METHOD AND SYSTEM FOR DETECTING AN END OF TRANSACTION FOR CONTACTLESS TRANSACTIONS ON A MOBILE DEVICE
First Claim
1. A system for contactless transaction validation suitable for use in a mobile device, comprising:
- a Near Field Communication (NFC) modem for receiving radio frequency (RF) signals associated with a contactless data transaction;
an Universal Integrated Circuit Card (UICC) containing NFC applications, called NFC-UICC, communicatively coupled to the NCF modem for providing security to the contactless data transaction; and
an application processor communicatively coupled to the NFC-UICC for informing the mobile device of an end of transaction in the contactless data transaction,wherein the NFC-UICC detects an end of transaction from the NFC modem via state transitions and informs the application processor via a status word that an end of transaction for the contactless data transaction has been confirmed.

Abstract
A system (100) and method (200) for NFC/UICC and NFC/RFID contactless transaction validation suitable for use in a mobile device (110) is provided. The system can include a Near Field Communication (NFC) modem (140), a NFC Universal Integrated Circuit Card (NFC-UICC) (130), and an application processor (120) for informing the mobile device of an end of transaction in the contactless data transaction. The NFC-UICC can detect the end of transaction from the NFC modem via state transitions and informs the application processor via a status word that an end of transaction for the contactless data transaction has been confirmed. The system can include an NFC application (132) for monitoring data communication and an NFC-UICC toolkit application (136) for providing proactive command support to the mobile device and providing notification through the status word.

13. A system for enhanced read complete indication, comprising:
-
a mobile device having a phone card for providing contactless data transactions and presenting transaction events through a user interface; and a reader external from the mobile device that reads the phone card information from the mobile device when the mobile device is in proximity to a radio frequency (RF) field of the reader, wherein, upon completion of a contactless data transaction, the reader sends an acknowledgment to the mobile device confirming that information from the phone card has been successfully read, and the user interface informs the user of the transaction status. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
