1.1 System Advantage
From the point of data collection, radio frequency
identification system completely resembles bar code system. In
the course of data collection, bar code system adopts one-way
communication, i.e., bar code sensor (reader) reads information
from bar code in non-touch way. During such information
flowing, bar code is totally in a passive and subordinate
position and the communication is one-way, i.e., information is
transmitted to bar code sensor from bar code tag.
The shortcoming of bar code system is that, if damaged,
polluted, damped or located inside an article, the bar code
couldn’t acquire data because the reading range of sensor is too
short.
Data collection system composed of XCRF-500 reader series
and their compatible electronic tags, fundamentally overcomes
the above shortcoming of bar code system. The communication
between reader and tag is two-way, in which the tag makes
