How to Scan a Vaccination Record with Your iPhone
Flatten the card or open the booklet fully, capture in Document mode under even light, and scan every page that has an entry on it — a school or employer will want the whole immunisation history, not just the most recent dose. Handwritten entries and small clinic stamps are the fragile part, so check them at full zoom before you export. Everything is processed on your iPhone and not uploaded to a server.

Step by step
-
Flatten the card before capturing
Vaccination cards get folded to fit a wallet, and the fold usually lands right across the dose dates. Leave the card flat under a book for a few minutes; a residual crease throws a shadow line that both hides handwriting and confuses edge detection into cropping the card in half.
-
Open a booklet flat and shoot each page
For a yellow international certificate or a childhood immunisation booklet, press the spread open and capture each page that carries an entry as a separate page. Keep them in order — a reviewer reading dates out of sequence will assume the record is incomplete.
-
Light it evenly for the handwriting
Most entries are handwritten in ballpoint by whoever gave the dose, and pale blue ink under uneven light is the first thing to disappear. Even, indirect light across the whole card beats a bright spot in the middle, and it also keeps the clinic's ink stamp legible.
-
Do not over-process
Resist pushing Brightness & contrast hard to make the handwriting "pop" — it thins faint strokes until digits break apart and a 3 starts to look like an 8. Nudge it only if a page is genuinely dim, and use Crop & perspective fix to square the page instead.
-
Export the whole record as one PDF
Export every page as a single PDF so the history stays together. Before you send it, check that the vaccine names, dates, lot numbers, and the administering clinic's stamp are all readable at full zoom — those four things are what gets checked.
Frequently asked
- Will a scanned vaccination record be accepted?
- Schools, employers, and travel operators often accept a clear scan, but some border authorities require the original yellow booklet with its physical stamps, and a few require an official digital certificate instead. Check the specific requirement for your destination or institution before travelling on a scan alone.
- Can OCR read the handwritten entries?
- Not reliably. Text recognition is built for printed text, and clinical handwriting is the hardest case there is. Treat any OCR output on a vaccination card as a rough hint and read the dates off the image yourself.
- The card is thermal-printed and the text is fading. Can I fix it?
- Capture it now, before it fades further — thermal paper keeps degrading and heat accelerates it. A small contrast increase can help a faint but intact print, but it cannot restore ink that has already gone. If the original is near-illegible, ask the issuing clinic for a reprint.
- Should I scan the back of the card?
- Yes if there are entries, boosters, or a stamp on it — many cards continue the record on the reverse and people routinely forget it. Add it as another page in the same PDF.
- Is my health information uploaded anywhere?
- No. Capture and text recognition run on the device using Apple's built-in frameworks, and document images are not sent to a server. Export to PDF or JPG is free with no watermark and no account required.
