It may sound like something out of Robocop, but police in China are now using glasses with built-in facial recognition software to catch wanted suspects.
Officers are using them at the Zhengzhou East high-speed rail station as many people are currently travelling to visit family for the Lunar New Year.
So far the glasses have enabled authorities to locate seven hit-and-run or human trafficking suspects as well as 26 people allegedly connected to identity fraud.
The glasses are connected to a tablet and are able to match faces to a database of suspects, The South China Morning Post reported.
The system is able to create what is known as a faceprint, by measuring aspects of a face to create a code unique to that person.
Despite the apparent success, recognition software can have a mistake rate of 0.8%, which means for every 1000 scans eight people could be identified wrongly.
Police officers are stationed at four entrances of the station, according to local media.
It is thought around 70,000 to 120,000 people pass through the station everyday.
