Contact QR Code
Enter a name, phone number, email and company to generate a contact QR code in vCard or MECARD format and save it as a PNG. When someone scans it with a phone camera, they can review and save the details in their contact app. Use it on business cards, email signatures, signs and more. All input stays in your browser and is never sent externally.

Enter a name to generate a QR code
How to use
Pick a format (vCard / MECARD), then fill in name, phone, email and company. The QR appears as soon as a name is present and regenerates on every change. The example chips fill a sample contact in either format. When it looks right, use Download PNG to export the image.
Fields and QR content
- Format: vCard 3.0 is an international standard supported by many phone contact apps. MECARD is a compact format common on Japanese phones.
- Name: For vCard, the last word becomes the family name and preceding words become the given name. A single word is treated as the family name. The display name (FN) preserves exactly what you enter.
- Phone, email and company: These fields are optional. Only the details you enter are included in the QR code.
- Symbol escaping: Semicolons, commas and line breaks are escaped automatically so they do not break the contact format.
- Spec compliance: vCard output uses CRLF line breaks and folds long lines at 75 octets as required by RFC 2426. MECARD records end with
;;.
Concrete examples
- Taro Yamada / 03-1234-5678 / [email protected] (vCard) → a vCard 3.0 with
N:Yamada;Taro;;;andFN:Taro Yamada - Same contact (MECARD) →
MECARD:N:Taro Yamada;TEL:03-1234-5678;EMAIL:[email protected];; - Name only "Benri.dev" →
N:Benri.dev;;;;(a single word is the family name); FN is also Benri.dev - Company "A;B Trading" → the semicolon is escaped to
ORG:A\;B Tradingso the format stays valid - Download PNG → drop it on a business card, signature or storefront; scanning adds the contact in one step

FAQ
Is my data sent to a server?
No. Everything runs in your browser; nothing is transmitted or stored externally.
vCard vs MECARD?
vCard is the international standard (VCARD:3.0) that most phone contact apps read. MECARD is a compact format common on Japanese phones. Pick what your reader expects.
How are first and last name split?
If the name has a space, the vCard N line uses the last word as the family name and the preceding words as the given name (for example, Taro Yamada becomes N:Yamada;Taro). A single word is treated as the family name. The display name (FN) keeps exactly what you typed.
Can values contain symbols or semicolons?
Yes. Per the vCard/MECARD spec, ; , \ and newlines are escaped automatically before going into the QR, so the format stays valid.
How does the recipient save the contact after scanning?
Point the phone's camera or QR reader at the code. A compatible contact app opens so the recipient can review and save the details. vCard works with the standard QR features on many iPhones and Android phones. If it does not open, try the device's QR reader app.
Is there a limit to how much information a QR code can hold?
The technical limit is generous, but more data produces a denser pattern that becomes harder to scan when printed small. For reliable results, keep it to details such as name, phone, email and company, and avoid long addresses or notes. For print, use a size of at least 2 cm square and leave clear space around the code. If the details exceed the limit, the QR code is hidden and an error is shown, so a stale code is never left on screen.
