=head1 DESCRIPTION
-This module uses L<RFID::Biblio::Reader::Serial> over USB/serial adapter
+This module uses L<Biblio::RFID::Reader::Serial> over USB/serial adapter
with 3M 810 RFID reader, often used in library applications.
This is most mature implementation which supports full API defined
-in L<RFID::Biblio::Reader::API>. This include scanning for all tags in reader
+in L<Biblio::RFID::Reader::API>. This include scanning for all tags in reader
range, reading and writing of data, and AFI security manipulation.
This implementation is developed using Portmon on Windows to capture serial traffic
