HouseTab, a new mobile application that combines mobile payments with its own social network, has officially launched in New York City and Montauk in Long Island. Some 20 bars and restaurants in Manhattan, Brooklyn, and Montauk initially are participating in the service, according to a press release.

Users check-in to their favorite bar or restaurant and when they’re ready to leave, either request their check and pay or tap the "Get Up and Go" button, which is linked to a payment card.

HouseTab has also created its own social network, allowing users to see where friends are checked-in, chat with them in real-time and send drinks/food to anyone on the network, at any time, according to the press release.

"Realizing that social engagement drives consumer adoption of mobile applications, we’ve incorporated a dynamic social network into our sophisticated mobile payment software,"  HouseTab CEO Andrew Tauber said in a press release. "HouseTabbers are not only using the app to pay their tabs safely and swiftly, but also to chat, gift food and drinks to friends and engage with their favorite nightlife venues. Our platform is powerful and multi-faceted."

HouseTab also offers rewards, discounts and deals to its frequent users, according to the press release. The company is using Braintree as its payment processor.

HouseTab is currently accepted at a growing list of New York hotspots, including in Manhattan: Anotheroom, Automatic Slims, Bakehouse, Bayard’s Ale House, Bubble Lounge, Circa Tabac, Local West, Nevada Smiths, Pergola, Rogue & Canon, The Room, The Otheroom, The Royal, The Winslow, Windsor Gansevoort Park and Windsor; in Brooklyn: Park Luncheonette; and in Montauk: the Surf Lodge

HouseTab is currently available in the iOS App Store and coming soon to Google Play.
