Disposable virtual cards backed by true quantum entropy. We're finalizing our card issuer partnership — join the waitlist to be first when we open access.
Three steps to quantum-secured payments. No hardware required.
Request a new virtual card. quantum entropy generates true random entropy — your card number is derived from quantum superposition states.
Every transaction is signed with a unique quantum nonce and HMAC-SHA256. Cryptographic proof links each payment to its quantum entropy source.
Use your quantum card anywhere Visa is accepted. Set spend limits, lock to merchants, or generate single-use cards that self-destruct after one transaction.
Why quantum entropy matters for your financial security.
Traditional card generators use pseudo-random number generators (PRNGs) — deterministic algorithms that can theoretically be predicted. Our cards use true quantum randomness from quantum entropy, making prediction mathematically impossible.
Every transaction receives a fresh quantum nonce and is signed with HMAC-SHA256. Each payment carries cryptographic proof of authenticity that can be independently verified — creating an immutable audit trail.
Single-use cards eliminate recurring charge fraud. Merchant-locked cards prevent unauthorized category spending. Quantum entropy proofs provide cryptographic evidence for dispute resolution.
Quantum Card is in private development. We're finalizing our card-issuing partnership and onboarding a small group of design partners. Join the waitlist to be notified when we open public access — no payment required.
