| 摘要 |
The invention concerns a system for detecting multiple tags in a detection zone. The system includes an electronic tag detection system having first and second field generators, each having a respective antenna for generating an electromagnetic field in a detection zone defined between the antennas. Additionally, at least one of the field generators can be responsive to a presence of at least two electronically detectable tags in the detection zone, for varying an intensity of at least one of the electromagnetic fields.
