POS terminal to ring up a transaction, while other locations will allow the phone to be "swiped" against the side of the terminal as though you were swiping your credit card.
This explains the commercials for the service that show shopkeepers surprised to see Samsung Pay ringing up a transaction; that includes the new one starring Cosby whistle-blower Hannibal Buress, who uses Samsung Pay to take care of a sandwich he ordered from New York's iconic Katz Deli.
In an effort to get more subscribers to use the service, Samsung is offering consumers a free Samsung Level U wireless headset for merely adding their first card to the service. To qualify for the free headset, open Samsung Pay on your Samsung Galaxy S6, Samsung Galaxy S6 edge, Samsung Galaxy S6 edge+ and Samsung Galaxy Note 5. Activate an account using your Samsung Account ID over a participating carrier.
Next, you register a qualifying credit card before February 22nd. Once that is done, go to the "More" menu on the Samsung Pay app. Click on Samsung Pay Card Registration Offer. Agree to the terms and conditions to receive a code that you can use on Samsung.com to receive a black Samsung Level U Wireless Headphone (valued at $69.99) for free. Only 20,000 freebies are being offered, so once they are all gone, the deal is over. The code must be redeemed before March 15th, or before supplies last, so we wouldn't waste any time before taking Samsung up on this deal.
