While LoopPay's technology is widely accepted, right now you can only use it by purchasing one of its smartphone cases (starting at $16) or its $10 keychain module. The Samsung acquisition will likely remove that barrier, though. LoopPay's tech can actually be built right into phones, so don't be surprised if you see it being touted as one of the integral features of the upcoming Galaxy S6. That also gives it some major advantages over Google Wallet, which has struggled to take off because it's only compatible with certain Android phones and carriers. In fact, we may even see Samsung license LoopPay's technology out to other Android phone makers eventually. (Which makes us wonder why Google didn't snap up LoopPay first.) If Samsung plays its cards right, it may soon have an even more tempting mobile payments option for consumers than Apple Pay.
