How to scan an ID card with iPhone: front, back, one clean PDF

A property manager emails at lunch: "Please send a copy of your driver's license, front and back, as one PDF." You have no scanner nearby, so you type "how to scan ID card with iPhone" into a search bar. This guide shows how to scan an ID card on a dark surface, both sides into one PDF, check it and send only what was asked.

Why a clean ID scan matters

A clean ID scan gets your application through on the first try. The person who reads it must check your name, the photo, the expiry date and often a number, and a copy with glare on the date or a cut-off corner comes back with a request to resend. That costs you a day on a rental or a job offer where other people are in line.

A clean scan also protects you. An ID copy carries your full name, date of birth, address and a document number, which is enough for fraud in the wrong hands. When the file is sharp, correctly named and sent once to the right person, you are less likely to send it again to the wrong place.

Two paths: a photo or a scanned PDF

An ID copy reaches the requester in one of two forms. The first is a camera photo: fast, but it keeps the table, the angle, the shadows and the glare, and the front and back become two separate image files. The second is a scan from a document scanner, which finds the card's edges, crops the background, fixes the perspective and saves both sides as one PDF.

The rest of this guide follows the scanner path, and the comparison further down shows where a photo still fits.

How to scan an ID card with iPhone, step by step

Scanning an ID card with iPhone takes about a minute with any document scanner. The steps below use MRS, which has a Scan ID tool; Notes and Files work the same way up to the save step.

1. Put the card on a dark, plain surface. A dark desk, a black notebook cover or a dark T-shirt gives the scanner a strong contrast with the card's light edges. Avoid patterned tablecloths and wood grain, which can confuse the edge detection.
2. Open MRS, go to Tools and tap Scan ID. Scan ID opens Apple's document scanner, the same camera that the Scan document tool uses. It finds the card's edges by itself, captures the page when the picture is steady and fixes the perspective. Pick the color mode at the top of the camera screen so the photo on the card keeps its colors.
3. Scan the front. Hold the iPhone parallel to the card, about a hand's width above it, and wait for the blue frame to settle on the edges. The scanner captures the side automatically; tap the shutter button if it does not.
4. Flip the card and scan the back in the same session. Do not tap Save between the two sides. The front and the back become two pages of the same PDF, front first. MRS does not place both sides on a single page, so if a form asks for that layout, ask the requester whether a two-page PDF works.
5. Check the edges and the glare. Tap the page thumbnail in the corner of the scanner to see each capture. If a corner is cut or a bright spot covers a date, retake that page before you save.
6. Save, then rename the document. Give the file a name the reader understands, such as "Alex Kim driver's license 2026". In the MRS library you can move it into a folder like "IDs" so you find it the next time someone asks.
7. Share it as one PDF. Open the document, tap Share and pick Mail, Messages, AirDrop or the app the requester uses. Sharing out of MRS needs MRS Premium; prices are shown in the app.

The part people get wrong: glare on laminated cards

Glare is the most common reason an ID scan gets rejected. Driver's licenses, state IDs and insurance cards have a glossy plastic surface, and a ceiling lamp or the phone's flash turns part of the card into a white patch. The patch often lands on the date of birth or the document number.

Turn off the flash in the scanner's top bar, move out from under the ceiling light and work next to a window with daylight coming from the side. If a bright spot stays, tilt the iPhone a few degrees; the scanner straightens the picture afterwards, so a slight angle costs you nothing.

Notes vs Files vs Camera photo vs a scanner app

The iPhone already has two document scanners. Apple's guide to scanning documents on iPhone shows both: in Notes you tap the Attachment button and then Scan Documents, and in Files you tap the More button, then Scan Documents, and choose where to save the PDF. Both capture automatically in Auto mode and let you add more scans before you finish.

Which one to pick

Notes or Files is enough for a single ID copy you will send once and never need again. A camera photo fits when a web form only accepts an image upload of one side; the guide on how to convert a photo to PDF on iPhone covers the opposite case. MRS fits when you send ID copies, leases and forms several times a year and want them in one private library: every scanned page gets on-device text recognition, so a search for your last name or "license" brings the file back, as explained in how to make a PDF searchable.

Tips for a readable ID copy

Light decides most of the quality. Daylight from a window to your side gives even light with soft shadows; a desk lamp straight above gives the strongest glare. Dim evening light makes small print soft.

Keep the card flat and fill the frame. A card is about the size of your palm, so the iPhone must come closer than for a letter page, while the scanner still needs to see all four corners. Clean the camera lens with a soft cloth first, because a fingerprint smear makes every scan look foggy.

Use color mode for IDs. Black-and-white mode makes text crisp on paper documents, but on an ID it can turn your photo into a dark block and wipe out the colored background print that shows the card is real. For more light and framing tricks, see scan like a pro with your iPhone.

The privacy rule: send only what is asked

A request for "a copy of your ID" rarely needs every ID you own. If the landlord asks for a driver's license, send the license, not the passport as well. The Federal Trade Commission tells consumers to ask why someone needs sensitive information and how they will protect it, and its guide for businesses says that without a real need for such data, "don't even collect it".

A visible note on the copy shows what it was made for. With the MRS text tool you can type a line anywhere on the page, such as "Copy for 12 Oak Street rental application, October 2026", in one of 7 fonts and 9 colors. Place it on an empty area of the card or below it, so it never covers your photo, your name or a number the reader must check.

How to check the scan before you send it

A one-minute check before you tap Send saves a second round of emails. Open the finished PDF and go through these signals.

• Edges: all four rounded corners are visible, with no table at the sides.
• Glare: no white patch on the photo, the dates or the document number.
• Order: page 1 is the front, page 2 is the back.
• Sharpness: the small print under the photo is crisp at normal size.
• Name: the file name tells the reader whose ID it is and what it is.

A zoom test

Pinch to zoom in on the smallest text on the card, usually the date of birth, the expiry date and the fine print on the back. If you can read every digit without guessing, the reader can too. In MRS, a second test is the library search: type your last name, and if the scan shows up, text recognition read the card, which means the print is sharp.

Common mistakes when you scan an ID

Most ID copies come back for small reasons that take seconds to fix.

• Using the flash: the flash bounces off the laminate and hides the dates. Turn it off and use daylight from the side.
• Two separate files: sending the front and the back as two photos makes the reader match them up. Scan both sides in one session so they share one PDF.
• A light surface: a white desk blends into the card's edges, and the scanner crops the wrong area. Use a dark, plain background.
• Scanning through a plastic sleeve: a wallet window adds a second layer of reflection and blur. Take the card out first.
• An expired card: many requests need a valid ID. Check the expiry date before you scan.
• Keeping copies forever: an old ID copy is a risk if your phone is lost. Delete scans you no longer need; MRS keeps deleted documents in Trash for 30 days before they are gone.

Edge case: passports and cards with holograms

A passport is a booklet, and its photo page curves toward the spine. Open it on the photo page, lay it on the dark surface and hold the pages flat with two fingers at the outer edges, away from the text. Scan only the photo page unless the request names other pages.

Holograms and security foils flash bright colors at some angles. Move the light source to the side or tilt the iPhone slightly until the foil turns dull over the text, and accept a small shine on areas without data. Readers expect the hologram to show; they need the text under it to stay readable.

Your ID scan checklist and next steps

A good ID copy meets six checks.

• Right ID: the exact document the request names, and it is not expired.
• Clean setup: a dark, plain surface, daylight from the side, flash off.
• Both sides, one file: front then back in one scanning session.
• Passed the zoom test: every digit readable, no glare on data.
• Clear name and note: a file name with your name and the ID type, plus a visible note on what the copy is for if you want one.
• Sent once, to the right person: shared directly with the requester, with old copies deleted when the job is done.

MRS keeps your ID copies on your iPhone, with no account and no upload, in folders next to your leases and forms, and its search finds them by the words printed on the card. The same scanner handles paper forms and receipts, as shown in how to scan documents on iPhone and how to scan receipts on iPhone. To start, download MRS; questions about the app go to MRS support.
