At an exhibition or family gathering, a QR code can save everyone from typing an album address. Before printing the card, check two separate things. A phone should be able to read the address encoded in the pattern, and that address should open the intended album with the recipient’s permissions.

Choose the right address

Copy the album link intended for recipients instead of the editing or administration page. If the link expires, consider how long people will use the card. A person holding the card can pass on the address. Apply any access restriction in the album’s settings.

Leave a clear margin around the pattern

A dark pattern on a light background is a practical starting point. Preserve the empty border and keep nearby text out of it. DENSO WAVE describes a four-module margin on every side of a standard QR code. Keep that margin when placing or cropping the code in a layout. DENSO WAVE guide to QR code margins

Try two phones at the final size

A large code on a monitor and a small printed card are different tests. Scan a proof at its intended size and under the light where people will use it. When the first phone offers a link, read the domain and open the album. Repeat with another phone and browser.

Give people another way to reach the album

Near the code, provide a recognisable short address or a way to request the album. If a link is personal, avoid distributing the code in a public place. When the album will change later, keep track of where the cards are used. Decide what replaces the old address when it expires.

Plan the link's lifetime before printing

Imagine putting a QR code for a wedding album on cards at each table. The link may work at the event, but guests might open it a week later. Decide how long the album should be accessible before designing the code. If people need to sign in, explain that on the card. Before the photos arrive, you can use a clear waiting page at the same destination. A wrong address is difficult to repair once the cards are printed. If you use an address whose destination can change, check the access and retention conditions of that address as well. Add a short label so people know they are opening the intended album. If it will appear later, say when they should return. Check that you have not left a private administration page or personal test address as the target. A readable alternative address gives guests a way to reach the album without a camera.

Test a printed sample where people will use it

A code that scans easily on a monitor may behave differently on paper. Print one copy of the final design at its actual size. Scan it under the lighting people will encounter, from a normal distance and at a slight angle. Glossy stock or a nearby lamp may reflect across part of the pattern. If you have to hold the phone in an awkward position, change the placement. Keep the blank area around the pattern clear of decorative borders and text. Reopen the print file and check that resizing has not softened the edges. Try a second phone too. After scanning, confirm the album name is right and the first picture loads promptly. Record the result beside the filename and version of the print artwork. If you print replacement cards later, the note lets you check where the old and new copies lead. When the album should close, repeat a scan so the message visitors see after expiry is clear.
