7.5
LoginRead
The purpose of the LoginRead command is to release the read protection on all read protected
data blocks within the user memory. A tag in the Selected state will respond with a SOF pattern
if the transmitted read password matches the data stored in the tag’s system memory block
36hex (Read PWD). In the case of a non-matching read password the tag will reply with a SOF
pattern followed by an error code. After a successful LoginRead command, all read protected
memory blocks may be read normally. This positive login status remains valid until a new tag is
selected or the tag is reset.
7.6
LoginWrite
The purpose of the LoginWrite command is to release the write protection on all write protected
data blocks within the user memory. A tag in the Selected state responds with a SOF pattern if
the transmitted write password matches the data stored in the tag’s system memory block 37hex
(Write PWD). In the case of a non-matching write password the tag will reply with an SOF fol-
lowed by an error code. After a successful LoginWrite command any write protected memory
block may be modified, as long as the addressed memory block is not already locked. The posi-
tive login status is valid until a new tag is selected or the tag is reset.
