SWITCHING BETWEEN NEAR-FIELD COMMUNICATION SYSTEMS
First Claim
Patent Images
1. A mobile device, comprising:
- a first Near Field Communication (NFC) system integrated into the mobile device and including an antenna and an NFC controller and configured to detect an RF field of a terminal or an NFC tag; and
a second NFC system configured to insert into an external port of the mobile device and including an NFC secure element, wherein the secure element is configured to execute an NFC transaction using the antenna of the first NFC system based on communication received by the terminal or information stored in the NFC tag.

Abstract
In some implementations, a method receiving, from a NFC system integrated into a mobile device, a notification of a detected RF field from a terminal or an NFC tag. A transaction element inserted into an external port of the mobile device receives the notification. A transaction is performed using information and a transaction application stored in a secure element in the transaction card.
