What are World ID Proofs and how do I use them in World ID app?
Introduction to World ID Proofs
A Proof lets you confirm things about yourself to an app without revealing anything else. You claim each Proof in a different way, and once claimed, it's stored on your device.
You can add, view, and manage these Proofs from the Credentials tab in World ID app.
World ID Proofs use zero-knowledge proofs, so you can prove something about yourself, like being over 18, without revealing your identity or other personal information.
Types of Proof
Proof of Human
Proof of Human confirms that you are a unique human. You claim it by verifying in person at an Orb, which provides the highest level of assurance.
Proof of Attributes
This proves specific attributes from your government credentials like age or nationality, without revealing anything else. The following NFC-enabled government ID types are currently supported (where available):
- Passports
- National ID Cards, such as:
- eID (Italy)
- My Number Card (Japan)
NFC (Near Field Communication) is a wireless technology that allows your phone to securely read information from a compatible document held in close proximity. Most modern smartphones support NFC. On Android, NFC must be enabled in your device settings. On iPhone, NFC is always on.
To be eligible, a passport must display the biometric chip symbol (the small rectangular icon with a circle) on its cover:
Proof of Presence
Proof of Presence proves you’re present with just a selfie. The process is privacy-preserving and happens on your mobile device.
How to Claim a World ID Proof
Proof of Human: Claim it by verifying in person at an Orb. See What should I expect when getting my World ID verified at an Orb? for what to bring and what to expect.
Proof of Attributes: Claim it by adding a supported NFC-enabled government ID in World ID app:
- Open the Credentials tab in World ID app.
- Tap the Add verification button.
- Select your government ID type (e.g., Passport or National ID).
- Follow the on-screen instructions to scan your document's NFC chip.
- Once verified, it will appear in the Credentials tab.
Proof of Presence: Claim it with a selfie in World ID app, where available.
Expired Proofs
Proof of Human: you may occasionally be asked to renew and update your World ID at an Orb. See Why do I need to update my World ID?
Proof of Attributes: if the government ID behind it has expired, it will be flagged in the Credentials tab. Claim a new Proof of Attributes using a valid, unexpired document.

I’m having issues verifying my passport, national ID, or My Number Card.
If you're having trouble verifying your passport, country's national ID, or My Number Card to claim a Proof of Attributes, please try the following troubleshooting steps:
General Checks
- Make sure that you’re scanning a physical passport, national ID, or My Number Card.
- Verify that the ID is yours and that it has not expired.
- Confirm that the ID is NFC chip-enabled. For passports, look for the NFC symbol on the cover, which looks like this:
.
- NFC (Near Field Communication) is a wireless technology that allows your phone to read information from a compatible card, device, or document located in close proximity — for example, when you tap your phone on your passport during verification. Most modern smartphones have NFC built in, and it needs to be turned on in your phone’s settings.
- If you're using a My Number Card (Japan only):
- Ensure the card is active and not locked or damaged.
- Make sure you entered the correct date of birth, expiry date, and 4-digit number.
Illumination and Scanning Environment
- Use an area with good lighting and make sure the ID is clear and in focus.
- Remove any phone case or document sleeve that might interfere with NFC scanning.
- Place the ID on a flat and steady surface if possible, and hold your phone steadily above it.
Adjust Your Scanning Technique
- Make sure your phone’s screen is facing up when you tap it on the ID.
- Lift your phone up and try to tap it on the ID again (instead of just sliding it up and down).
- For passports:
- Try different positions. Depending on the country and document type (passport back cover, front cover, photo page), the NFC chip location may vary.
- Due to extra shielding on some passport covers, the chip may be difficult to scan from the outside. If your passport has the chip on its front cover, open the passport and try to scan it from the inside.
- Position your phone perpendicular to your passport (sideways on top of the passport) for optimal scanning.
Additional Steps if Scanning Still Fails
- Check if your device supports NFC scanning and that NFC is enabled (on Android, check settings; on iPhone it’s always on).
- Update your World Money app or World ID app to the latest version.
- Force-close and reopen the app.
- If you're using a My Number Card (Japan only):
- If the date of birth, expiry date or 4-digit PIN you entered does not match the card’s chip data, you’ll see an error. Use the “Go Back” option to correct and retry.
- If the card has become locked due to too many failed attempts, you must visit your local municipal office to reset the card before attempting verification again.

How do I sign up for World ID?
To sign up for World ID, follow these three steps:
Step 1: Download the World Money app from the App Store or Google Play and create an account if you don't have one yet.
-
Open the app and tap I am a new user on the welcome screen.
-
Review the Terms and Conditions and TFH Privacy Notice, then tap Accept to continue.
-
The app will display a Getting ready screen while your account is being set up — this may take a few seconds.
-
If your device supports passkeys, you'll be prompted to save a passkey for secure, passwordless sign-in across your devices. Tap Continue to save, or Save on Another Device to store it elsewhere..
- Once your account is created, you'll see a Account created (Welcome to World ID) confirmation screen.
Step 2: Tap your profile icon to open Settings and select World ID (Identity app).
Step 3: If you are prompted, download the World ID app.
If you already use World Money, you don’t need to create a new account to use World ID app. Sign in with your existing account, and your World ID Proofs and account login details will carry over automatically.
Step 4: Open World ID app and go to the Credentials tab. Choose how you'd like to claim a World ID Proof:
- Verify at an Orb: Tap Get verified and follow the prompts to find a nearby Orb and claim Proof of Human. Proof of Human proves you’re a unique human and provides World ID’s highest level of assurance.
- Add a supported government ID: Tap Add Credential and follow the prompts to scan an NFC-enabled passport, national ID, or My Number Card with your phone. This lets you claim Proof of Attributes, where available.
Step 5: Once your Proof is claimed, World ID is ready to use. You can use your World ID Proofs across participating apps without revealing unnecessary personal information.
You don’t have to choose only one. If there’s no Orb near you yet, you can add a supported government ID now and verify at an Orb later. Check World ID app regularly for Orb availability near you.
What World ID Proofs let you do
Signing up creates your account. Claiming World ID Proofs lets you prove specific things about yourself to apps without sharing the underlying information. World ID offers three Proofs:
- Proof of Human proves you’re a unique human. It’s the highest level of assurance, backed by the Orb.
- Proof of Attributes proves specific attributes from your government credentials like age or nationality, without revealing anything else.
- Proof of Presence proves you're present with just a selfie. The entire process is privacy-preserving and happens on your mobile device.
Websites and apps which integrate World ID decide which World ID Proofs they accept. You can view your Proofs at any time in World ID app.
