Going through the supermarket checkout counter the other day reminded me of the KitKat advertisement on tv. Remember the guy who uses his teeth as a barcode reader? That ad cracks me up every time. I'll say he is as good as the Symbol LS2208 bar code reader I saw online.
I remember when barcode was first introduced here in Malaysia, companies were scrambling to have their staff trained to be able to use the new equipment setup. That is many years ago and now barcoding is part of our life.
