Attaching electronic tags to objects is a problem worth studying. Because the material of the object is different, the application situation is different, and so on, all need different electronic label paste way, which needs to do a lot of practical experiments before the specific application. But the following two principles are certain:

1.Electronic tags cannot be directly attached to conductive objects such as metal or human body, and the distance between them needs to be determined by experiments.

2.Electronic tags and read and write microwave antenna can not exist between conductive objects such as metal, human body, or very thick walls and other barriers to the radio waves.
