Only active tags are automatically pinged by the system.
I can't agree with that, Roger (but maybe I was causing confusion by using the words "automatically pinged").
Surely passive tags
do have to be interrogated by a reader in order to give up (return) their information. Passive tags are often embedded in "stores" items, such as linen in the laundry, and trays (
etc.) in CSSD. But they only respond when asked ("pinged").
