strategy of becoming a 'telecom-born Web3 implementation company'.

The global Age Tech market is estimated at roughly $2 trillion, with Japan leading as a hyper-aging society (29.3% elderly rate). While 30 million seniors over 65 own smartphones in Japan, 72.4% experience app-related issues, and 53.5% actually utilize third-party support. Furthermore, the 3G network shutdown in March 2026 is expected to impact approximately 3 million users.
