SCANNERS

1-D BT Wireless Pen Scanner There are three main types of Barcode Scanners. They are: 1. Wireless / Tethered Scanners. 2. Integrated Barcode Scanner PDAs 3. Compact Flash (CF) and Secure Digital (SD) Scanners Wireless / Tethered Scanners Scanners that are connected (wirelessly or through cable) to a main computer. The operational range of these scanners is limited to the length of the cable or the strength of the wireless signal. Because of the limitation in range, these scanners are ideal for areas where a laptop or desktop computer is nearby.

Integrated Barcode Scanner PDAs

PDAs that have 1D or 2D barcode scanners built into them. They are simply a barcode scanner and a fully operating computer system built in one. These PDA Scanners have a choice of Laser, CCD or Imager Scanners, which are capable of scanning both 1D and 2D barcode labels. They are usually very rugged, have a long battery life, and are very mobile. San Dimas Technology has been evaluating PDAs in their Mobile Computing Project. More information on PDAs can be found on the following Forest Service Intranet webpage: http://fsweb/programs/im/fy03/ppc/ppc.shtml

Compact Flash and Secure Digital Card Scanners

These scanners utilize the Input/Output (I/O) card slots on the PDA. They can transform smaller, commercial grade PDAs such as an iPAQ or Dell Axim into a laser barcode scanner. These units are small, lightweight, and very portable. However they are usually equipped with lesser power Class I lasers which shortens the maximum distance at which the barcode can be scanned.
