Cryptnox Wallet identity verification combines document capture, an optional ePassport NFC read, a selfie liveness check, and a digital signature created with a blockchain key held by your Cryptnox card. The blockchain address you select identifies which key produced the signature — your private key stays on the card throughout.
Open Identity in Cryptnox Wallet
On the Portfolio screen, tap Tools in the bottom bar. A short menu opens — tap Identity.
Start your identity verification
The welcome screen lists the four things that will happen: you capture your photo ID, take a selfie, sign with your Cryptnox card, and submit the verification for processing.
Tap Get Started. Exit returns you to your portfolio without starting.
Enter your email address
Type an address you can actually open. It's associated with your verification and is how you'll be contacted about it.
Tap Continue.
Scan your passport or identity document
Lay the document flat and open at the photo page, on a plain surface in even light. Hold the phone above it so the page fills the frame, with all four edges inside.
Auto Capture takes the picture as soon as the page is steady and in focus. Manual waits for you to tap the shutter — use it if auto capture keeps missing.
Review and confirm your details
Cryptnox Wallet reads the details off the document and pre-fills the form — first and last name, document number, date of birth, expiry date, document type, gender, nationality and issuing country. Go through them and correct anything that was read wrong.
Nationality and issuing country are optional. Tap Continue.
Verify the ePassport chip
Optional but recommendedMany modern passports carry an NFC chip containing cryptographically protected document and biometric information. Reading it is one of the strongest checks the flow can make — it isn't guaranteed to be present on every ID card.
Tap Scan Passport, then hold the phone flat against the passport cover and keep both still while the chip is read. The step can be skipped, and not every ID card contains a readable chip.
| Without chip verification | With successful chip verification |
|---|---|
| Document image and extracted details | Additional cryptographic document checks |
| Verification can continue | Enhanced document authenticity evidence |
When the read succeeds you'll see Document Verified, the photo stored on the chip, and which security checks passed. Tap Continue.
Complete the selfie and liveness check
Hold the phone at eye level, in even light, and fit your face inside the oval. Slowly turn your head as instructed, returning to centre between movements.
Choose the blockchain key that will sign your verification
Your card holds several blockchain keys — Bitcoin SegWit, Ethereum, TRON or XRP. Pick the one that should sign your verification.
If you have no preference, Ethereum is a sensible default. Tap Continue.
Sign with your Cryptnox card
Tap Start Scanning, then hold your card flat against the back of your phone, over the NFC area. Keep it still while the signature is created.
The wallet shows Card Connected and then Signing…. If it drops out, hold the card again and let it retry.
Review and submit your verification
The review screen shows everything before it's sent: the document image, your confirmed details, the biometric and liveness results, document security checks, the selected blockchain address, and the digital signature.
Read it through, then tap Submit KYC Data.
Verification submitted
Verification Submitted confirms the submission has been sent and signed with your Cryptnox card's selected key.
Tap Done to return to your portfolio. If a submission is rejected instead, the wallet explains why — the most common reasons are covered below.
Troubleshooting Cryptnox Wallet identity verification
If something goes wrong along the way, here's how to fix it.
"Verification Incomplete" after the chip read
The chip answered, but not every security check passed. You can carry on — the remaining checks are completed after you submit. Or tap Rescan and try again with the passport out of its cover and lying flat.
The passport chip cannot be read
Remove the passport from its cover, take off any phone case or metal accessory that could interfere with NFC, and move the phone slowly across the back cover to locate the chip. Keep the phone still once communication begins.
My document will not scan
Add light, reduce glare, and make sure all four edges of the page are inside the frame. If Auto Capture keeps missing, switch to Manual and tap the shutter yourself.
The liveness check does not complete
Turn your head further and more slowly, and return to the centre between the two turns. Keep your whole face inside the oval, eyes open, and avoid strong backlighting.
My Cryptnox card is not recognised
The card has to be added to the wallet before it can sign: Settings → Cards. Then start the Identity flow again.
The camera remains black
Camera access is required. Allow it when the phone asks, or if you refused earlier, turn it on in your phone's app permission settings for Cryptnox Wallet.
