48 | APPENDIX D: CLASS 1 VS. CLASS 2 LASER SCANNERS
application is likely to require more demanding scanning capabilities, the Class 2 laser
provides the assurance of maximum scanning performance.
Note: People who use portable computers to gather and manage data at the point of
activity are typically very quick to learn how to use a laser bar code scanner and realize the
resulting gains in productivity. They are easily discouraged, however, if time and effort are
required to obtain a successful scan – thus the decline in popularity of the much less
expensive bar code contact wands seen at most retail checkout counters during the 1980’s.
The higher cost of the Class 2 version of the CF RFID Reader-Scan Card is easily justified if
the application requires higher scanning performance.
