I've seen some of those tubes at a Carrefour or Mercadona supermarket back in 2005 or something, in Spain. When they had too much many at the cash register, they sent the money to their backoffice. Super cool! Nowadays in Germany they just take the cash register part with the money out and walk to the Tresor room, or have sort of wallets and a colleague delivers the money to there. Example taken from a Kaufland.
