EU's new automated border checks come with travellers warned they face delays. The European Union has introduced a new system of automated border checks, but it's already causing problems for travellers. The system uses artificial intelligence to scan documents and identify potential security risks, but it's not yet ready for widespread use. In fact, the UK's travel advice website has warned that travellers may face delays when using the new system. The EU hopes to roll out the automated border checks across all its member states, but for now, it's a slow process.
