For Retailers, the Times, They Are a-Changin'

I don't know how Apple is implementing this solution, but this concept cries out for RFID, because retailers require real-time data to execute the operation efficiently. First, it's important to know precisely what's in stock within each store, and to be able to replenish effectively. For items not in stock, RFID could be used to track their movements, and ensure that customers are alerted when goods arrive at the store. If employees fail to scan bar codes, shoppers might not be notified for hours or days. With RFID, that process can be automated.

Apple might believe that it can execute effectively without RFID (we'll see if that's the case), but the company only has 300 stores, with a fairly limited number of items in stock. Macy's, on the other hand, operates 850 stores and sells many more items, while Wal-Mart has 4,000 stores and many more stock-keeping units (SKUs). The larger the chain, and the more items stocked, the harder it would be to execute on an omnichannel retail strategy without first implementing RFID.

Self-checkout really can work if RFID is used like an electronic article surveillance (EAS) system. If I paid for my new iPod using the system BGR described, the store's database could immediately be updated. When I walked out, the unique ID number associated with that item's RFID tag would be read, and the system would indicate it as having been paid for—or sound an alarm if I failed to do so.

Moreover, RFID can enable other cool innovations, such as interactive kiosks, magic mirrors and personal shoppers (see RFID for What? Enhancing the Customer Experience). And it's these types of innovations that are going to be required if retailers want to get people like me back in the stores.
