By Nandita Bose LAS VEGAS (Reuters) - Samsung Electronics Co's new mobile payment service Samsung Pay has enjoyed strong repeat usage among U.S. consumers with an average of eight transactions per user, the world's top smartphone maker said on Tuesday. Samsung Pay, which rivals mobile wallets like Apple Inc's Apple Pay and Google's Android Pay, allows consumers to pay at retail locations using their smartphones. Samsung's mobile wallet offers wide coverage of payment terminals where it can be used, and this is its biggest advantage, the company said at the Money 20/20 payments conference in Las Vegas.
