MOJA — Conference Badge QR Codes

Conference Badge QR Codes

A conference badge QR code carries who someone is — name, role, company and which conference — printed on the badge itself, so a scan swaps details without anyone typing. Badge codes are made in the MOJA app rather than here.

How to create a Conference Badge QR code

Open Create in the app and pick Conference Badge Under Events & Access. There is no web form for this type, which is why this page has none.
Fill name, role, company and the conference ID All four go into the code as text. The conference ID is what stops a badge from last year reading as a badge for this one.
Avoid semicolons and colons in the values They separate the fields and are not escaped, so a job title written "Engineer; Platform" cuts the record short. A comma or a hyphen is safe.
Print it large enough to scan across a table Badges are read at arm's length, so roughly 3 cm is plenty — the working rule is that a code reads from about ten times its own width.

What a Conference Badge QR code is for

The code holds BADGE:NAME:…;ROLE:…;COMPANY:…;CONF:… as plain structured text. It is not a link and nothing is fetched, so it works in a hall with no signal — which is most halls once a few hundred people arrive.

What it replaces is the business-card exchange: point a phone at a badge and the other person's details are on screen, spelled correctly. What it does not replace is a contact card — the details are shown, not written into the address book. For that, a Contact Card (vCard 3.0) code is the right type and you can make one here for free.

Everything in it is readable by anyone. A badge is worn in public and the code can be scanned from a metre away without asking. Put on it exactly what you would be happy shouting across the room, which usually means a work email rather than a personal mobile.

Where a Conference Badge QR code earns its place

Conferences that print their own badges

The registration list already has name, role and company. Printing the code costs nothing extra and saves every attendee from typing the same four fields at every conversation.

Trade stands and exhibitions

Stand staff scan visitors rather than collecting cards, and the details arrive spelled the way the visitor spelled them rather than the way somebody read them off a card.

Internal offsites and training days

A hundred people who half-know each other. The badge answers "which team are you on" without anyone having to ask twice.

Conference Badge format notes and limits

It shows details, it does not save them. Scanning a badge displays the fields; it does not write a contact. If the goal is to land in the address book, use a contact card (Contact Card (vCard 3.0)) instead — that type is free on this site and imports on any phone.

Only the MOJA app reads it back as a badge. This is a MOJA format rather than an open standard, so any other scanner shows BADGE:NAME:… as raw text. At an event where attendees use whatever scanner they already have, that is a real limitation.

Semicolons and colons end a field early. The values are not escaped, so punctuation inside a company name or a job title truncates the record.

The badge is public, and so is the code. There is no encryption and no access control: anyone within scanning distance can read every field.

Conference Badge QR codes — questions people actually ask

Can I make a badge code on the website?

No, this type is app-only. If you need something you can generate here, a contact card (Contact Card (vCard 3.0)) covers the same conversation and has the advantage of importing into the phone rather than only displaying.

Will the details save to my contacts when I scan a badge?

No. A badge code displays the fields; it does not create a contact. That is the main practical difference between this and a contact card.

Can other people’s scanner apps read it?

They will read the code and show the raw text. Only the MOJA app lays it out as a badge. If attendees are bringing their own apps, expect most of them to see a line beginning "BADGE:".

Is it safe to put a phone number on a badge code?

Treat it as public. A worn badge can be scanned from a distance without you noticing, so put a work address on it rather than a personal number.
