Systems and methods for operating a tag reader. The methods comprise: performing tag read operations by the tag reader to read tags; processing first information received from the read tags to identify which tags are newly detected tags; adding entries for the newly detected tags in a local list stored in a local memory of the tag reader; communicating second information at least identifying the newly detected tags from the tag reader to a remote computing device; receiving, by the tag reader, feedback information generated by the remote computing device which specifies at least a count of entries added to a remote list stored in a remote datastore based on the second information; and selectively outputting a notification from the tag reader based on the value of the count.
