# Atomic Money

> The payments umbrella for Sumvin — ramps and banking, card issuing, and payment links with x402 acceptance.

Atomic Money is the home for everything that moves money on Sumvin. It covers three surfaces: getting funds in and out (**ramps and banking**), spending them on a card (**card issuing**), and getting paid (**payment links and x402 acceptance**). Each surface has its own pages below — this page is the map.

## The three surfaces

<CardGroup cols={2}>
  <Card title="Ramps & banking" icon="arrow-right-arrow-left" href="/products/ramps/overview">
    On-ramp and off-ramp, plus bank linking — move funds between fiat and crypto, and connect a user's bank account.
  </Card>

  <Card title="Cards — your Sigil on Visa" icon="credit-card" href="/products/card-issuing/overview">
    Issue a card backed by a user's identity, with a funding wallet and a card record you manage through the API.
  </Card>

  <Card title="Payment links & x402" icon="link" href="/products/payment-links/payment-request-links">
    Shareable payment request links that any x402-capable wallet, agent, or browser can settle.
  </Card>
</CardGroup>
