Make a medical ID card and emergency contact card
This medical ID card maker puts the facts a paramedic, doctor or passer-by needs first — your blood group, allergies, medical conditions, medicines and who to call — onto a wallet-size emergency contact card you can print at home. The same details become a phone lock-screen image, readable without unlocking the phone, and an optional QR code with the information as plain text.
It works entirely in your browser. Nothing you type is uploaded or stored on a server, and nothing is saved at all unless you tick “Remember on this device”. That matters for health details: you decide where they appear.
How to use the Medical ID Card Maker
- Fill in your name, date of birth and Blood group, then list allergies, conditions and medications, separated by semicolons.
- Add up to three emergency contacts with relationship and phone number (with country code if you travel), and your doctor.
- Choose how many cards per sheet, the accent colour and the paper size. Tick the QR option if you want one.
- Press Print cards or Download PDF, print at 100% scale, cut along the grey outline and fold on the dashed line.
- Pick your phone’s Screen size and press Download lock-screen PNG, then set it as your lock-screen wallpaper.
Medical ID Card Maker features
Real wallet-card size
Each side is 85.60 × 53.98 mm with 3.18 mm corners — the ISO/IEC 7810 ID-1 size of bank and ID cards — so it fits a card slot or sleeve.
Fold-over front and back
Front: name, birth date, blood group, allergies (highlighted), conditions, medicines. Back: emergency contacts, doctor, other notes and the optional QR code.
Lock-screen image
Exact pixel sizes for common phones, with the details kept in the middle band away from the clock and the shortcut buttons.
QR code as plain text
Any phone camera shows the text without an app or internet connection. Generated with the open-source qrcode-generator library (MIT).
Fit warnings
If a long medicine list will not fit, the tool shrinks the text a little and then tells you exactly which section was shortened.
Nothing leaves your device
No account, no upload, optional local saving that you can switch off again.
What to put on an emergency medical card
Your doctor or pharmacist can tell you which of your details matter most in an emergency.
- Allergies to medicines (penicillin, sulfa drugs, NSAIDs), foods, latex or insect stings — the most important line on the card.
- Conditions that change emergency treatment: diabetes, epilepsy, asthma, heart disease, adrenal insufficiency, a pacemaker or implant, blood thinners, pregnancy.
- Current medicines with dose and frequency — especially insulin, anticoagulants, steroids and heart medicines.
- Two contacts who are likely to answer, written with the country code (+91, +44, +1).
- Blood group only if you know it from a lab test. Hospitals test blood before any transfusion, so leave it as “Not stated” if you are unsure.
Printing, folding and keeping it safe
Print at “Actual size” or 100% — scaling to fit the page makes the card smaller than a bank card. Card stock of 200–300 gsm or a self-laminating pouch makes it last; a clear card sleeve works too. If the QR code is turned on, print at 300 dpi or better and check it with your phone camera before relying on it. Keep the card behind your bank card or ID, and tell your emergency contacts that you carry it.
Review the card every few months, or whenever a medicine changes. The “Last updated” line shows how current it is. For a full list of times and doses, keep a medication schedule, and for a QR code that opens a web page, use the QR code generator.
The lock-screen image and your phone’s built-in medical ID
Phone lock screens show the clock and widgets near the top and shortcut buttons near the bottom, so the tool keeps your details between about 36% and 86% of the screen height. Turn on the preview guides to see those areas. Layouts vary between phone models, fonts and settings, so look at the result on your own phone.
Most phones also have built-in emergency information — Medical ID in the iPhone Health app and Emergency information on Android — that responders can open from the emergency call screen. Fill that in as well. A card and a wallpaper help when the phone is locked, flat or not yours to open.
Medical ID Card Maker FAQ
Is this medical ID card official?
No. It is a personal information card that you write and print yourself. It is not issued or checked by a doctor, hospital or government, and it is not a medical alert service.
Is my medical information safe?
Everything is processed in your browser and nothing is uploaded. The details are saved only if you tick “Remember on this device”, and unticking it removes them. Anyone who finds the card or sees the lock screen can read it, so include only what you are comfortable sharing.
What size is a wallet medical ID card?
85.60 × 53.98 mm (3.370 × 2.125 in), the ID-1 size used for bank and ID cards. The tool prints both sides side by side so you can fold them back to back.
How do I put a medical ID on my lock screen?
Choose your phone’s screen size, download the lock-screen PNG, open it from your photos and set it as the lock-screen wallpaper. Also fill in your phone’s built-in emergency information.
What does the QR code contain?
The same details as the text copy, as plain text — no web link. Any camera app can read it offline. Because it is not encrypted, treat it like the printed card.
Can I make an emergency contact card for a child or parent?
Yes. Enter their details instead of yours, print a card for their bag or wallet and a copy for yourself, and keep both up to date.
