Checklist Before Printing Business Cards with QR Codes

Business cards with QR codes serve as gateways from paper to profiles and websites. However, looking good on a screen is not the same as being scannable by a smartphone after printing. Incorrect links are also difficult to fix once printed.

Before submitting your files, check the destination link, margins, print quality, and actual scannability in that order. This article provides a checklist for readers to perform their own test printing and scannability checks. It does not guarantee success for specific business card sizes, printing methods, or smartphones, nor does it reflect results from testing with physical items.

Confirm the destination link first

First, decide what you want the recipient to see. Choose a gateway that suits the purpose of handing out the business card, such as a public profile for introductions or a company or service information page for follow-up to a business meeting. Do not mistake the admin screen or a page viewable only by you for the public URL.

• Can you open the target page as a recipient without relying on your own logged-in status?
• Do the name, company name, and contact information match the content on the card?
• Do the links on the page for phone numbers, email, appointments, documents, etc., lead to the intended destinations?
• Is it a temporary test page or a campaign URL scheduled to expire?

You cannot determine whether the embedded URL is correct just by looking at the QR image. Scan the original QR image and check both the displayed URL and the page that finally opens. If you use a shortened URL or redirection service, also record the administrator and the terms of continued use.

Adding a short label next to the QR code, such as "View profile" or "Company information," makes it easier to guide recipients. You can also leave necessary contact information, such as an email address, on the card so people can contact you even if they cannot scan it. The Digital Business Card Information Organization Guide is also helpful for choosing what information to include.

Check the QR code's margins, size, and color

Standard QR codes require a clear area around the pattern. Denso Wave's official instructions recommend ensuring a margin of at least 4 cells on the top, bottom, left, and right. A cell is one of the small squares that make up a QR code. Check the official margin instructions and avoid cropping out the white area around the QR image as unnecessary blank space.

It is also important not to overlap text, lines, or logos with that margin. When placing the QR code near the edge of the business card, check the printing company's trimming and bleed specifications separately from the margin required by the QR code itself. Even if the paper's finished position shifts, ensure the layout does not cut into the required area.

Size cannot be uniformly determined by a rule like "it will always be scannable at X mm." Denso Wave explains that you need to consider the code's cell size, printing conditions, and scanning device. Before making it small and compact, consult with the printing company about the resolution and finish of the submission data. The official cell size instructions are also helpful.

For reliability, it is safest to use black on a white background and prioritize scannability. Denso Wave also recommends against overlapping logos or distorting the pattern, as this may affect scannability. You can express your brand colors in the heading outside the QR code or in the card's layout. If you choose colored ink, special paper, or glossy finishes, check them under conditions close to the final finish. The official FAQ contains notes on colors and finishes.

Verify scannability with a full-size test print

Do not stop checking after viewing an enlarged image in design software; scan a printout at the final size. A test print from a home printer can help you check the layout and URL, but it has limits in reproducing the actual paper, printing, and finishing. For special finishes or large orders, it is also reassuring to consult the printing company about proofing and sample options.

• Print at full size from the final file you plan to submit and check that no unauthorized scaling has occurred.
• If possible, test it on multiple smartphones using the camera or scanning function you normally use.
• Check it under brightness and handling conditions similar to when you actually hand out the business card. Also record conditions where reflections or shadows are noticeable.
• Check not only that the code is detected, but also that the target page displays and necessary link operations work.
• After making corrections, repeat the same check with the corrected file.

Rather than checking that it scanned once, verify that it can be used repeatedly under the same conditions without issues. However, success on the device you tested does not guarantee success on all devices or in all environments. Record the scope of your check to leave a basis for your judgment.

Checklist for use before submitting files

Next is a checklist template you can use within your company. Including the person in charge, the check date, and the data version number makes it easier to prevent accidentally submitting an old file after checking.

When placing an order, compare the file you submitted to the printing company with the confirmed file. After it arrives, also scan it from the physical item before you start distributing it. If there is a difference between the test print and the final finish, it will be easier to determine at which step the change occurred.

Troubleshoot scannability issues one by one

The places to check differ depending on whether the camera does not detect the code or whether the URL is displayed but the page does not open. For the former, review the margins, size, blurriness, print blurring, and reflections. For the latter, check for URL errors, publication settings, network conditions, and the status of the destination link.

When making improvements, do not change multiple things at once; change one condition at a time and record the results. For example, compare it with a version where the same code is placed slightly larger, or compare it after changing it back to black on a white background. Distinguish between the versions before and after corrections, and recheck with the data you ultimately adopt.

If you want to organize how you use paper and digital business cards together, see the Operational Guide for Using Paper and Digital Cards Together. Even when guiding people to a QR code in situations where NFC cannot be used, an internet connection is required to open a web page.

With Share-Me, you can put your profile QR code on paper business cards

With Share-Me, you can download the QR code image of your digital business card and include it on paper business cards or materials. You can leave necessary contact information on the card and consolidate the link to your detailed profile or website on the QR code.

Before publishing, scan the downloaded QR code to confirm that it leads to the target profile. Even after incorporating it into the card design, perform a full-size printout and display check using the checklist in this article before submitting the files.
