# vCard QR code compliance guide: GDPR, healthcare, finance, and legal controls

> Practical compliance guide for digital contact cards: legal basis, consent, retention, and industry-specific controls for GDPR, healthcare, finance, and legal teams.

## Short answer

A vCard QR code can be compliant, but only if you treat contact sharing as data processing and implement clear legal basis, purpose limits, access controls, retention rules, and audit trails.

## How it works

When someone scans a contact card QR code, two data flows are involved:

1. **Profile data** in the card itself (name, role, email, phone, company)
2. **Interaction data** from the scan (time, device, rough location, referrer)

Compliance depends on collecting only what you need, documenting why you need it, and giving users the controls required by applicable law.

## Core compliance checklist

Use this baseline across industries:

1. **Define legal basis** per use case (contract, legitimate interest, or consent)
2. **Publish a clear privacy notice** for contact-card and scan analytics processing
3. **Minimize fields** to business-necessary data only
4. **Set retention windows** for both card data and scan logs
5. **Implement role-based access** for who can export or view scan-level data
6. **Log access and changes** for auditability
7. **Add DSAR handling** (access, correction, deletion, export)
8. **Control cross-border transfers** with approved mechanisms

## Industry-specific controls

### Healthcare

- Keep contact-card tooling separated from systems containing PHI
- Do not include patient-specific details in contact-card fields
- Use stricter admin permissions and audit logs for exports

### Financial services

- Enforce message and record-retention policies in line with firm obligations
- Restrict broad data exports and require approval for external sharing
- Keep an evidence trail for compliance review and supervision

### Legal

- Avoid exposing client identifiers in profile fields
- Apply strict least-privilege access to contact and interaction history
- Maintain defensible records for confidentiality and conflict procedures

## Limits and caveats

- A compliant setup in one jurisdiction is not automatically compliant globally.
- Consent is not always the correct legal basis; use it only where required.
- QR scan analytics are often pseudonymous, but still regulated personal data in many regimes.

## Implementation pattern in Linkbreakers

- Use role-based workspaces to separate teams and limit access
- Store only required fields in contact cards
- Define retention and deletion procedures in internal policy
- Route legal/privacy requests to a documented DSAR workflow

## Frequently asked questions

**Do I always need explicit consent for a vCard QR code?**
No. In many cases, another legal basis may apply. The correct basis depends on purpose and jurisdiction.

**Is scan metadata personal data?**
Often yes, especially when it can be linked to an individual directly or indirectly.

**What is the minimum policy set I need?**
Privacy notice, retention policy, access control policy, and DSAR process.
