More that a dozen retailers including Best Buy, Walmart, Target and 7-Eleven have joined forces to form the Merchant Customer Exchange (MCX), a mobile-payments network that will compete with Google and Isis.
The retailers claim that they are better suited than mobile operators and OS developers to develop a successful mobile-payment system.
No launch date was given for the exchange, which was announced Wednesday, but development of MCXs mobile application is underway. It will be available through virtually any smartphone, according to a statement from the merchants. MCX is not yet saying which payment technologies it will use, but that information will be provided in the near future, according to a spokesman.
Like their competitors, the retailers plan to combine their mobile wallet with targeted offers and promotions that will be available through smartphones.
MCX will enter an increasingly crowded U.S. market for mobile payments using Near-Field Communications (NFC) and other methods. The two main competitors for MCX are Google Wallet and Isis, which is backed by AT&T Mobility, T-Mobile USA and Verizon Wireless.
Google Wallet was launched last year and can be used at over 140,000 merchants where MasterCard PayPass is accepted. To get the wallet, users need a compatible phone such as the Galaxy Nexus on Sprint, AT&T or T-Mobile or the Samsung Galaxy S III also on Sprint.
Recently, Google launched a cloud version of its mobile-wallet application and also added new security features to the system.
Google's rollout has had a few hiccups. Earlier this year, it suspended the prepaid capabilities on credit cards linked to its mobile wallet after a security flaw was exposed.
Isis, meanwhile, hasn't launched its mobile wallet yet. It has said that this summer, consumers in Austin, Texas, and Salt Lake City, Utah, will be able to start using the service.
HTC, LG, Motorola Mobility, Reserach In Motion, Samsung Electronics and Sony have all stated that they will offer smartphones compatible with Isis.
All of the companies pushing mobile payments are competing for a big market. The scale of global mobile-payment transactions is expected to rise nearly fourfold over the next five years to more than US$1.3 trillion, according to market research company Juniper Research.
