Deone Card

Deone's Tokenized Card, Explained

No printed card number, no CVV, no expiry date. Deone's card carries an encrypted token instead. Here's what that actually means, what the certifications behind it mean, and what it doesn't protect you from.

How It Works

Device tokenization, not a card number in your pocket

A standard card carries your real account number (PAN), CVV, and expiry date printed on the plastic and stored in the chip: static data that stays valid until the card is reissued. Deone's card doesn't. When a Deone card is issued, a device tokenization service generates a device-specific token tied to that one physical chip. The token is embedded in the NFC chip during setup inside the Deone App. Nothing on the card's surface identifies the underlying account.

  • No PAN, CVV, or expiry printed on the card or exposed in the chip

  • The token only works for that specific device, so it has no value if intercepted and used elsewhere

  • Every tap generates a one-time transaction cryptogram through the EMV contactless protocol. The code can't be replayed or reused

  • The NFC antenna only responds within roughly 3cm, which limits ambient or relay-style reading attempts

It's the same idea behind tokenized mobile-wallet payments like Apple Pay and Google Pay: a device-bound token standing in for the real card number, just applied to a physical card instead of a phone.

Certifications Explained

What the badges on the card actually mean

Deone's card materials cite three certifications. None of them are Deone-specific. They're independent chip and payment-industry standards, which is exactly why they're worth checking rather than taking on faith.

CertificationWhat It MeansEveryday Analogy
CC EAL5+Common Criteria Evaluation Assurance Level 5+, an internationally recognized hardware security rating. The secure element inside the chip is built on Infineon's SECORA Pay platform, an existing, independently verifiable Infineon product line (confirmed on Infineon's own site) certified to CC EAL5+ with EMVCo compliance.The same assurance level used in passport chips and SIM cards. It rates the hardware itself, not Deone's app or backend.
PCI DSSPayment Card Industry Data Security Standard: the baseline standard for any system handling card data. Deone's materials cite this compliance for 'the tokenization platform' without naming which of its legal entities is the actual PCI DSS-compliant processor. See the operating structure on the Deone overview page for the full entity breakdown.Table-stakes for any payment processor; being compliant doesn't mean a system is unhackable, just that it meets minimum industry security requirements.
PCI-CPPCI Card Production standard: governs the physical and logistical security of how cards are manufactured and personalized, not just the software.Covers the factory and supply chain, not the app.

Certifications describe the hardware and manufacturing process. They don't independently verify Deone's own app, backend, or account-recovery security. None of that is covered by CC EAL5+, PCI DSS, or PCI-CP.

Materials by Tier

Same tokenization, different card

Every tier uses the same tokenized chip architecture. What changes tier to tier is the physical card: material, construction, and whether a second device ships alongside it.

Deone card materials by tier: plastic Deluxe, full-metal Prestige, ceramic-metal Executive
TierMaterialConstructionExtra Device
Deluxe SuitePlastic (green)Standard card-body injection moldingNone
Prestige SuiteFull metal (brushed stainless-steel style)Metal card body with embedded chip and antennaNone
Executive SuiteCeramic-metal composite, ~22 gramsPrecision CNC-machined and laser-engraved; ceramic-metal composite is the same class of material used in high-end watch bezels, harder than stainless steel and more resistant to scratching and wear. Integrating an EMV chip and contactless antenna into a ceramic-metal body is a more complex manufacturing process than standard plastic or metal cards.Payment Bracelet: a wearable version of the same tokenized chip, in a woven-cord band

The Honest Limit

What tokenization doesn't protect against

Tokenization protects card data at rest and in transit. The token itself is close to worthless if intercepted. It does not change what happens once a transaction is authorized, or what happens if someone gets into your account another way. Deone's own materials draw a sharp distinction here that's worth taking seriously: a traditional bank can step in. It can freeze a suspicious transaction, or reverse a fraudulent charge after the fact, and it can do that days later, not just in the moment. Deone's card is connected to a non-custodial onchain account. Deone states no institution can freeze or reverse a transaction on your behalf. That's the trade-off of full custody, and it cuts both ways.

  • A tokenized chip doesn't stop phishing, social engineering, or someone getting your app credentials directly

  • Deone's materials describe onchain transactions as irreversible, so there's no chargeback-style safety net once a transaction clears

  • Tokenization secures the card's data channel, not your recovery phrase, PIN, or device passcode. Those remain the actual attack surface

  • The certifications above rate the chip and manufacturing process; see the caveat above for what they don't cover

This is a structural description based on Deone's own materials, not a security audit. DeoFin has not independently tested Deone's tokenization implementation.

If You Lose It

Losing your card vs. losing your Payment Bracelet

Deone's materials only spell out a specific loss-recovery flow for the Payment Bracelet (Executive tier): lose it, and blocking it instantly in the Deone App disables the token immediately. Nothing on the physical device can be used or cloned after that. The same public materials don't describe an equivalent step-by-step process for a lost physical card specifically.

  • Payment Bracelet: block-and-disable flow confirmed in Deone's product materials

  • Physical card: no separate lost-card procedure is documented in Deone's public materials. It likely mirrors standard card-blocking via the app, but this isn't confirmed

  • Either way, the token itself carries no value once disabled, since it's tied to that one device

Verify the exact lost-card process directly with Deone before relying on it. This isn't independently confirmed.

Frequently Asked Questions

Deone's card materials reference acceptance through major global payment networks rather than naming a specific network on their public site. What's confirmed is the tokenization architecture itself: a device-bound token replacing the printed card number. For network-specific details, check Deone's official documentation.
Instead of a static card number, CVV, and expiry printed on the card, a device tokenization service issues a token tied to that specific chip. The token is only useful for that device. Intercepting it doesn't give access to the underlying account the way a stolen card number would.
No. CC EAL5+ rates the hardware security of the chip itself. That's the same assurance level used in passport chips and SIM cards. It doesn't cover Deone's app, backend, or account-recovery process, none of which are addressed by this certification.
Material and construction. It's a ceramic-metal composite card, around 22 grams, CNC-machined and laser-engraved, the same class of material used in high-end watch bezels. Deluxe uses plastic, Prestige uses full metal. All three tiers run the same tokenized chip architecture underneath.
The token architecture means a cloned magnetic-stripe-style attack isn't viable. The chip generates a unique cryptogram per transaction and the token itself is device-bound. That said, tokenization doesn't protect against someone who has your app credentials or device passcode; the token is not the only way into the account.
Deone's public materials confirm an instant block-and-disable flow for the Payment Bracelet specifically. An equivalent documented procedure for a lost physical card isn't published. Verify the exact process with Deone directly before assuming it works the same way.
