Well it looks like Nordstrom is one of those stores and judging from the photo above they have adopted the iPhone to be used as their POS device which not only allowed the salesperson from conducting a transaction with the device, but at the same time allow them to check whether they had a certain item in stock and all of this was done via the iPhone. Customers can apparently also choose how they want to receive their receipts and one of those ways was via e-mail.
It does seem like a novel idea but we’re guessing it’s only a matter of time before it starts catching on, especially in larger retail stores where the lines at the checkout counters get insanely long during the holiday seasons, so having salespersons roving about with a POS device could prove to be a way to start cutting down on those long lines and no more having to wait for a salesperson to run to the back of the store to check whether those pants come in your size.
