Client mode (
HTTP Client
):
In this mode after reading the tag the module automatically connects to the server and
sends the data about the tag to the proprietary server resource (by HTTP GET). Ad the
answer can be retrieved information about the state of the LED, buzzer, LCD, etc. The
advantage of this mode of operation is that immediately after reading the card the
module itself sends the code to the server or control application. An example might be
writing to the database or file on the server the read rfid tag, the reader MAC number,
and read time.
