In sports timing systems, P2P communication is used at low frequency bandwidths (under 135 KHz) between tags and readers in the RFID field. However, in such cases, collisions tend to occur when a reader deals with multiple RFID tags simultaneously. To overcome this issue, a sports timing system including a Multi Reader Controller (MRC) loaded with an advanced multiple reader algorithm and application was created and applied at large-scale citizens' marathon events. In these cases, a large number of people pass over the installed urethane type's antenna mat continually during a short period of time. This study verified the superiority of the improved algorithm and application through the on-the-spot application of the multi reader algorithm and application program, which allows us to smoothly measure runners' times through multiaccess reading for rapid collision avoidance.
