QR Code Legal Issues - Trademark, Privacy and Advertising Compliance Guide
"QR Code" Is a Registered Trademark
"QR Code" is a registered trademark of Denso Wave. Using it in blog posts or conversation is fine, but caution is needed when using it in product or service names.
For commercial use, Denso Wave recommends including "QR Code is a registered trademark of Denso Wave Incorporated." Verify trademark compliance when including "QR Code" in your product names.
Personal Information Handling
Storing personal information in QR codes is subject to privacy protection laws. Putting your own contact in a business card QR code is your choice, but distributing QR codes containing others' personal information requires their consent.
When dynamic QR codes collect scanner location or device information, privacy policy disclosure and consent collection may be required.
Advertising Regulations
Displaying "Scan to win luxury prizes!" next to QR codes is subject to advertising regulations. If actual winning odds or prize details differ from the display, it may constitute misleading advertising.
Campaign pages accessed via QR codes are held to the same legal standards as regular advertising. Being "behind a QR code" doesn't relax regulations.
For general prize draws in Japan, where winners are decided by lot, the premium rules set the following caps.
| Transaction value | Maximum prize value | Total value of prizes |
|---|---|---|
| Under 5,000 yen | 20 times the transaction value | 2% of the projected total transaction value of the campaign |
| 5,000 yen or more | 100,000 yen | 2% of the projected total transaction value of the campaign |
These caps are set by the Japanese public notice on premiums offered through prize competitions, which is administered by the Consumer Affairs Agency.
Protecting Against Misuse
Prepare for risks of third parties misusing your QR codes. Overlay scams pasting fake QR codes over legitimate ones may violate unfair competition and fraud laws, but prevention is key.
Effective measures include regularly scanning your QR codes to verify correct destinations, using tamper-evident seals, and monitoring scan count anomalies with dynamic QR codes.
Responsibility extends to the destination's content too
When installing a QR code, what tends to be overlooked is that responsibility extends to the content of the destination page too. The code itself is only a pattern, but what the person who scanned opens is a page you prepared. If there is inaccurate information or misleading expression there, the side that posted the code comes to be held accountable. Even when guiding to a page made by a third party, guiding without confirming its content can become a cause of trouble. The code is an entrance, and an attitude of taking responsibility including what lies beyond it is required.
Preparing for replacement and tampering
A QR code posted at a storefront or on a poster carries the danger of being replaced with a different code by a third party. If it is swapped for a malicious code, users may be guided to a fraudulent site and harm may arise. The side that posted it needs the consideration of periodically confirming whether the code it installed is the legitimate one, and patrolling for any suspicious replacement. If you also write the correct destination in text near the code, users find it easier to notice a difference. Not ending with installing, but keeping an eye on the state after posting too, leads to protecting users.
Copyright and QR Code Design
When creating design QR codes with logos or illustrations placed in the center, pay attention to the copyright of the images used. Embedding another company's logo or copyrighted material into a QR code without permission may constitute copyright or trademark infringement.
Using your own logo is fine, but when using free stock images, check the license terms. Using materials that prohibit commercial use in a commercial QR code would violate the license.
Using QR codes is free, but the rules around them touch several areas. The points worth checking before you start are these.
| Law or right | When it comes up | What is expected |
|---|---|---|
| Trademark | Using the name "QR Code" in print or on a website | Add a note that it is a registered trademark. Generating and using codes costs nothing |
| Personal information protection | Collecting names or email addresses on the destination page | State the purpose of use, obtain consent, keep the data secure, and report leaks |
| Premiums and representations | Handing out coupons or running a prize campaign | Show the winning conditions accurately and stay within the prize caps |
| Copyright and trademark | Placing a logo or illustration in the center of the code | Check that the artwork is your own or licensed for commercial use |
