European customers of Coinbase have been able to buy bitcoin and ethereum using debit and credit cards for a little over a year. Now, they can do it on mobile, too.

Strong numbers from the U.S. seem to support the move. Announcing the new functionality on the its blog, Coinbase noted that 40% of its credit and debit card purchases of digital currencies in the U.S. are coming from mobile devices. “Our mission at Coinbase is to create an open financial system for the world,” the post read, “and enabling easy access to digital currencies like bitcoin and ether in as many countries as possible gets us one step closer to that goal.”

Indeed. Coinbase last month added Australia, Canada, and Singapore to the list of countries where Coinbase customers can use payment cards to buy digital currencies. The company added support for ethereum earlier this year, and enabled PayPal and credit cards for bitcoin sales and purchases, respectively, in June. Coinbase launched the U.S. beta of its instant bitcoin purchase via debit card in March and expanded the service to all U.S. customers later in the spring.

Coinbase’s free mobile wallet works for both Android and iOS (in addition to online). Customers can create a digital wallet, connect a bank account, debit, or credit card, and then begin buying both bitcoin and ether on the Coinbase exchange.

Founded in 2012 and headquartered in San Francisco, California, Coinbase demonstrated its Instant Exchange technology at FinovateSpring 2014. The company has raised more than $117 million in funding, including a strategic investment of $10.5 million from Bank of Tokyo Mitsubishi UFJ in July. Coinbase has exchanged more than $4 billion in digital currency and served more than four million customers in 33 countries.
