Do guests need to download an app?

No. Grain runs in the phone browser. Guests scan the QR code, pick a name, and start shooting.

Will it work on iPhone and Android?

Yes. Safari and Chrome both support the camera and upload flow.

How many photos can each guest take?

You choose a roll size, often 24 shots per guest. Once the roll is full, that guest is done.

Can guests see photos before the reveal?

No. The roll stays sealed until the reveal time you set, so the morning after stays surprising.

Wedding QR Code Guide - Disposable Camera App

Grain team · July 2, 2026

Why disposable cameras are coming back

Physical disposable cameras used to sit on every wedding table. Guests snapped the night, and the couple developed the film weeks later. Today, a disposable camera app does the same thing with the phones guests already carry. No hardware to buy, no film to develop, and no risk of a camera walking away.

How QR codes replace the camera basket

A wedding QR code is the modern equivalent of dropping a disposable camera on a table. Guests scan the code with their phone camera, enter a first name, and start shooting from their browser. The QR code removes every barrier: no app store, no login, no password, and no download.

Setting up your wedding QR code in three steps

Create your event in Grain and choose a reveal time
Download or print the QR code from the host dashboard
Place the QR code on menus, table cards, the seating chart, or the bar

Where to place QR codes for the best participation

One QR code on every table card so guests do not have to leave their seat
A larger code on the welcome sign or seating chart for the ceremony
A backup code near the bar or photo booth where people gather
A short note explaining that photos will be revealed later, so guests stay in the moment

The no-app-download advantage

The biggest drop-off in guest photo apps happens at the app store. With a wedding photo app that runs in the browser, guests scan and shoot in seconds. iPhone and Android work the same way, and the experience stays lightweight even on older phones.

Building the reveal into your timeline

The magic of a disposable camera is not seeing the photos until later. Set your reveal time for the morning after the wedding, or for a quiet moment on the honeymoon. The album, voice notes, and guestbook entries all unlock at once, turning the reveal into its own event.

Try it before the big day

Run a small test with your wedding party. Print one QR code, ask a few friends to scan and take a photo, and reveal the roll an hour later. You will spot the best placement, fix any wording, and know exactly what guests will see.
