The European Union's long-delayed digital border system is facing renewed scrutiny after an identical twin was mistakenly flagged as having overstayed in the Schengen area, exposing fresh concerns about the reliability of biometric border controls just months after the system's launch.
System Launched After Years of Delays
The Entry-Exit System (EES), introduced on April 10 after years of delays, was designed to modernise border management by replacing passport stamps with biometric records, including facial recognition and fingerprint scans. Instead, the rollout has been marked by technical glitches, lengthy queues, and growing questions over how effectively the technology is being implemented across member states.
Incident Involving British Traveller
The latest incident involved a British traveller returning to the United Kingdom from Cluj-Napoca, Romania, in late May. Romanian border officials questioned the woman for approximately 15 minutes after EES records appeared to show she had entered the Schengen Area through Amsterdam in April 2026 but had never officially exited. Authorities suspected she had overstayed her permitted time in the bloc.
However, the woman had never travelled to Amsterdam. Her identical twin sister had. Despite carrying different passports, having different first names, and possessing unique fingerprints, the two sisters share nearly identical facial features, surnames, dates of birth, and nationality. Those similarities appear to have contributed to the system confusing one sibling for the other.
Border officers reportedly initially suggested the woman had lent her passport to someone else before eventually allowing her to continue her journey.
Expert Analysis and Response
Cyber policy experts say the incident likely reflects a combination of early technical issues and operational mistakes rather than a failure of facial recognition technology alone. According to specialists familiar with the EES framework, border officers are required to verify travellers using multiple identifiers, including fingerprints and passport information, not facial recognition alone. The incident suggests established procedures may not have been fully followed during the verification process.
Following an internal review, the Romanian Border Police stated that the EES platform itself had functioned correctly but acknowledged that border staff had failed to follow the required operational procedures. Officials said the traveller's data was corrected manually and confirmed that additional training has since been provided to border personnel. The agency described the case as an isolated incident rather than evidence of broader system failures.
