LoopPay is expected to provide Synchrony Financial with special features and benefits for its cardholders and retail partners.

LoopPay recently introduced the LoopPay ChargeCase, which allows consumers to pay with their iPhone 5 or 5s at regular credit card swipe readers, while extending the phone's battery charge by up to 60%. It is the second product launched by LoopPay in four months, with several more products planned for market entry this year.

"These types of investments demonstrate our commitment to innovation and growth in the emerging payments space," said Margaret Keane, president and CEO of Synchrony Financial. "We are continuously exploring technologies to help our partners grow, while looking for additional options to deliver greater convenience and utility for our cardholders."

In a crowded mobile wallet marketplace, consumers are becoming increasingly interested in secure solutions to replace their physical wallets as merchant acceptance evolves. LoopPay technology enables existing point-of-sale infrastructure to accept contactless payments through mobile devices at the vast majority of retail merchants. Synchrony Financial views LoopPay as an opportunity to close this gap for its retail partners and their customers while offering an enhanced consumer experience and additional security features.
