Abstract
A method for coordinating reader transmissions according to one embodiment includes, at a first reader, receiving from a second reader a request to transmit to a radio frequency identification tag; and if the first reader is transmitting, sending a denial of the request from the first reader to the second reader. A method for coordinating reader transmissions according to another embodiment includes from a first reader, sending to a plurality of readers a request to transmit to a radio frequency identification tag; waiting for responses from the plurality of readers; if a denial of the request is received by the first reader from any of the readers, not transmitting to the radio frequency identification tag; and if no denial of the request is received by the first reader from any of the readers, transmitting to the radio frequency identification tag. Additional systems, methods and computer program products are presented.

19. A method for coordinating reader transmissions, comprising:
-
for a first of a plurality of readers, determining whether the first reader and any other of the readers interfere with each other; and storing a result of the determination; wherein the first reader sends a request to transmit to those readers determined to interfere with the first reader or vice versa prior to transmitting to a radio frequency identification tag; wherein if a denial of the request is received by the first reader from any of the readers receiving the request, not transmitting to the radio frequency identification tag; and wherein if no denial of the request is received by the first reader from any of the readers receiving the request, transmitting to the radio frequency identification tag. - View Dependent Claims (20, 21, 22, 23, 24, 25)

31. A computer program product comprising a computer readable medium having computer code thereon, which when executed by the computer causes the computer to:
-
determine whether a first of a plurality of computers and any other of the computers interfere with each other; and store a result of the determination; send a request to transmit from the first computer to those computers determined to interfere with the first computer or vice versa prior to transmitting to a radio frequency identification tag; not transmit to the radio frequency identification tag if a denial of the request is received by the first computer from any of the computers receiving the request; and transmit to the radio frequency identification tag if no denial of the request is received by the first computer from any of the computers receiving the request.
