A communication method in a system having a reader and at least one transceiver, the method including the reader selecting a response signal strength level from a plurality of response signal strength levels; and establishing communication between the reader and the at least one transceiver at the selected response signal strength level.

Communication method having selectable response signal strength levels

An apparatus for providing a random bit stream includings a first provider for providing a clock signal, a second provider for providing a sample signal, an activator for activating the first and second providers such that a sampling edge of the sample signal is aligned to an edge of the clock signal. The apparatus further includes a sampler for sampling the clock signal responsive to the sampling edge of the sample signal and for generating a random bit dependent on the sampled state of the clock signal. Further, the apparatus includes a deactivator for deactivating the first and second providers. Successive random bits form a random bit stream.
