Abstract
A target radio frequency identification (RFID) device may include a receiver to receive valid bits common to a first set of random numbers and to receive a signal indicating a change in a number of time slots from a first number of a plurality of time slots to a second number of a plurality of time slots in which the target device may respond. The target device may include processing circuitry to generate a random number, to determine if the random number is in the first set, to generate a random value, and to randomly select a time slot. The target device may further include a transmitter to communicate a response if the random number is determined to be in the first set, and to communicate the random value during the randomly selected time slot.
