When receiving the Select command:

●

if the UID is equal to its own UID, the LRI2K enters or stays in the Selected state and

sends a response.

●

if the UID does not match its own, the selected LRI2K returns to the Ready state and

does not send a response.

The LRI2K answers an error code only if the UID is equal to its own UID. If not, no response

is generated.
