× Winding Process
It is a process that combines an antenna and an IC loop to form a module. It takes some time to mount modules one by one on a thin board. Therefore, high costs are not suitable for mass production. However, compared with other manufacturing processes, the tag communication distance is improved.
× Etching Process
It is a process of forming an antenna by etching aluminum or copper film on the pet Film Board. Figure 4 shows an item (using an etching antenna in an IC circuit). Because it can be made into a bucket, it can be processed by a high-speed processing machine, which is suitable for mass production, the price is also relatively low, which is currently the mainstream production method.

× Printing Process
It is a process that uses conductive ink (silver foil, etc.) for printing and generates an antenna. It is expected to become the cheapest production method. However, due to the weekly wave number and electric conductivity problems, the tags of the UHF Band are only productized, but the supply is not stable yet.
