barcodes - I know the initial time expenditure does not look good to your immediate needs, in as much as the training and potential equipment additions to your business. But the long term benefits should far outweigh any time spent upfront in the process, while digital photos will more than likely continually create new and unique opportunities to have to work on process modifications as products change in any number of unanticipated ways down the road.

If you take a week or so now for development / training, you can cut your handling time over the long haul immeasurably, saving you time and money. And besides, I have never bought something and had to hold it up for a photograph! I don't think you want that kind of marketing word of mouth, do you?

Good luck
