Samsung Pay will be a lot more useful in the US these coming months. According to the South Korean electronics maker, the mobile payment service is doing quite well in the country, but it still has a limited reach because it only supports cards issued by a handful of major banks. In the coming months, though, the app will start accepting cards from Chase, PNC Bank, TD Bank, SunTrust, Fifth Third Bank, Key Bank, Silicon Valley Bank, Security Service Federal Credit Union, Navy Federal Credit Union, Virginia Credit Union, Associated Bank, Randolph Brooks Federal Credit Union and People's United Bank. Have a Discover card? You have to wait a bit longer, but the payment facility will begin supporting it sometime in 2016.
