Nulliti vs Tokenization
Tokenization protects the number. Nulliti proves the person.
These are not competitors. Tokenization keeps the card number out of harm's way. Nulliti attaches cryptographic proof that the real cardholder authorized the charge. One secures the credential; the other secures the intent. Run both.
Different problems
A safe card number is not the same as a proven cardholder
Tokenization answers "is this card data safe from theft?" It replaces the PAN with a token so card data never has to live in the merchant environment. That is real and valuable - but a token confirms a card was used, not that the cardholder consented. Nulliti answers the second question: it produces a biometric cryptogram bound to a specific cardholder, device, and transaction - the evidence that wins disputes.
Side by side
Tokenization vs Nulliti
Tokenization removes the card data. Nulliti removes the doubt about who authorized.
| Dimension | TokenizationProtects the card number | NullitiBiometric-bound proof layer |
|---|---|---|
| What it secures | The card number. The PAN is replaced by a token, so card data never lives in the merchant environment. | The authorization itself. Nulliti binds the card to the person and proves it on every transaction. |
| What it proves at the point of payment | That a card was used. Not that the cardholder consented. | That the cardholder bound to that card approved this specific transaction. |
| Friendly fraud | Not addressed. A token confirms the credential, not the intent behind it. | Addressed at the root. Signed proof of consent is the evidence that ends "he said, she said" disputes. |
| What survives after authorization | A token reference. Nothing about who authorized the payment. | A signed, timestamped record that carries into the dispute, into representment, and into audit. |
| Where it works | Wherever your token provider reaches. | Any card, any device, any OS. One enrollment covers every merchant in the Nulliti network. |
Additive, not competing
Better together
Because card data is handled by the token provider and never stored in the merchant environment, PCI DSS scope is substantially reduced. Nulliti sits on top of that - a thin proof layer that adds provable, biometric-bound cardholder intent to the tokenized payment you already run. Network-tokenized payments also carry a Visa-documented 4% improvement in approval rates and a 10-basis-point reduction in interchange; Nulliti adds the dispute-winning evidence tokenization was never built to provide.
- Keep your existing token provider - Nulliti works with any of them.
- Reduced PCI scope from tokenization stays intact.
- Add irrefutable proof of intent per transaction.
- Defeat friendly fraud that a token alone cannot address.
