If this is a question you are trying to seek answer to, I suggest head over to Cashier Live’s recently launched interactive microsite “Future of Retail”. New technologies like mobile advertising, in-store augmented reality, and cloud-based software are changing how retailers (big and small) sell to consumers. The microsite presents scenarios for Mobile coupons, Virtual mirrors, Welcome kiosk, Digital signage, Self-checkout, Email receipts, Store management, RFID tags and Purchase orders. For each scenario, there are Proof of Concepts which shows how the retailers are working or thinking about using these new technologies. For e.g. for Welcome Kiosk there is this cool Gap Welcome video from Minority Report.
