Clubscan
Clubscan was an ID card scanning system invented by Tamlyn Thompson in 2005. It took scanned images of nightclub pateons' ID documents and stored their personal details, for the purpose of age verification, identifying barred members and identifying individuals to the authorities in the case of criminal incidents.
Clubscan is now discontinued and replaced by SCAN NET (the Safer Clubbing At Night Network) and serving over 1200 connected venues in the UK and Australia alone.
