UK to scan asylum seekers’ faces for age checks despite flawed tech

The UK Home Office announced on 20 June that a facial‑age verification system will be installed at Heathrow and Gatwick from July 2026. The system, built by biometric firm Veridex, estimates age from a single selfie and flags anyone under 18 for further interview. A trial of 2,200 arrivals between March and May 2026 produced a 30 % false‑positive rate for minors and a 12 % false‑negative rate for adults, prompting internal warnings that the technology is not ready for operational use [Ars Technica].

── What happened ──

The rollout follows a Home Office directive requiring age screening within five minutes of arrival. Veridex’s version 3.2 algorithm claims a mean absolute error of 1.8 years, but pilot data showed a median error of 2.6 years for those under 18. The government cited a 2025 parliamentary briefing on rising fraudulent age claims as justification. The contract allows the vendor to share facial images with UK Border Force analytics platforms, though storage policies were not disclosed [Ars Technica].

── Why it matters ──

• Legal risk – Processing biometric data without explicit consent breaches GDPR and the UK Data Protection Act, exposing the Home Office to fines up to £17.5 million. Internal legal counsel flagged a high probability of non‑compliance in a June 2026 memo.
• Engineering credibility – Error rates above 30 % erode confidence in AI‑driven biometric tools and may delay future procurement cycles as auditors demand independent validation.
• International precedent – If the UK proceeds, other European nations may adopt similar flawed checks, embedding privacy‑invasive practices before robust standards exist.

── Editor’s take ──

Deploying a system known to misclassify minors trades civil liberties for political optics. Misclassification could send children to detention or deny protection, while damaging the UK’s compliance record and public trust in biometric technology.
