Wiki route
This entry sits under payment-firms INDEX (its domain route). Read it against Kyash for peer / contrast (prepaid + app-led fintech), and against the FSA plus the funds-transfer vs prepaid boundary for the supervisory / system boundary.
TL;DR
株式会社スマートバンク is a household-finance / prepaid wallet fintech that operates the household-management prepaid card “B/43 (Bee-yon-san, renamed to “ワンバンク”)”. In public information it has the rare configuration of holding two licenses —— a funds-transfer service provider (Director-General of the Kanto Local Finance Bureau 第00084号) and a third-party-type prepaid payment instrument issuer obtained in 2024 年 (Director-General of the Kanto Local Finance Bureau 第00782号). It pairs a chargeable Visa prepaid card with a household-account-book app, a case of combining a payment account with a household-management UX.

2. Operating model
SmartBank builds a payment / account-like UX from the problem of household budget management. It uses the licensing of both prepaid and funds-transfer business to support the flows of shared spending and the wallet. Although it is small in scale compared with megabanks and telecom-group wallets, in showing a design that launches a financial UX from “household budgeting” rather than from banking・commerce, a contrast with the Kyash or PayPay super-app is useful.

3. Why this page matters
- It fixes a concrete example of a license configuration where a single company holds both funds-transfer business and third-party-type prepaid payment instruments.
- It makes visible the design of combining “prepaid (refunds prohibited in principle)” and “funds-transfer (remittance possible)” within a single company.
- It becomes a case anchor for an independent fintech building a payment account with household management as the entry point.
