# MeCard QR codes — how they work

> MeCard stores a contact in a compact single-line format that produces a QR code roughly 40% smaller than the equivalent vCard. It carries fewer field types and has slightly weaker desktop support, so it is the right choice when print size matters more than field richness.

## The payload

One line, semicolon-delimited, ending with a semicolon:

```
MECARD:N:Lovelace,Ada;TEL:+14155552671;EMAIL:ada@example.com;URL:https://example.com;;
```

| Field | Meaning |
|---|---|
| `N` | Name as `family,given` |
| `TEL` | Phone, international format |
| `EMAIL` | Email address |
| `URL` | Website |
| `ADR` | Address, comma-separated |
| `NOTE` | Free text |
| `ORG` | Organisation (not universally honoured) |

Escaping uses a backslash before `;`, `:` and `,` — the same trap as vCard, with the
same consequence when ignored.

## Why it is smaller

vCard spends bytes on structure: `BEGIN:VCARD`, `VERSION:3.0`, `END:VCARD`, a line
break per property, and type parameters like `;TYPE=CELL`. MeCard has none of that.

A name, one phone, one email and a URL:

| Format | Bytes | QR version at EC M | Modules |
|---|---|---|---|
| vCard 3.0 | ~180 | 8 | 49 × 49 |
| MeCard | ~95 | 5 | 37 × 37 |

That is a visibly coarser, more forgiving code at the same printed size — which matters
on a business card, a badge or anything printed under 2.5 cm.

## Where support is thinner

MeCard originated with NTT DoCoMo for Japanese feature phones. Today:

- **iOS camera**: recognised, offers to create a contact.
- **Android camera / Google Lens**: recognised.
- **Desktop scanners and some third-party apps**: many show the raw string rather than
  offering a contact import.

If the code will be scanned by phone cameras — which is nearly always — MeCard is
fine. If it might be processed by desktop tooling or older enterprise scanners, prefer
vCard.

## Choosing between them

Use **MeCard** when the printed code must be small, or when the contact is just a name,
one number, one email and a link.

Use **[vCard](/vcard-qr-code)** when you need job title, organisation, multiple typed
phone numbers, a structured address, or maximum compatibility with desktop software.

## FAQ

### Is MeCard better than vCard?
Neither is better; they trade richness for size. MeCard produces a code about 40% smaller with fewer fields. vCard carries more field types and has broader desktop support.

### Do iPhones read MeCard?
Yes. The iOS camera recognises MeCard and offers to create a contact, as does Android and Google Lens. Support is weaker among desktop scanning tools.

### Which fields does MeCard support?
Name, telephone, email, URL, address, note and organisation. There is no job title, no multiple typed numbers and no photo.

### Why is my MeCard contact importing wrongly?
Almost always unescaped semicolons, colons or commas inside a value — they terminate the field early. Generate the code rather than hand-writing the string.
