Another problem with the new European border system: a passenger detained by mistake

A new flaw has emerged in the European Union's new border management system, which recently caused complications for a British woman attempting to travel back home from Romania. The incident highlights ongoing concerns over the reliability of the Entry Exit System (EES), designed to streamline Schengen zone crossings through automated data checks. According to reports, the woman was detained, questioned, and accused of illegal residence after the system mistakenly linked her identity with that of her identical twin sister. The EES, launched earlier this year, has already faced criticism from nine member states who warned the European Commission’s internal affairs commissioner, Magnus Brunner, about “significant issues” encountered during its initial months of operation. Now, additional problems have surfaced, particularly regarding the system’s ability to distinguish between identical twins. A report by the Brussels-based outlet Politico detailed how the British woman attempted to fly back to the UK from Romania at the end of May but was stopped by border police. She was accused of residing illegally in the Schengen area because the system failed to correctly record her departure from Amsterdam in April 2026. However, the woman had not been in Amsterdam at all, her identical twin had been there instead. When she tried to explain the situation, she was initially suspected of having lent her passport to someone else. Her twin, meanwhile, had never set foot in Romania and remained in the UK. It appears the EES system matched the woman based on facial recognition, along with likely matching surnames, dates of birth, and nationality. However, it did not account for differences such as fingerprint records or the distinct passport numbers each twin holds. Despite being allowed onto the plane eventually, the woman expressed concern over future travel if similar issues arise again. Niovi Vavoula, a cybersecurity professor at the University of Luxembourg, suggested the problem stemmed from poor implementation of the EES by member states. She noted that the sister’s exit from Amsterdam might have been improperly recorded, possibly due to the system still being in its early stages of deployment. The woman’s trip concluded on April 12, while the EES system began operations on April 10. Vavoula also criticized the Romanian border authorities for their approach. According to EES guidelines, passengers should not be identified solely by facial recognition but must undergo verification using fingerprints and passport numbers. She pointed out that the authorities appeared overly reliant on facial recognition, neglecting other critical identification methods. This behavior, she explained, reflects a cognitive bias known as anchoring, placing too much trust in the first piece of evidence and disregarding other factors. In response to inquiries from journalists, the European Commission stated they would not comment on individual cases but emphasized that member states are responsible for entering data into the EES. They added that travelers whose data is processed incorrectly can request corrections and updates to their personal information directly from the relevant national authorities, either at the border or through local offices. The incident underscores the challenges of implementing complex digital systems across multiple jurisdictions. While the EES aims to enhance security and efficiency, these early hiccups raise questions about its readiness and the preparedness of national agencies to handle its intricacies. As the system continues to roll out, further scrutiny will be necessary to ensure it functions as intended without compromising the rights and experiences of travelers.
