A white armored van with the Loomis logo on the sides is parked next to the Poble Sec metro station in Barcelona. Its four flashing lights are on. No one is inside. A few minutes later, a pair of officers in black uniforms emerge from the metro entrance and head toward the vehicle, holding a bundle of cash collected by the metro ticket machine. Loomis is the company responsible for collecting and counting the cash generated daily by part of the Barcelona Metropolitan Transport (TMB) ATM network. It's also common to see its vans waiting in front of banks or large shopping centers.
