Showcase Provides 'ProTech ID Checker' for Identity Verification of Kintetsu Cable Network's MVNO Subscribers

Showcase Co., Ltd. (Minato-ku, Tokyo; President and CEO: Koichi Matsumoto; TSE Code: 3909; hereinafter 'Showcase'), a provider of DX cloud services connecting businesses and customers, has provided its identity verification tool 'ProTech ID Checker' to Kintetsu Cable Network Co., Ltd. (Ikoma, Nara; President and CEO: Katsuhito Kuwahara; hereinafter 'KCN') for use in identity verification procedures for its MVNO service.

This enables high-security online identity verification using the Public Key Infrastructure (JPKI) and eKYC for authenticating users during contract changes on the MVNO subscriber portal.

Background of ProTech ID Checker Adoption

KCN began exploring identity verification methods using IC chips on official identification documents, prompted by the partial amendment of the Act on Prevention of Unfair Use of Mobile Phones, which took effect on April 1, 2026. Among several services evaluated, 'ProTech ID Checker' was selected due to its cost-effective pricing model suitable for small-scale deployment, its automated matching function that reduces verification workload, and its seamless integration into existing systems.

KCN has now commenced operations using 'ProTech ID Checker' as the authentication method for contract changes on the MVNO subscriber portal. This allows users to complete identity verification securely and smoothly online, while ensuring regulatory compliance and reducing the risk of fraudulent use.

◆ What is an MVNO Service? An MVNO (Mobile Virtual Network Operator) is a service provider that leases mobile network lines from major carriers (MNOs) and offers communication services under its own brand. Without owning physical network infrastructure, MVNOs can offer low-cost SIM cards and affordable plans by minimizing capital and operational expenses.

Key Factors in Adoption

From Kintetsu Cable Network Co., Ltd.:

'We selected Showcase's 'ProTech ID Checker' considering the balance between pay-as-you-go and monthly fees, as we were evaluating vendors for small-scale operations of around 50 cases per month. Additionally, the fully automated data matching between My Number Card information and subscriber data using AI, which helps reduce data discrepancies in advance, was a key factor in our decision.'

Showcase will continue to support businesses in strengthening security and improving operational efficiency through 'ProTech ID Checker', contributing to the advancement of safe and secure digital transactions.
