According to MacRumors, we can expect Apple to soon evolve retail beyond what it’s already done with its leading edge and clean store designs. The next step for Cupertino is allowing customers to make purchases in-store via the company’s free iOS app. An email you receive will be proof of the transaction and can be shown to store employees so they know the purchase has been made. Another source says the functionality is on its way November 3rd and will only be available to iPhone 4 and 4S users.
I would imagine the customer will just scan a bar code with the upgraded app and then confirm the purchase. Does this mean Apple will become a leader in mobile payments this week? Possibly. Moreover, how will the rest of the industry respond? Expect lots of noise from PayPal, Google and others very soon.
