As an alternative to Danavation Technologies Inc, look to Pricer AB. It trades in Stockholm, but has customers world-wide, including Canadian Tire. Electronic shelf labels are a huge market - tying them in with supply change systems, every major retailer is going to be rolling them out within a couple years. It may be that Danavation becomes the industry-leader, but I think you're missing out if you only invest in them: don't make an all-or-nothing bet on the ESL market.

A little scary too - from Wikipedia: Third generation: Geo-location and product finder
The current generation of ESL utilize e-paper display and radio communication, though with the addition of integration with existing retail applications such as electronic article surveillance, digital signage, and people counter. With the integration to various people counter devices, whether it is powered through video counting technology or Bluetooth beacons, it will be able to track the visitors that are within the store based on the consumers' movement. Retailers are able to upload a floor plan of the sales floor into the label management software. Consumers are tracked through the people counting device or their Bluetooth devices to determine their positioning within the store at all times.
Anyone else remember Minority Report and their personalized ads?
