The innovation focused on embedding NFC tag typically available in plastic cards form factor into an ordinary SIM (subscriber identity module) card of mini SIM or micro SIM size, effectively known as NFC-SIM. NFC-SIM draws electricity from mobile phone’s SIM slot via UICC contact pad to become an NFC tag to be read by NFC terminals despite being obstructed by battery and the metal casing of the mobile phone. This is the most difficult and challenging part faced by even the largest semiconductor companies, cell phone makers, and mobile device manufacturers.
The operation of NFC-SIM is a simple plug and play to any mobile phone, regardless of its model and built. Once NFC-SIM card is inserted, the mobile phone will be able to access menu with application written into the SIM using STK or WIB2.0. Ultimately, this SIM card empowers any mobile phones as a media for e-wallet/e-cash carrier.
