We were switching a retailer from software from another company recently when we encountered old hand-held scanners at the counter. While they scan barcodes, they are slow and somewhat inflexible. For many years we have supplied our customers with omni-directional laser scanners and the photo shows the value of these scanners. You can see multiple laser lines shooting from the scanner. This makes scanning barcodes faster, easier and more accurate.
While our core focus is as a software company, often our advice with hardware helps retailers save time and money and at the retail counter, time is money.
