What virtual cards solve

Cloud platforms, advertising networks, developer tools and global SaaS products often require international card payments. Virtual cards connect wallet funding, card issuing, card top-ups, transaction notifications and reconciliation into one operational flow.

Core capabilities

OPEN RAMBO virtual cards are designed for compliant software subscriptions and digital service spend, with wallet balance, USDT funding, card applications, card top-ups, freeze, unfreeze, close, transaction lookup and funding history.

Implementation notes

In production, BINs, card types, opening fees, top-up rates, refund fees and decline rules should live in database configuration rather than hard-coded source. Every card operation should keep an internal order id, upstream id, balance snapshot and compensation record.

Live product resources
Card products, fees, funding options and limits can change. Use the authenticated card workspace and issuing API documentation as the source of truth.
