on RFID Tag(s).
The reader provides three levels of access to RFID Tag(s):
Browser-Based InterfaceA web browser controls high-level reader operations via a
Java applet.
See Using the Browser-Based Interface
of this manual.
RQLAn intermediate form of accessing the tags is available via the RQL (reader
query language) application, operating similarly to an SQL (structured query
language) database server.
See the Reader Query Protocol and RQL
manual or download it from ThingMagic at

APIFinally, low-level APIs (application programming interface) provide fine control
over all aspects of the reader. The reader supports UHF antennas, which are
available separately. The reader supports multiple configurations of UHF antenna
ports and transfers data to a remote computer over a network connection.
