You should check out Pop! Technology just to view their cool website and demos, including one on YouTube. Never have I seen animation used so effectively to sell a product, except of course in video games.
Founded in 2004 by Jon Cameron, Pop! Technology holds a broad methods patent on integrating bar codes with thermal indicators. What, you say? Aren't all the RFID guys running around trying to monitor product temperature variations with complex chip/reader technologies? Yes, they are, but how about a simpler solution, like one integrated with our old friend the bar code. The Pop! Technology solution allows you to attach a thermally sensitive bar code that can be read by anyone's UPC readers and have the data reported out to IRI and Nielsen.
So who cares? It turns out that a lot of beverage manufacturers do. Before Pop! Technology, companies just got total beverage sales by store, not sales by on-shelf(warm) versus cold vault. It turns out that beverage marketers care a lot about how to position their product in stores and Pop! Technology thermally sensitive bar codes can tell them which products were sold warm and which cold.
The same is true for many pharmacy products, which must be kept in certain temperature ranges to avoid affecting the efficacy of the drug. Pop!'s bar codes can report when those parameters have been violated in the supply chain and where the violation happened, assuming the products are scanned during the shipping process. The data can then be reported back to the shipper via existing shipment tracing capabilities. UPS, for example, can support such thermal reporting today as part of its overall shipment tracking process.
In addition, Pop! has developed an anti-counterfeiting, anti diverting solution for the pharmaceutical industry, in partnership with BTI. The solution is much simpler than the current ePedigree technology, using a 5-way check which can be done at any point in the supply chain, even at the consumer level.
From a food safety perspective, the technology has obvious appeal. Being able to track temperatures in the cold chain is a big deal to consumer wanting guarantees about how their food has been handled. Unfortunately, one could strip off the "bad" (high temperature reading) bar code and put another one on, but not if the only labels were available at the producer.
Pop! Technology is still operating in a pseudo-stealth mode, since many of their major clients want the technology to be a well-kept secret (read: competitive advantage). However, they have not signed any exclusive deal, so you can get in on the action if interested.
