In the new year, Croatia will become the latest country to join the Eurozone and the Schengen area, a move that European Commission president Ursula von der Leyen says makes the European Union stronger."It’s good to have some cash on you because the banking system will be in transition over the weekend,” Boris Vujčić, the governor of the Croatian National Bank, warned.“Consequently, neither cards nor internet banking will be operational, so it is good to have some cash just in case.On 2 January, everything should be functioning normally.”Croatia will also become the first country to join the Schengen zone in 11 years.The move will allow people to travel freely between it and EU member countries without border controls."
