Jamm

Jamm provides an online payment solution that enables direct payments from bank accounts without requiring credit cards. Designed to offer clarity and simplicity to both users and merchants, the platform addresses the needs of individuals who prefer or require alternatives to credit card payments. By supporting transactions directly from bank accounts, Jamm helps merchants capture users who might otherwise be unable or unwilling to pay with credit cards.

The service is compatible with over 300 banks across Japan, including major institutions such as Sumitomo Mitsui Banking Corporation, MUFG Bank, and Mizuho Bank. Merchants can implement Jamm through two main integration methods: an API/SDK for custom development, which can be completed in as little as two weeks and is supported by Jamm engineers via Slack, or a no-code option where user withdrawals are managed via CSV and payment links are generated from a dashboard, requiring no development effort. For users, payments can be made for one-time purchases or subscriptions by selecting Jamm as a payment method on supported apps or websites, followed by a simple approval process.

The platform also holds ISO certification, underscoring its commitment to providing a secure payment environment.
