6.4. Tag Access Screen
After acknowledging a tag, the Speedway reader may choose to access it. Under the
Tag Access
menu, a pull down menu
provides five command Actions: Read
,
Write
,
BlockWrite
,
Lock
,
and
Kill
.
The menu item Tag
Access
(see Figure 6-6) adds a Mask field to the filtering operation, which allows the user to mask
individual "don't care" bits or segments of the matching pattern, where "1" identifies a bit of interest and "0" represents a
masked bit.
