8.1.9. RFID Hardware
Radio frequency identification (RFID) is an automatic identification method, relying on
storing and retrieving data using devices called RFID tags or transponders.
An RFID tag is an object that can be applied to or incorporated into a product, animal, or
person for the purpose of identification using radio waves, some tags can be read from
several meters away and beyond the line of sight of the reader
There are many types of RFID tags and these can be either passive or active devices, we
will however concentrate on two tags the Key fob and the Wristband
The MultiWeigher 3000 software can assign an operator a Key fob
as their unique identification for automatic logging on and logging
off the system. The key fob is a passive device and does not store
any personal information, it simply transmits a 256bit encrypted
number when it is in proximity to the reader house in side the
weighing scale.
