System and method for reading one or more RFID tags in a metal cassette with an anticollision protocol
First Claim
1. A reading apparatus for objects with at least one RFID tag, said objects being placed in a cassette, said apparatus comprising at least one tunnel-shaped element into which said cassette is placed, said at least one tunnel-shaped element comprising at least one antenna and an RFID reader, said at least one antenna comprising at least three coils formed by a continuous wire, each coil comprising several windings, said at least three coils being distributed along and around said at least one tunnel-shaped element, wherein the windings of the at least three coils are perpendicular to the at least one tunnel-shaped element'"'"'s main axis and the at least three coils are spaced apart from each other at regular intervals along said at least one tunnel-shaped element and are parallel to each other, and wherein the reading apparatus reads one or several low-frequency tags operating at a frequency range of between 124 and 135 kHz, which tags are rod-shaped and have an anti-collision protocol and which are attached to or incorporated into objects consisting of metal and/or synthetic materials, said rod-shaped tags being disposed with their longitudinal axis in a direction within a range +/−
