Mobile or 'Wireless' Barcode Scanners as they are better known are indispensable when you
  need to collect data away from a PC. Mobility makes for ease of input and use, particularly on
  those occasions when extending the cord of the existing barcode scanner isn't possible or   practical. In such environments only wireless barcode scanning will do.

  Wireless ‘wedge’ scanners have 2 components, the scanner and the base station. The scanner   will communicate with the base station, and the base station will send the decoded barcode   information to the computer to which it is connected. Base stations connect to the computer the   same way wired scanners do, using a PS2, USB or RS232 connection.

  There are 2 types of wireless wedge scanners, and the difference being in how the scanner
  ‘ talks’ to the base station. This could be by frequency hopping algorhythm using the 14 channels   availiable in the 2.4ghz spectrum for wireless communication, or by BlueTooth protocol. Both are   similar in range and performance. The interesting thing about using BlueTooth communication is   that, generally, you can connect the scanner to any BlueTooth enabled receiver, and the ASCII text   will be sent to that device. Using this connection method, you can connect direct to another   BlueTooth device and by-pass the base station. Before purchasing for this reason, make sure
  that the scanner has a driver that will enable the host device to communicate. Most of the
  scanners Customark sell will work with PocketPC devices.

  If all this technical information has you confused, don't worry, you could always contact one of our   Helpdesk operators who would be happy to ‘walk you through’ and determine which is the right   model for your application.
