Strengths of IWI
Providing the value of "trust," essential for a sustainable society, through an IT platform that securely connects diverse data
A future society in which all information is digitized and connected, enabling the resolution of social issues and economic development to go hand in hand.
In 1989, we developed a network gateway system that processes large volumes of communication data in real time, and have continued to support the idea that "it is natural to be able to use cards safely 24 hours a day, 365 days a year."
IWI pursues value to support the structure of society in all areas.

Prologue
A pioneer of cashless society that has changed the times
The origin of the company name IWI is "to cause a shock wave that will change the times." The company started its business in 1984, at the dawn of cashless payments in Japan. In 1989, it developed "NET+1," which provides network connection functions and authorization functions necessary for card payments in real time 24 hours a day, 365 days a year. It has been highly praised by financial institutions, building relationships of trust and establishing a solid position in the industry. In 1999, it developed "ACEPlus," which detects fraudulent use of credit cards, contributing to the establishment of safe and secure cashless payments. "NET+1" and "ACEPlus" still maintain the top market share today, and continue to provide the value of "trust" by responding to cloud computing and cross-industry platformization.
Business Expansion
Expanding business areas by applying core technologies cultivated in payment
IWI has broadened the scope of its business by applying the core technologies it has cultivated in payment, such as communications, data processing and analysis, and security, to various fields. In 1991, it developed a unique data processing and analysis product for the securities industry. It supports the industry with an IT infrastructure that can reliably exchange large amounts of data in real time. In 2003, it applied its card fraud detection technology to develop CWAT, a product to prevent internal information leaks from companies, and entered the security business. Furthermore, in 2019, it has expanded its field of challenge beyond finance, developing a system for the broadcasting industry.


Transformation for the Future
Evolving IT infrastructure to support society and create "new trust"
Currently, IWI is working to develop new solutions to solve various social issues by combining its core technology with cutting-edge technologies such as AI and strengthening external partnerships. In a future society where solving social issues and economic growth go hand in hand, an IT infrastructure that can exchange a wide variety of large amounts of data faster and in a safer and more secure environment will be important. Based on the core technology it has cultivated in the payment field, IWI will support society with its IT infrastructure, create "new trust" and bring value to people's lives.
