Apple’s mobile payments service could expand to additional European countries soon, including Hungary and Luxembourg, shortly after arriving in Iceland earlier in the month.

MacRumors has managed to spot server changes Apple makes ahead of expanding Apple Pay to new regions. “The service could launch in both countries within days,” the site speculated.

Luxembourg, a small landlocked country in western Europe, has a population of about 600,000 people. Its capital, Luxembourg City, is one of the three official capitals of the European Union. Hungary is a Central European country with about ten million inhabitants, making it a medium-sized member state of the European Union.

Aside from Iceland, the service recently launched in Austria, Czech Republic and Saudi Arabia. Later this year, it should hit Portugal and several Eastern European markets, like Estonia, Greece, Slovakia, Slovenia and Romania, as per N26, Zive.sk, ING Bank and online banks.

The service debuted in the US back in October 2014.

As of recently, Apple Pay works with several British government services, including the country’s Global Entry Service which allows UK citizens to get expedited entry to the US.

Apple has said it wants to bring Apple Pay to 40 countries before the end of 2019.
