The "wand" is the simplest and least expensive input device available. It is durable and contains no moving parts. It must, however, come into contact with the bar code, which can handheldscanners and handheldscanners present a challenge. If a bar code must be read more than once, it may become smeared or damaged and, in essence, unreadable. Also, a wand is "human powered," which means it must be held at the proper angle and moved at the proper speed. For these reasons, a wand is the best choice when handheldscanners cost is the largest handheldscanners determining factor. The CCD, or "Charge Couple Device," is another common input device. A CCD is a very "aggressive" instrument, with a high ability to read bar codes quickly handheldscanners and easily. But it has two primary limitations. First, it has a short "read" range, and must be held no more than 1 to 3 inches handheldscanners from the bar code. We believe that due to the increasing number of programmable platforms, the increasing number of capable programmers, the increasing robustness of development tools, the increasing population on-line, the increasing bandwidth available to the average consumer, and the ease of web-based software distribution, independently developed programs, currently handheldscanners known as "shareware", will become the major force in task and platform specific retail software.
