ClassNet Terminal User Manual

or staff member going to each ClassNet Terminal and touching a
DataTag to the IDTag receptacle. The DataTag is then taken back to the
main office computer and inserted into a DataTag Homebase , where it is
read and stored to disk by ASP’s ClassNet DataTag Utility program.
As in the other download options, the administration staff can then run a
program to process the collected data.
Because there is no direct connection to the computer in this scenario, the
ClassNet Terminal’s clock is set using a special
TimeTag which is
configured using the ClassNet DataTag Utility .
See the section later in the manual for details on how to use the ClassNet
Terminal with DataTags.
Barcodes or IDTags?
The ClassNet Terminal reads both barcoded cards and IDTags.
Plastic barcoded cards are cheaper than IDTags, and (although it makes
them dearer) can be printed with text, logos, photographs, the student’s
name and signature, and can sometimes be used for other purposes (ie
library cards, or identity cards, etc). Plastic cards also wear out.
IDTags are smaller, more robust, more secure (they can’t be duplicated,
whereas a photocopy of a plastic card will scan as easily as the original),
and conveniently attach to a key-ring. However, they are significantly
more expensive.
