Puerto Rico's biggest commercial bank will connect local merchants to global travelers, thanks to a new partnership with Discover Card. Banco Popular de Puerto Rico signed an agreement with Discover Financial Services to enable Discover Card acceptance at tens of thousands of merchants on the island.

In a statement to CNBC.com, representatives from both companies cheered the impact the new agreement would have for tourism and the island economy. Discover spokesperson Gerry Wagner said, "Cardmembers will be able to use their cards wherever they shop in Puerto Rico, allowing them even more opportunities to reap the great rewards offered by Discover."

The deal extends card acceptance to Diners Club members, adding over 20,000 eligible merchant locations, including hotels and restaurants throughout Puerto Rico. Banco Popular spokesperson Fabio Garcia notes that more than a million visitors per year would enjoy additional convenience by using their preferred credit cards while visiting Puerto Rico for business or pleasure.
