Hop ensures responsible serving and responsible drinking. All consumers’ identifications are validated upon entry by a helpful Tapster, then signed up with Hop’s seamless POS system. Using advanced facial recognition technology, a Hopper’s sign-up image and ID is compared and evaluated with their current appearance every time they tap to refill. Think again, drunks and identity thieves. All consumers have an alcohol limit per visit and will be refused service by all Hop stops in the area if they appear intoxicated.
