1.ScreeningArt. 35(1), (3); WP248; § 7150
- Sensitive data or data of a highly personal nature (WP248 4)
- Innovative use of new technology, such as face or fingerprint recognition for entry (WP248 8)
- Processing sensitive personal information (other than employee data used only for pay, benefits, work authorisation, accommodation or wage reporting) (§ 7150(b)(2))
- GDPR data protection impact assessment
- expected: 2 of the 9 WP29 criteria; two or more call for a DPIA in most cases.
- California risk assessment
- required: § 7150(b)(2); conduct it before the processing starts (§ 7150(a)).
2.Description of the processingArt. 35(7)(a); § 7152(a)(1)–(3)
- Purpose
- Let members enter a gym by looking at the turnstile camera instead of carrying a key fob, so a lost or lent fob no longer lets a non-member in.
- Legitimate interest
- Not relied on: the lawful basis is the member's explicit consent.
- Personal data
- Face template (a numeric vector, not a photo)
- Member ID
- Check-in time and gym
- Minimum needed
- The template, member ID and check-in time. No photo is stored after enrolment; no camera footage is kept.
- People
- About 21,000 members across 9 gyms
- Method and sources
- Collected at the front desk when a member opts in; the template is matched on the turnstile unit in each gym.
- Retention
- Template: until the member opts out or cancels, deleted within 30 days. Check-in log: 13 months.
- Interaction
- In person at the front desk and the turnstile; members manage their choice in the gym app.
- What people are told
- Opt-in screen at enrolment, a sign at each turnstile, and the privacy policy's biometric section.
- Recipients
- Turnstile vendor (service provider / processor): hosts the matching software
- Cloud host (sub-processor): encrypted backups only
3.Necessity, proportionality and benefitsArt. 35(7)(b); § 7152(a)(2), (4)
- The purpose is specified, explicit and legitimate
- yes: Entry control only; the contract with the vendor bars any other use.
- A lawful basis is identified
- yes: Explicit consent under Art. 9(2)(a); a fob or app QR code stays available at the same price.
- Only the data the purpose needs is collected
- yes: No photo kept after enrolment.
- Each category has a retention period or criteria
- yes: Deleted within 30 days of opt-out or cancellation.
- People are told about the processing, and how
- partly: Turnstile signs not yet printed.
- Access, erasure and objection requests can be met
- yes: Opt-out in the app deletes the template.
- Vendors that touch the data are named and under contract
- yes: Vendor DPA signed; one sub-processor listed.
- Transfers outside the EEA have a transfer tool
- partly: Vendor support team in the US: transfer tool to confirm.
- Benefits
- Members: no fob to forget or lose. Business: fob sharing ends and replacement fobs stop costing staff time.
4.Risks and the measures against themArt. 35(7)(c)–(d); § 7152(a)(5)–(6)
- 1.
Face templates stolen from the vendor's systems
Unauthorised access, use, change, loss or disclosure; before 2×4 high; after 1×4 medium
Cause: A breach at the turnstile vendor or its cloud host
Measures: Templates encrypted and kept on the gym's own turnstile unit; backups encrypted; vendor breach notice within 24 hours in the DPA.
- 2.
Members feel they have to enrol
Coerced into the processing; before 3×2 medium; after 1×2 low
Cause: Front-desk staff pushing the faster lane
Measures: Fob and app QR code kept at the same price; staff script says it is optional.
- 3.
Templates kept after a member leaves
Loss of control over their information; before 3×2 medium; after 1×2 low
Cause: Cancellation not passed to the turnstile system
Measures: Cancellation triggers deletion; monthly check of templates against active members.
- 4.
A member is wrongly refused at the turnstile
Psychological harm; before 2×1 low; after 2×1 low
Cause: A failed match in poor light or after a change in appearance
Measures: Staff override at the desk; member can re-enrol in a minute.
- 5.
Check-in data reused to track members
Loss of control over their information; before 2×3 medium; after 1×3 low
Cause: Someone wants usage reports per member
Measures: Check-in log limited to time and gym; the vendor contract bars other uses.
| Severity | Likelihood 1, remote | Likelihood 2, possible | Likelihood 3, likely | Likelihood 4, almost certain |

5.ConsultationArt. 35(2), (9); § 7151; § 7152(a)(8)
