The invention relates to a gaming ticket comprising validation data which are printed on a face thereof and which are covered with at least one layer of ink which is opaque with respect to visible light. The second path is established in a procedure comprising the transmission of data from the first to the second master controller, a phase of simultaneous transmission of radio signals by the infrastructure on the first and second paths, then the suppression of the first path. Through the coordination, the low power communications system may be protected from potentially excessive interference from the overlying network andor user devices operating on that network while minimizing any impact on performance and capacity of the overlying network. The first agitator is configured to rotate. The current evaluation circuit can be activated by a circuit section for automatic deactivation before a read operation and be automatically deactivated directly after the read operation has ended.
