Target and Walmart have joined in the development of yet another mobile payment system, insides gave out on Thursday. The two were said by Wall Street Journal's contacts to now be part of a group with about 24 member store chains hoping to create a standard that, though not directly named, would use NFC. Consulting firm BetterBuyDesign's Steve Mott corroborated the plan by revealing its involvement in the project, with word that big chains as well as drugstores, fast food restaurants, and vending machine firms were involved.
