The essentials
An event QR code is a shortcut to your gallery link. To make it useful, print it with strong contrast and a clear margin, place it where guests can pause, and test the final sign on the phones and connection you expect. Keep the direct link available for anyone who cannot scan.

A QR code is the doorway to the guest flow
A QR code encodes information such as a URL. For event photos, it takes a guest to the collection page; the gallery service determines sign-in, upload, viewing and moderation requirements.
Capture guests open the event in a compatible browser and enter a display name. They can take or upload photos and use available gallery interactions according to host settings. The host creates and manages the event in the iPhone app.
Print for the position where guests will use it
DENSO WAVE specifies a quiet zone of four modules around a standard QR code. A module is one small square in the pattern. Keep text, borders and logos outside that margin and use a clear, high-contrast code.
For a table-card prototype, start with a code around 3–4 cm wide plus its clear margin. This is a starting point to test, not a minimum that guarantees a scan. Enlarge it for a wall sign or a longer viewing distance; code density, lighting, focus and camera quality all matter.
Print a sample at the final size. Avoid folds through the pattern, reflective covers and busy backgrounds. If you resize an image, inspect the squares for blur before producing the full batch.
| Placement | Likely problem | Practical check |
|---|---|---|
| Table card | Dim light, candles, flowers or glasses covering the code | Scan from a seated position with the finished table setting. |
| Welcome sign | A queue or guests standing farther away | Test from the distance at which someone can safely stop. |
| Venue screen | Glare, a moving slide or low brightness | Hold the code on screen long enough to scan; test from the back of the viewing area. |
| Invitation or website | Guest reads it on the same phone they would scan with | Provide a tappable direct link alongside the code. |
Run and record a real scanning rehearsal
Use the log above with an iPhone and an Android phone representative of your guests. This is a test procedure for your event; no universal device success rate is claimed.
- Scan the finished print with the phone camera or its available QR scanner. Record device, browser, lighting, distance and result.
- Check that the expected event name opens. A successful camera scan alone does not prove the upload flow works.
- Join as a guest and contribute a test photo. Wait for upload confirmation and check approval or reveal behavior.
- Move the sign to its actual venue position. Repeat with the final lighting and available mobile or Wi-Fi connection.
- If scanning fails, enlarge or reposition the code and retest. Keep the direct link and assistance available.
Introduce the code where people have time to act
Put one short invitation beside the code: “Share a few photos from your table. Scan here or open [LINK].” Tell guests who will see uploads and whether photos may appear on a screen.
A brief MC reminder and a follow-up with the same link help people find the collection. Avoid promising a scan or upload time: a guest’s connection, file size and browser all affect the result.
Manage destination and access changes
A printed code keeps encoding the same information; the destination may change or stop being available. Check that your event is open before sharing signs and set an appropriate collection window.
Hosts can regenerate the event QR code in the Capture iPhone app. Replace distributed signs and links as needed, then check guest access. Regeneration cannot recall files or screenshots already saved by recipients.
A code is not a guarantee of safety or identity. Inspect the destination before entering information, and periodically check that physical signs have not been covered by an unrelated code.
Questions & answers
Do guests need a separate QR-scanner app?
Many current phones scan through the camera or a built-in scanner, but behavior varies by device. Test representative phones and provide a direct link.
How large should the printed code be?
Choose size for the intended distance, density and lighting. Start with a sample, preserve the clear margin, and enlarge it until it scans reliably in the actual position.
Can I regenerate an event code?
Yes. Hosts can regenerate the event QR code in the Capture iPhone app. Update distributed materials and check intended guest access afterward.
Does scanning work without internet?
The phone may read the code without internet, but opening the online gallery and completing uploads requires a working connection.
What if someone cannot scan?
Send the direct gallery link through an existing guest channel and offer help opening it. They can also keep their original photos and contribute later while uploads remain enabled.
