a $1,000 token, two Java cards, backed by the reserve
Demo · virtual cards
CoinCard anchors the value at the edges only: it issues a reserved $1,000 token and redeems it.
The transfer in the middle is card-to-card — nothing moves on a ledger, and no holder identity is recorded.
Whoever holds the card holds the value. Only CoinCard cards are accepted.

Peer-to-peer cash
Card-to-card = VERIFY_PIN → PERMIT_TRANSFER → INIT_SESSION → EXTRACT_TOKEN (sender) → DEPOSIT_TOKEN (receiver) → CONFIRM_DELIVERY (sender). No service call — this is the off-ledger move. Cash out calls CoinCard to redeem from the reserve.
