Patent attributes
A mobile device includes a wireless transceiver, a host processor, a secure element (SE), and a near field communication (NFC) system having an NFC transceiver and an NFC controller implementing a contactless front end. The contactless front end routes a near field communication related to a payment transaction between the NFC system and the SE without going to or from the host processor. The contactless front end routes a near field communication not related to a payment transaction, but requiring a security function, between the NFC system and the SE without going to or from the host processor. The contactless front end routes a near field communication not related to a payment transaction, and not requiring a security function, between the NFC system and host processor without going to or from the SE.
