3) Multi Once
The reader reads multiple tags repeating the read transaction until timeout. Upon timeout, it returns all results of
communication with tags to the host and finishes the transaction. If the reader does not detect any tag during the reading
time, it returns response meaning the number of tag = 0.
4) Multi Repeat
The reader reads multiple tags repeating the reading transaction until timeout. Upon timeout, it returns results of
communication with tags to the host and it starts another time period to repeat the transaction until termination command
has been sent. At each timeout, the reader returns all read tag’s results to the host. If it does not read any tag during each
time period, it returns response meaning the number of tag = 0.
