Background: Access Control as a Management Challenge in the Hybrid Work Era With the normalization of telework and office decentralization, traditional IC card-based access control systems face three major hurdles: difficulty in centralized management across multiple locations, high system update costs, and complex audit/security compliance. There is a surging demand for next-generation, cloud-compatible solutions that offer API integration, particularly among companies holding ISMS and Privacy Mark certifications.

Latest Case Study: Full-Scale iDoors Implementation at PSC PSC Co., Ltd. revamped its access control system during the relocation and expansion of its Tokyo headquarters, implementing AT Works' 'iDoors' across the entire company as of May 2025. A manager at PSC stated, 'Compared to our old system, the response speed is vastly superior. We are also considering API integration with our attendance and seat reservation systems to further improve operational efficiency.'

Regional Contribution: Partner Registration with the Toyama DX Consortium AT Works has registered as a partner in the 'Toyama DX Consortium' promoted by Toyama Prefecture, intensifying its efforts to support the digital transformation of local businesses. The consortium includes major regional players such as Toyama Bank, Hokuriku Bank, Toyama First Bank, and Sugino Machine. AT Works' server and iDoors solutions are expected to serve as infrastructure for regional DX. The company's 'bridge strategy,' connecting cutting-edge technology from Roppongi, Tokyo, with local industries in Toyama, is a notable model for balancing regional revitalization with IT industry promotion.

Expansion of Integration with Accommodation Management Systems AT Works is also advancing the integration of iDoors with accommodation management systems, accelerating its expansion into the hotel and ryokan market. By achieving full digitization of check-ins and room keys, as well as centralized management of access data, the company is contributing to the DX of the hospitality industry.

iDoors Strengths and Performance Metrics Leveraging the in-house development capabilities cultivated since its establishment in October 2009, AT Works has evolved iDoors from a simple 'key management system' into a 'management information platform.'
