Technically, products can be tracked all the way to the customer’s home and into it. However, when Benetton planned to track products after the sale, with an eye on returns, it was met with customer resistance on grounds of privacy. This caused Benetton to delay plans for rolling out this idea. The other major hurdle to implementation is the price of the tags. Price/margin levels in most consumer packaged goods tags need to be low enough to be affordable at the individual product level. However, with Wal-Mart mandating tag application from its major suppliers, critical mass will be accomplished sooner rather than later. Beyond product-level tagging in retail channels, many other applications are already in place at case-level, and in higher-value goods such as automotive parts.
