There are mainly several aspects:
1. Detection distance: 1.1-1.5 meters for AM tags, 0.7-0.9 meters for electromagnetic wave magnetic strips, because AM tags are more suitable for open stores with more traffic than electromagnetic wave magnetic strips in terms of detection distance.
2. Reusable: AM tags are not reusable, and electromagnetic wave magnetic strips are divided into reusable and permanent.
3. Material: The shell material of the AM label is polystyrene, and the electromagnetic wave is divided into cobalt-based and iron-based (the difference is that the first is not rusty and the other is easy to rust in wet areas)
4. Frequency: AM tags have a fixed frequency of 58KHz, while the principle of the magnetic strip is mainly to cut the magnetic field lines without frequency
