Problems solved by technology

The connection between the metal contacts of the dual-interface IC card chip and the radio frequency identification antenna terminal is difficult, the production efficiency is very low, and the stability of the connection is poor, easy to fall off, and the service life is short, which cannot meet the application requirements.
Therefore, on the one hand, the market prospect of the dual-interface IC card is very broad; on the other hand, the manufacturing method of the dual-interface IC card is difficult in technology, and the production efficiency is low, and the dual-interface IC card has poor quality stability and short service life. , far from meeting the market demand for dual-interface IC cards
