There already exists a company called Teller in Europe which is dealing with payment solutions.
> Nets is split up in two divisions: Nets, which manages the Danish market, and Teller, which handles all international markets. This means that Nets processes all Dankort transactions, while Teller processes all transactions by international cards.
