How to Scan Documents for KYC Verification

This guide shows you exactly which pages to capture, how to scan them properly, and how to keep sensitive documents safe while you submit them.

One important note before you start: every bank, mobile network, and exchange runs its own checklist. Use this guide for the scanning part, and always follow the exact document list your provider shows you — if it asks for a specific document, send that one, not a substitute.

What KYC usually asks for

KYC stands for "Know Your Customer" — the identity checks financial services must run before they open your account. Most providers ask for two things:

• Proof of identity: a government photo ID — national identity card, passport, or driving licence.
• Proof of address: a recent utility bill, bank statement, or official letter showing your name and current address.
• Sometimes a selfie or live photo: holding your ID, or a short video check, so the provider can match your face to the document.

Some providers also ask for a second document if the first one is unclear, or for a tax number on exchanges and investment platforms. Gather everything before you start scanning so you can submit in one session.

Step 1: Capture the right pages

Scan the pages the verifier actually needs — no more, no less:

1. National identity card: scan the front and the back. The back often carries the address, issue date, or machine-readable zone the verifier checks.
2. Passport: scan the photo page only, unless the provider explicitly asks for visa or stamp pages too.
3. Driving licence: scan front and back, as the address and expiry details are usually split across both sides.
4. Proof of address: scan the full first page of the bill or statement — the part showing your name, address, and the issue date. Do not crop off the date; an undated document is a common rejection reason.

If a document is double-sided, never submit just the front and hope. A missing back page is one of the most common reasons KYC uploads get rejected.

Step 2: Get a clean, legible scan

Verifiers — human reviewers and automated checks alike — reject scans they cannot read. Get it right at capture time:

• Flat and fully visible: lay the document on a plain, dark surface and capture the whole page, including all four corners. Nothing important should be cut off at the edges.
• Good, even light: scan near a window in daylight, or under a bright room light. Avoid shadows from your phone and glare on laminated cards — tilt slightly if a reflection washes out the photo.
• Sharp text: hold the phone steady and check the scan before moving on. Names, numbers, and expiry dates must be readable when you zoom in.
• Colour, not black-and-white: submit colour scans. Security features, stamps, and photos are part of what the verifier checks, and greyscale can hide them.

Scanning in your browser works well here: capture, straighten, and export as a PDF without installing an app — and because processing happens on your device, your ID never uploads to a scanner company's server.

Step 3: Name and organise the files

Clear filenames help you — and the reviewer — keep track of what is what:

• Use plain names: ID-front.pdf, ID-back.pdf, proof-of-address.pdf. Avoid camera defaults like IMG_4821.jpg.
• One document per file unless the portal asks for a combined upload. Merging your ID and your bill into one file confuses automated checks.
• Keep the originals: save the clean scans in a folder on your device before uploading, so a rejected submission costs you a re-upload, not a re-scan.
• Check the file size: if a portal caps uploads, a standard scan exported as PDF is usually well under the limit; avoid sending huge raw photos.

Step 4: Submit safely

KYC documents are the most sensitive files most people ever upload, so treat the submission step seriously:

• Upload only through the official app or website of your bank, network, or exchange — never through a link in an unsolicited message or email asking you to "verify urgently."
• Use your own device and connection where possible, not a shared or public computer, for the upload itself.
• Delete stray copies: after a successful submission, remove duplicate scans from your downloads folder and messaging apps so the document does not live in places you forgot about.
• Never send KYC documents over chat or social media to someone claiming to be support staff. Legitimate providers collect them through their own secure upload flow.

If a submission is rejected, read the reason before re-uploading. Re-sending the same blurry scan will be rejected again; fix the specific problem — a cut-off corner, a missing back page, an expired document — and then resubmit.

Common KYC scan rejections (and the fix)

• Blurry or dark photo: rescan in better light, hold steady, and zoom in to check the text before submitting.
• Corners or edges cut off: pull back so the full document is in frame, then crop to the document edges only.
• Only the front submitted: add the back page — most ID checks require both sides.
• Expired document: no scan quality fixes this; use a current document and check the expiry date before you start.
• Name or address mismatch: make sure the proof of address shows the same name and address you registered with, and that the bill is recent enough for the provider's rules.
• Wrong file type: if the portal wants PDF and you sent a photo, export the scan as a PDF first.

Do I need to scan both sides of my ID for KYC?
In most cases, yes. The front carries your photo and number, while the back often carries the address, expiry, or machine-readable details the verifier checks. Submitting only the front is a common rejection reason, so scan both sides unless the provider explicitly says front-only.

Can I use a photo of my ID instead of a scan?
A well-lit, straight, fully visible photo can pass, but a proper scan is safer: perspective correction squares up the document, shadows are cleaned, and the text stays sharp. If your first photo upload is rejected, rescan it properly rather than retaking the same kind of photo.

Is it safe to scan my ID with an online scanner?
It depends on where the processing happens. Scanner.cam processes everything on your device — your ID never uploads to a server. Avoid scanner apps that upload your documents to their cloud, especially for identity documents, and always submit through the provider's own official upload flow.

What proof of address works for KYC?
Typically a recent utility bill, bank statement, or official letter showing your name and current address, including the issue date. Requirements vary by provider and country, so check the exact list your bank, network, or exchange shows you before you scan.

Why was my KYC document rejected?
The usual reasons are blurry or dark images, cut-off corners, a missing back page, an expired document, or a name or address that does not match your registration. Read the rejection reason, fix that specific problem, and resubmit — sending the same file again rarely helps.
