As President Obama makes his historic visit to Cuba this week, online payments giant PayPal says it’s starting to bring its business to Cuba.

The effort is part of a deluge of interest by U.S. companies in Cuba including airlines, hotels and other tourist interests following the loosening of trade restrictions. PayPal CEO Dan Schulman, who is visiting Cuba this week along with President Obama, U.S. Secretary of Commerce Penny Pritzker, and many other CEOs, said that PayPal pypl would start allowing money transfers to and from Cuba later this year.

Xoom xoom , founded in 2001, lets people send money, pay bills, and reload mobile phones from the United States to 37 countries. It is used widely by immigrants who send some of their earnings to family members back home. PayPal acquired Xoom in 2015 for $890 million.

Schulman said the opportunity for expansion is huge in Cuba, where $2 billion in cash is sent from the U.S. to Cuba annually. These U.S. remittances serve as 3% of Cuban GDP, he added. Because Xoom allows these remittances to take place digitally and via people’s phones, transferring money will be much easier, Schulman explained further.

Western Union wu , a competitor to Xoom and the world’s largest money transfer company, also said it would start operating in Cuba this year.

PayPal isn’t the first payments technology company to start expanding business into Cuba. Payments upstart Stripe announced last week that it is starting to help Cuban entrepreneurs set up U.S. businesses.
