In other words, if the bar code was not already scanned to the computer at the office, even though the wand could read the code, the computer could not make a match. In only a few short years, though, we have come from these passive wands to small, handheld computers that are completely interactive. They no longer require preset bar codes, because the handheld device can program the codes on-site with a simple scan. There is also no longer any need for pocket scanning cards to record data, because now the user selects appropriate data by touching the screen with a slim, pen-like stylus. All you have to do is scan the bar code and follow the menu screens to input the required information.
User friendliness is another area in which the bar coding companies have made a quantum leap.
The original programs were cumbersome and difficult to maneuver through. If you weren't computer literate, you had a big learning curve to overcome the intricacies of the program. This data is then communicated to the host computer either directly, over a phone line or even wirelessly. Even creating graphs and unique reports is easy with only a little training on the desktop software. As our customers request more information, we will be forced to find easier ways of collecting and reporting.
