The PN544 chip from NXP is the “world’s first” truly industry standard near field communication (NFC) controller, delivering a fully compliant platform for handset manufacturers and operators to introduce next generation NFC devices and services. It is based on the latest NFC specifications by the European Telecommunications Standard Institute (ETSI). It enabes mobile phone users to access a new range of contactless applications such as mobile payments, transport and event ticketing, as well as data sharing directly from the mobile phone SIM (subscriber identity module) for improved on-the-go experience. It is fully compliant with all released NFC specifications on the single wire protocol (SWP) connection with the SIM and the host controller interface (HCI). In addition, NXP worked closely with leading SIM card manufacturers such as Gemalto, Oberthur Technologies and Giesecke and Devrient to ensure SWP interface interoperability including support of the MIFARE technology. The NFC controller is fully backwards compatible and interoperable with existing contactless infrastructure for payments and ticketing, already in place across the world. It has been designed to support the three main architectures which are used to secure NFC transactions, including the secure element within the universal integrated circuit card (UICC), within the SD card and within the mobile handset.
