At the Innovation Days Exhibition in Lisbon, developers were showing off new software designed to detect the causes of road accidents. The system uses photos taken at the scene of an accident, official reports and analysis of the road conditions to make a 3D computer recreation of the crash. The aim is to avoid wrangling over what – or who -might have caused any given accident.Immigration officers sometimes make mistakes but a new automatic system could reduce these errors. Electronic passports containing personal and biometric information are scanned at the first gate. Then the biometric information is double checked by a biomentric machine against the live passport holder and a central data base. If everything is ok the second gate opens. The check is complete. Accuracy and efficiency are improved. But best of all, this machine carries out these checks faster than a human immigration officer – and so could help reduce queues for travellers all over the world.
