Perlindungan Data (GDPR) dan QR Codes

Data Protection (GDPR) and QR Codes

The General Data Protection Regulation (GDPR) applies to QR code systems that collect, process, or store personal data of EU residents — primarily through dynamic QR code scan analytics.

When GDPR Applies

GDPR is triggered when a QR code system collects personal data — any information relating to an identifiable individual:

• IP addresses: Collected on every dynamic QR code scan
• Location data: Derived from IP geolocation
• Device identifiers: User-Agent strings, cookies, fingerprints
• Behavioural data: Scan patterns, time, frequency

Static QR codes that encode data directly (no redirect server) do not trigger GDPR unless the landing page collects personal data.

Key GDPR Requirements

Lawful basis: You need a legal basis for processing scan data. Options: - Legitimate interest (analytics for campaign improvement) - Consent (user explicitly agrees to tracking)

Transparency: Inform users that scanning involves data collection. Include QR code tracking in your privacy policy.

Data minimisation: Collect only necessary data. Do you need IP addresses, or are aggregate scan counts sufficient?

Retention limits: Define how long scan data is stored. Delete after the campaign ends or after a fixed period.

Data subject rights: Users can request access to, correction of, or deletion of their scan data.

Practical Compliance Steps

1. Update privacy policy to mention QR code scan tracking
2. Minimise data collection: Use aggregate analytics when individual tracking is not needed
3. Set retention periods: Auto-delete scan data after 90-180 days
4. Anonymise where possible: Strip IP addresses after geolocation lookup
5. Respond to data requests: Have a process for handling DSAR (Data Subject Access Requests)

QR Code Tracking Without Personal Data

It is possible to track QR code performance without collecting personal data:

• Count total scans server-side without storing individual records
• Use first-party analytics with IP anonymisation
• Aggregate location data to city level without storing individual IPs
• Avoid cookies and device fingerprinting

Key Takeaways

• GDPR applies to dynamic QR code scan data that includes personal data
• IP addresses, device info, and location data are personal data under GDPR
• Static QR codes without redirect servers have minimal GDPR implications
• Minimise data collection and set retention limits for compliance
• Anonymised aggregate analytics can provide insights without personal data
