Ask HN: what can be done with barcodes?
What would you like to see done with barcodes? How can they be leveraged to make shopping easier, more efficient, more fun?
convince the major (big box) retailers to provide an access point, so that you can price scan with your smart phone, instead of having to hunt all over the store for a working scanner. places like walmart, target, kmart, bestbuy, etc, etc could all benefit from this.
