QR codes can enhance marketing campaigns, streamline operations, and improve customer engagement. However, for businesses that operate within the European Union (EU) or handle the data of EU citizens, the use of QR codes must comply with the General Data Protection Regulation (GDPR). The GDPR is designed to safeguard personal data and ensure that companies handle this data responsibly. Since QR codes often connect users to platforms or forms that collect personal information, businesses must follow strict guidelines to avoid violations.
In this article, we’ll explore what GDPR entails, how it applies to businesses using QR codes, and how to ensure compliance.
The General Data Protection Regulation (GDPR) came into effect on May 25, 2018, to enhance privacy rights for individuals in the EU and strengthen data protection practices across the region. GDPR applies to any business that processes personal data of EU citizens, regardless of the company’s location. This makes GDPR one of the most comprehensive privacy laws globally, affecting businesses worldwide.
The regulation introduces stringent requirements on how personal data must be collected, stored, processed, and transferred. GDPR also provides individuals with significant rights, including the right to access, correct, and delete their data.
Non-compliance with GDPR can result in substantial fines, up to €20 million or 4% of a company’s annual global revenue—whichever is higher.
A QR code is essentially a barcode that stores information that can be scanned and read by a smartphone or device. While the QR code itself doesn’t directly store personal data, the pages, forms, or systems it links to often do. For example, a QR code might redirect users to a website where they input personal details such as their name, email, or payment information. QR codes may also be used to track user engagement, scan frequency, or location data.
If the use of a QR code involves processing any kind of personal data, GDPR applies. Therefore, it’s essential for businesses using QR codes to ensure that they are handling the data lawfully and transparently.
Under GDPR, there are several key principles that businesses must adhere to when collecting and processing personal data. Here’s how these principles apply to QR code usage:
Businesses must ensure that the processing of personal data through QR codes is lawful. This means there should be a clear legal basis for collecting data, such as obtaining user consent, fulfilling a contract, or satisfying a legitimate interest.
For example, if a QR code is used in a marketing campaign that collects personal information, the user must be informed about how their data will be used. Transparency is key: businesses must provide users with clear information about the data they are collecting, the purpose of the data collection, and how it will be used.
QR codes must be used in a way that aligns with the purpose of data collection. Data collected via a QR code must be used only for the purpose it was collected for. For instance, if a QR code is used for an event registration, the data collected should not be repurposed for marketing or shared with third parties unless users have given explicit consent for that purpose.
The data collected via QR code interactions should be limited to what is necessary. If the QR code links to a form, only request the essential information needed for the transaction or service. For example, if you’re using QR codes to deliver a digital product, there is no need to collect excessive personal data like addresses or phone numbers unless absolutely required.
GDPR mandates that personal data must be kept accurate and up to date. If a QR code directs users to an online platform where they input data, businesses should allow users to easily update or correct their information if necessary.
Personal data should not be stored for longer than necessary. QR code-related data, such as customer information or analytics from scans, should be deleted once it has served its purpose. For example, if a QR code is used to gather event registrations, delete the data after the event unless there is a legitimate reason to keep it.
Businesses must ensure that data collected through QR codes is kept secure. This involves implementing appropriate technical measures, such as encrypting the data transmitted through the QR code link or using HTTPS protocols for the websites or platforms connected to the QR code.

To ensure GDPR compliance when using QR codes, businesses need to take the following steps:
Wherever the QR code leads, such as a landing page or a form, businesses must provide a GDPR-compliant privacy notice. This notice should explain what data is being collected, why it’s being collected, how it will be processed, and who it will be shared with (if applicable). This notice should be easily accessible and written in plain language.
If the QR code leads to a platform that collects personal data, businesses must obtain explicit consent from users before collecting their data. This is particularly important for marketing activities. A consent form should clearly state what data is being collected and what it will be used for. Users should also have the option to withdraw consent at any time.
Ensure that any websites or platforms linked to QR codes are secure. Always use HTTPS protocols to protect the data that users might enter after scanning the QR code. In addition, consider using encryption for sensitive information like payment data or personally identifiable information (PII).
GDPR gives individuals the right to access the personal data a business holds about them. If a QR code is used to gather personal information, businesses must have procedures in place to respond to requests for data access, rectification, or erasure. Users should be able to easily contact the business to exercise these rights.
QR codes are often used for tracking customer engagement or analyzing marketing campaign performance. While this data is valuable for businesses, it must be collected in compliance with GDPR. Avoid tracking personally identifiable information unless users have given explicit consent. If using QR codes for analytics, make sure to anonymize the data where possible to protect user privacy.
Regular audits of data processing activities can help ensure ongoing compliance with GDPR. Businesses should review how QR code data is being collected, processed, and stored. Any issues should be addressed promptly to ensure that all data processing remains lawful and transparent.
Marketing Campaigns: QR codes are commonly used in marketing materials to direct users to special offers, loyalty programs, or event registrations. In these cases, it’s important to provide users with clear information on what data will be collected, how it will be used, and how long it will be stored. Ensure that explicit consent is obtained before collecting personal information for marketing purposes.
Customer Feedback: QR codes can be used to gather customer feedback by linking to survey forms. When collecting feedback, businesses should only request relevant information, such as the customer’s name and email address. If personal data is collected, ensure that users understand how their feedback and data will be used.
Event Registrations: QR codes are frequently used for event registration and ticketing. When collecting registration data, businesses must provide a privacy notice and obtain consent for any additional marketing or data-sharing purposes. After the event, personal data should be deleted or anonymized if it is no longer needed.
QR codes offer immense potential for businesses, but their use must be carefully managed in the context of GDPR. The key to compliance lies in transparency, user consent, data minimization, and strong security practices. By taking the steps outlined above, businesses can confidently use QR codes to enhance customer engagement while staying compliant with the GDPR’s strict data protection standards.
In the rapidly evolving digital landscape, understanding and implementing GDPR compliance is essential for maintaining customer trust and avoiding costly fines. As businesses continue to embrace QR codes through platforms like QR Code Developer as part of their digital strategies, staying mindful of privacy laws is more important than ever.
