Samsung Pay offers a pretty cool take on mobile payments, but it only works if your bank supports the app. Now Samsung is adding another big U.S. bank to its ranks as the company continues to expand its service. It’s also offering a gift card in celebration of the expansion.

Starting on Monday, Samsung Pay will work with Chase-issued Visa credit and debit cards. If you’re a Chase customer, you should be able to add your card to the app, assuming you own one of four devices: the Galaxy S6, the Galaxy S6 edge, the Galaxy S6 edge Plus or the Galaxy Note 5.

You don’t need to use Chase to take advantage of a new offer, though. Samsung is offering a $50 gift card to Best Buy if you activate an eligible card, including American Express, Bank of America, Citibank, U.S. Bank or Chase.

Samsung’s mobile payment app uses Magnetic Secure Transmission (MST) technology, making it possible to pay with your phone even if there’s no NFC reader in sight. Instead, your device can communicate with a regular swipe reader, essentially tricking it into thinking you’ve used a regular credit or debit card.
