PAY Service

PAY Service

PAY Service was founded in 2019 as a subsidiary of Hit Ltd. and established in Nihonbashi, Tokyo, to serve as the exclusive Japanese launch partner for PAX Technology's point-of-sale products. President Naruhiko Okada took leadership in 2020 and immediately secured a landmark deployment of the PAX A620 terminal into a major Japanese telecommunications carrier, quickly following that with a large-scale rollout of the A920J model to a big-box retailer. Okada also built out what the firm claims was Japan's first P2PE-certified key-injection infrastructure, giving PAY Service the cryptographic factory capability that became the substrate for its later software ambitions. The firm now operates a three-layer technology stack: a distribution and maintenance business for the full PAX Android-based terminal lineup — including the dual-display A8700 and the flagship Android POS models — a proprietary remote estate-management cloud service branded MAXSTORE, and an in-house payment-application development practice that integrates credit, e-money, QR, private-label house money, and loyalty-point settlement into single-binary Android apps. Confirmed deployments span big-box retail, regional banks for PIN-verification applications, and transit-operating companies. The geographic concentration remains entirely domestic, though the reliance on mainland Chinese hardware supply via PAX Technology creates a structurally cross-border procurement relationship. Team size is undisclosed. In February 2026 the firm recapitalized to ¥30 million and transitioned from a Hit Ltd. subsidiary to an independent group company, a governance shift announced alongside its fourth consecutive PAX Technology award — the "Preferred Award" for 2026. Key milestones over the past two years include the 2024 achievement of ISO 27001, 9001, and 14001 certifications; the relocation of its headquarters to Kojimachi, Chiyoda-ku; and the first shipment of the PAX A8700 dual-display terminal, which positions the firm to serve full-service checkout-counter environments rather than just the payment-capture layer. Structurally, PAY Service operates as a payments-platform integrator that owns the full implementation chain — key-loading, terminal remote management, and application-layer UX — for a hardware platform it does not manufacture. That architecture makes it the engineering intermediary between a Chinese hardware OEM and Japanese acquiring banks, retailers, and transit operators, a position that requires it to reconcile PAX Technology's global Android roadmap with Japan's specific EMV, Felica, and QR-code settlement environments without ceding the merchant-facing application logic to the terminal vendor.
