摘要: An adapter having an L-shaped housing is configured for removable attachment to a conventional PDA. The electrically coupled with the PDA and includes laser or other light source selectively emanate beam that can be modified into digital signal. signal received by photo detector on computer facilitating download of data from computer. also used as presentation pointer. further which positioned relative so reflected off bar code detector. then converted forwarded storage access corresponding information.
