The induction area of the reader is divided into working area, critical area and

non-working area. In practical application, the recommended working area is most stable

for the reader. When a tag is located in the non-working area, the reader cannot have

wireless communication with the tag. The critical area, located between the working area

and the non-working area, has instable operation and can easily cause data error. When the

reader runs in the metallic working environment, the working area will be weakened and

the practical test shall prevail at this moment. The relation among the working areas of the

reader is as shown in Tab. 3.1.

In practical application, the field communication may be influenced by various

factors. Therefore, in order to ensure the reliability of RFID read-write operation, it is

suggested to design the read-write distance of the RFID application system according to

the recommended working Field .

Note: the division of the induction field is greatly related to the tag, and the purpose of above areas is to

explain the application principle, and the practical measurement is required for specific implementation.

3.1.3 Tag installation orientation and movement direction

When the tag is parallel with the reader antenna, the tag can obtain the maximum

energy from the magnetic field and better communicate with the reader, so the tag must be

installed in parallel with the reader antenna, with the front face orientating to the reader.
