> European merchants who want to take advantage of Braintree to accept online and mobile payments can now apply for an account online.

I feel this is a common misconception that accepting credit cards in Europe equals having a good online payment option in Europe. It just means you've half implemented a payment system in Europe since a lot of people here use Debit cards [1]. Besides that there are also other common payments solution like direct bank to bank online Giro systems for example iDeal in the Netherlands or Giropay in Germany.
