Abstract
A terminal for contactless communication with portable objects comprises a wave pickup device responsive to the magnetic component of an electromagnetic field, and a receiver which cooperates with the wave pickup device to receive and amplify signals picked up thereby. The wave pickup device comprises at least two distinct and adjacently disposed wave pickup elements spaced apart by a predetermined gap, and a discriminator for deriving a discrimination signal from the signals picked up by each of the wave pickup elements during a given period. The discrimination signal indicates which one of the wave pickup elements has received a signal of greater amplitude.
