3. Data Minimization
- Collect only necessary booking information
- Avoid "nice to have" data fields
- Regular review of data collection practices
4. Accuracy
- Keep booking data up to date
- Allow customers to correct their information

Data Subject Rights Implementation
Your booking system must support these customer rights:

Legal Basis for Booking Data Processing
Choosing the Right Legal Basis
Different types of booking data require different legal justifications:
| Data Type | Legal Basis | Reasoning | Example |
|---|---|---|---|

| Payment information | Contract performance | Required for transaction | Credit card, billing address |
| Health information | Explicit consent | Special category data | Medical history, allergies |
| Marketing preferences | Consent | Optional promotional activity | Email marketing, SMS offers |
| Financial records | Legal obligation | Tax and accounting requirements | Invoice data, transaction records |
Consent Management Best Practices
When consent is required, it must be:
- Freely given: No forced bundling with service access
- Specific: Clear about each purpose
- Informed: Customer understands what they're agreeing to
- Unambiguous: Clear positive action required
- Withdrawable: Easy opt-out process
Data Protection Impact Assessment (DPIA)
When DPIA is Required
Booking systems typically need DPIA for:
- Health appointment booking: Processing medical information
- Automated decision-making: AI-powered scheduling or pricing
- Large-scale personal data processing: Systems with 10,000+ customers
- Systematic monitoring: Tracking customer behavior
DPIA Process for Booking Systems
Step 1: Describe the Processing
- Map all personal data collected during booking
- Document data flows and storage locations
- Identify all parties with data access
- Define retention periods for each data type
Step 2: Assess Necessity and Proportionality
- Justify each data field collected
- Consider less invasive alternatives
- Evaluate data minimization opportunities
- Document legitimate interests or legal obligations
Step 3: Identify and Assess Privacy Risks
- Analyze potential data breaches and their impact
- Consider discrimination or exclusion risks
- Evaluate surveillance and profiling concerns
- Assess third-party processing risks
Step 4: Identify Measures to Mitigate Risks
- Implement technical safeguards (encryption, access controls)
- Establish organizational measures (staff training, policies)
- Plan incident response procedures
- Create ongoing monitoring processes
