NEW technology is being developed at The Registry nightclub to help identify under-age drinkers and troublemakers.
Staff at the Bruton Way club hope to roll out the iTag system across Gloucester's nightspots and the police.
It is the next stage of the city pub-watch scheme and will allow clubs and bars to notify each other of people banned from city premises.
A smart phone app and key fob will show identification details to door-staff on entry, including a photo and the person's age using Quick Response technology. The QR codes are similar to bar codes, invented by Toyota in Japan to help track vehicles.
An individual pin number will also allow staff to access a drinker's details.
Information stored on the system could also show any medical conditions of drinkers such as epilepsy or asthma, so staff can respond with adequate first aid should a medical emergency arise.
Developers at the club hope the service will be free to use and could be tested-out in venues next year.
