Who we are

私たちは国家戦略として推進されているキャッシュレス化の一端を担い、決済ビジネスへの豊富な知見とテクノロジーを活用し、主に加盟店向けのソリューションを開発・提供しています。

【決済×エンタープライズ×ブルーオーシャンで存在感を発揮する】

  • 自社プロダクトを展開 当社はキャッシュレスを導入する加盟店と決済事業者(カード会社等)を接続するために必要な決済アプリ・決済端末・決済センターまでをワンストップで提供する自社サービスを展開しています。 黒子として皆さんが街中で利用するキャッシュレス決済を支えており、当社の稼働端末台数は約16万台、年間5000万回以上の取引が行われています。
  • 圧倒的な決済知見とプロダクト力で、エンタープライズマーケットで高い評価を受ける キャッシュレスを取り巻く法律やセキュリティは非常に複雑ですが、当社はキャッシュレスが広く普及する前の2011年の創業から10年以上にわたり事業を展開し、他社を圧倒する決済業務知見を保持していることが大きな強みです。 また、大手企業はカスタマイズ要望が強く自社プロダクトの導入は困難と言われていますが、培ったノウハウを自社プロダクトに還元し高い標準力を持つことでエンタープライズ領域への導入を実現している業界内でも珍しい立ち位置を築いています。 結果いち企業あたり数千〜数万台の導入を頂いています
  • ブルーオーシャン領域をターゲットにし、他社にはない機能で存在感を高める 自社プロダクトは生命保険や損害保険、フィットネス、各種スクール、モビリティ業界を中心に拡大しており、キャッシュレス化が進みきっていないブルーオーシャンの業界をターゲットにし、この自社プロダクトでしか実現できない特異な機能を保持しております。 例えば、塾やフィットネスクラブでの入会処理時にクレカやキャッシュカードを当社の小型端末で読み取るだけで本人認証を行って登録し、毎月のご利用料金を自動的に引き落とすことができるリカーリング機能は、業界で唯一当社のみが提供できる機能です。 他にも、小型×無人市場に向けた国内初の取り組みとして世界第3位の決済端末ベンダーと協業し、手のひらサイズに小型化された決済端末を用いたセルフオーダー決済の提供を実現しようとしています。 さらに先の未来では決済端末自体がソフトウェア化されていくと考えられており、店舗をはじめとする対面での決済にとどまらない非対面向けのシステム提供を視野にいれた展開を予定しています
  • 私たちはグループとして日本を変えていく 「決済から、きのうの不可能を可能にする。」をミッションに、あらゆる産業とサービスにFintechを組み込んでいくプロジェクトを進める企業のグループ会社です。 オリジナルPayをスピーディに構築できる自社プロダクトは大手小売流通業者への導入実績を誇り、2024年4月には総額19億円の資金調達を実現しIPOにむけて更なる成長を目指しています。

We are the company who plays a vital role in the national strategy of promoting cashless transactions by leveraging extensive knowledge and technology in payment business, primarily developing and offering solutions for member merchants.

[Demonstrating Presence in Payments, Enterprise, and Blue Ocean]

Developing Our Own Product We provide a one-stop service which connects cashless merchants with payment providers (such as card companies) by offering the necessary payment applications, terminals, and centers. Acting as a behind-the-scenes supporter, we facilitate cashless payments used in everyday settings, with around 160,000 operating terminals and over 50 million transactions processed annually.

High Evaluation in the Enterprise Market with Unmatched Payment Expertise and Product Power The regulations and security surrounding cashless payments are quite complex. However, since our establishment in 2011, prior to the widespread adoption of cashless systems, we have developed significant expertise in payment operations, which is a major strength. Large enterprises often have strong customization demands, making the introduction of their own products challenging. Yet, by leveraging our accumulated know-how, we have built a unique position in the industry that enables us to maintain high standards for implementation in the enterprise sector. As a result, we have seen implementations ranging from several thousand to tens of thousands of units per company.

Targeting Blue Ocean Areas to Enhance Our Presence with Unique Features Our own product is expanding primarily in industries such as life insurance, property insurance, fitness, various schools, and mobility, focusing on blue ocean sectors where cashless adoption is still evolving. We possess unique features that can only be realized with this product. For example, when enrolling in a tutoring service or fitness club, our compact terminals can read credit or cash cards for identity verification and automatically withdraw monthly feesa function uniquely provided by us in the industry. Additionally, as a pioneering initiative in the small and unmanned market, we are collaborating with the world's third-largest payment terminal vendor, to offer self-order payment solutions using palm-sized terminals. Looking further ahead, we anticipate that payment terminals will evolve into software solutions, allowing for non-face-to-face systems beyond in-person payments.

Changing Japan With the mission of "Making the impossible possible from payments," as we are a part of a group company, which integrates Fintech into various industries and services. Our proprietary product enables rapid construction of original payment solutions and has successfully been implemented with major clients and leading retail distributors. In April 2024, we achieved fundraising of 1.9 billion yen and are aiming for further growth toward an IPO.
