What Prson does

Trust people online, without oversharing.

Free for people to verify, sign in and share. Businesses pay per verification. Only verified answers are charged. See business plans

Use cases

Before you pay or meet, ask.

A challenge is one sentence. The answer is a live photo or video you can trust.

Meeting someone online

Challenge“Hold up three fingers and say today's word.”

A real person, right now. Not a stolen selfie or an AI face.

Buying a used car

Challenge“Walk around the car, show the VIN and odometer.”

Ask before you send a deposit. The seller has to film it themselves.

Renting a home

Challenge“Open the front door and pan across the living room.”

Fake listings fall apart when the landlord has to be there.

Marketplace items

Challenge“Power on the laptop and show the serial number.”

This exact item, in their hands, today.

Hiring a pro

Challenge“Show your workshop and the tool you'll use.”

Know who's coming before they come.

Anything else

If they can show it on camera, you can ask for it. Add a twist, like today's word, and it's hard to fake.

How it works

Three steps. Two minutes.

  1. Ask

    Write one sentence or pick a template. Choose a deadline. Send the link by WhatsApp, email or wherever you found the listing.

  2. They prove it, live

    They open the link in the free Prson app and film it on the spot. Location and motion are recorded and signed with the media.

  3. You check it

    Open the proof in any browser. Every check is spelled out, and the signature is verified on your screen. Keep it as a signed PDF.

  • Filmed in the Prson cameraUploads and screenshots can't be used.
  • Signed on the phoneAny edit breaks the signature.
  • Real IDs, read by NFCPassport and ID chips, not photos of them.
  • Checkable without usSignatures verify in your browser.

Verified identity

Share the fact, not the document.

Verify once with your passport or ID card chip. Then prove you're over 18, a real person, or an EU citizen with a link or QR code, without handing over a copy of your passport.

  • You pick exactly what each person sees
  • Every fact is signed, so it can't be edited
  • Links expire, and you can revoke them

Where Prson can verify you

Verified in 133 countries

Passports from 133 countries, and national ID cards across the EU. Your phone reads the document's chip; Prson checks the issuing country's signature.

World map of the documents Prson can verifyCountries are shaded by coverage: passport and national ID card, passport only, passport with the ID card not yet confirmed, or not yet covered. Use the country search below the map for the same information as text.

Your country: Pick your country to see which of its documents Prson can verify.

  • Passport and national ID card
  • Passport only (no chipped national ID card)
  • Passport; ID card not yet confirmed
  • Not yet covered
How we count countries

Prson also checks that the chip itself is genuine, not a copy: with Active Authentication, or with Chip Authentication run by Prson's server (as Germany's ID card uses). A chip that can do neither counts one level lower.

  • "Not yet confirmed" means we haven't checked whether that country's ID card has a chip Prson can read. We never count it until we have.
  • Small states are shown as dots. Hong Kong and Macao are covered through China's signing certificates.
  • The trust list also holds the laissez-passer signers of the EU and the UN; they aren't counted as countries.

Private sign-in

No email. No password.
Still in the loop.

Sign in with your face or fingerprint on websites that offer Sign in with Prson. If you want their news, it reaches you in Prson, not by email.

  • Each site gets its own ID for you, never your email
  • One feed per site: mute it, turn it off or remove it
  • Your sign-in history stays on your phone

Document signatures

Sign with your verified name, from anywhere.

Read your passport or ID card chip once. Then sign PDFs in a few taps with the legal name on that chip: no printing, no scanning, no account with each company.

  • Passports from 133 countries, and EU ID cards
  • Anyone can check it at app.prson.net/check, or in Adobe Acrobat once they trust our certificate
  • You see every page before you sign someone else's document

An advanced electronic signature under the EU's eIDAS rules, not a qualified one.

Privacy and safety

Your details stay yours.

Prove what's needed and nothing more. Your passport photo and your face never leave your phone, and a fake site gets nothing it can reuse.

  • Your passport stays on your phone

    The chip's photo and your face never leave your phone. We keep a one-way code (a hash) of your details, not your name, birth date or document number.

  • Prove it without the details

    Show you are over 18 and the site sees "yes", not your birth date. The same goes for your country, or being a real, verified person.

  • A different you on every site

    Each website gets its own key and ID for you, so sites can't compare notes. We don't keep a list of where you sign in, only the sites you allow to send you news.

  • Warned before fake sites

    Prson checks every address before you sign in, and each sign-in only works on the site that asked. A fake site can't reuse it.

  • Shares only your recipient can open

    What you share is stored encrypted, and the key travels only inside your link. Links expire, and you can revoke them.

  • No ads, no trackers

    No advertising and no analytics in the app. Crash reports are off unless you turn them on.

Questions

Questions, answered.

Can't someone just film a screen or an AI video?

The answer is filmed in the Prson camera, with the phone's motion recorded at the same time. A video of a screen doesn't move like the real scene, and the phone itself is attested by Apple or Google.

Does the other person need the app?

To answer, yes. It's free on iPhone and Android. You ask from the app too. To view a proof, a browser is enough.

What does Prson keep about me?

Your passport photo and your face stay on your phone. Your name, birth date and document number are checked once, then we keep only one-way codes of them, not the values. When you sign a PDF, the certificate carries the name from your chip. We do keep what's needed to run the service: proofs until they expire, your email if you give us one for recovery, and your device's push token.

Is a Prson signature legally valid?

It's an advanced electronic signature under the EU's eIDAS rules: tied to the name on your passport chip, made on your phone, and any change to the PDF breaks it. It isn't a qualified signature, so documents that legally require one (some property or notarial deeds, for example) still need a qualified provider.

Do websites get my email?

Only if you choose to share it. A website that wants to send you news asks when you sign in; its updates then reach you in the Prson app, and you can mute it, turn it off or remove it at any time.

Is it free?

Yes, to verify yourself, share facts, sign in and answer challenges. Asking for proof is free once a day; more uses credits. Businesses pay per verification from a prepaid balance (from 0.25 at launch prices, until 31 March 2027), and only for verified answers.
