QR Codes for Event Check-In

You print badges two weeks out. The check-in form is still a draft. Rooms will move. I want the square on the lanyard to open the form you are using at 8am, not the Eventbrite URL you had in March.

Staff can scan a badge. Guests can scan a poster. Either way the phone should land on one job: check this person in, this hour. If you also need the agenda, print a second code. A hub page in a doorway is a bounce.

Print a short link, not the form

A static code writes the final URL into the pixels. There is nothing to edit. Print that on 200 posters and the first form swap makes every board wrong. A dynamic code writes a short link. You change the destination. Same image. New form. New room.

On this site you create a QR code as Link. Do not pick Event for a door poster. Event writes a calendar invite into the image. That payload is static. If the start time slips, every printed square is still the old time. Put the calendar button on the page behind the link if people need it.

Door, badge, and ticket email

QR codes for event check-in belong on the door, the badge, and the ticket email. Give each surface its own short link if you want a clean report. One code is fine if you will retarget it when check-in closes.

• Door poster: guests scan themselves. Opens the form you are using this hour.
• Badge: staff scan at the line. Opens the attendee record or the same form.
• Ticket email: the pass, not the agenda. People open mail on the train.
• Chair card or program: today's grid, then the replay. That is a different job.

Conferences do this on lanyards. Weddings do it on programs. Churches do it on door cards. The print job changes. The rule does not: one scan, one answer. See conferences, weddings, and churches if that is the surface you are printing.

Rooms move after the print run

You tape a URL on a door when the program breaks. Guests type it wrong. Staff rewrite it in marker. That is the failure a dynamic destination is for. Keep the card. Change the link. The holder on the frame does not need a new insert.

I would rather edit a URL at 10pm than reprint 400 boards at 6am. Rain venue, canceled speaker, flooded breakout — same square. If you encoded a raw ticketing path, you reprint. That is why you create a QR code before you send art to the badge vendor.

Livestream now. Replay later.

The foyer poster still gets scans on the way out. People photograph it. Monday someone opens that photo. Point the same short link at the live stream, then the recording, then the survey. You do not need a new foam board for the recap.

Booth codes you can report

Sponsors ask which booth was busy. A shared event URL cannot answer that. Create one code per booth. Point each at that sponsor's form or a tagged page. Scan totals by code are the Monday email. Keep the placements that worked. Drop the ones that sat.

Size the square for the door

Your monitor lies. A 3 cm code that locked on your desk fails on an easel with people in the way. Use distance, not layout taste. Printed width should be about one tenth of the scan distance. Add margin for glare and laminate.

Black modules on a light panel. Leave a quiet zone. Matte beats gloss under lobby lights. Add Scan to check in in plain type. Test from the real spot with an older Android and a current iPhone before you print the run.

Download, confirm email, pay $1

Here is how I create a QR code for a door that still might change.

1. Paste the check-in URL. Your own page is better than a listing that can expire. Pick Link, not Event.
2. Hit Download. We ask for email so the code attaches to your account.
3. Confirm the email we send. Check spam if it is slow.
4. Pay $1 to unlock the 1024px PNG. Place it at the size the door needs. Keep it square.

When the form or room changes, open the dashboard and edit the URL. Do not generate a new image unless the poster design changed. Printed /r/ links keep scanning if the dashboard later locks. You cannot edit them until you start a plan.

Mistakes that waste a print run

• Using the Event type in the generator on a poster that might change.
• Encoding a Facebook or Eventbrite URL you will later lock.
• One tiny square trying to do check-in, tickets, and the program.
• A 3 cm door poster because it looked cleaner on the layout.
• Skipping the door scan until guests arrive.
• Putting the code on a photo or under gloss that blinds at noon.

If a printed code already failed, you can only repair it without reprinting when it is dynamic and you still own the short link. For the next run, create a QR code first, then print the poster.
