I agree, this is just a Cuecat + wifi, which is actually great. Scanning barcodes is really not that much fun, and can get frustrating because of moisture, wear or just plain hard to find barcodes. An RFID system could avoid much of this. That being said if it took them 5 years to figure out the economic model for delivery, I imagine cheap (free) barcodes was a major factor in this decision.
