SIM pass technology integration the DI card and SIM card technology, called dual-interface SIM card. SIM pass antenna is based on RFID radio frequency identification technology. by the transformer of coupling matching to make communication hardware processing program, and the completion of the data transfer process via processor communication instruction, hardware and software environment through RFID modulation processing, and adjustment of matching circuit design.The most effective SIM pass antenna should consider the effectiveness and stability of polymer, interference-resist materials. And the stability of manufacturing process is regarded as one key to product performance index. For product quality, it is a guarantee to improve the targeted evaluation and inspection equipment. Sunshine worked together with Woqi to fully explore suitability between SIMPASS antenna and SDPASS, antenna environment.Up to now, SIMPASS/SDPASS is widely used in the school, bus or other fields as One Card
