Abstract
A near field communication (NFC) device stores a plurality of digital emulated cards. When the NFC device detects the carrier field from an NFC reader, the NFC device enters a silent monitoring phase in which the NFC device records characteristics of a plurality of polling cycles of the NFC reader without responding to the NFC reader. The NFC device selects a digital emulated card based on the characteristics of the polling cycles. The NFC device presents the selected digital emulated card to the NFC reader.
Claims25
A method comprising:
- receiving, with an NFC device, a plurality of first polling cycles from an NFC reader without responding to the NFC reader;
- analyzing, with the NFC device, characteristics of the first polling cycles;
- selecting, with the NFC device, a digital emulated card from a plurality of digital emulated cards based on the characteristics of the first polling cycles;
- and
- presenting the selected digital emulated card to the NFC reader from the NFC device via NFC communication.

A method, comprising:
- storing a plurality of digital emulated cards in an NFC device;
- storing, in the NFC device, profile data associated with a plurality of types of NFC readers;
- receiving, with the NFC device, a plurality of first polling cycles from an NFC reader without responding to the NFC reader;
- matching the NFC reader to one of the types of NFC readers in the profile data based on characteristics of the first polling cycles;
- selecting one of the digital emulated cards from the plurality of digital emulated cards based on the matching;
- and
- presenting the selected digital emulated card to the NFC reader from the NFC device via NFC communication.
20-21. (canceled)
An NFC device, comprising:
- an NFC antenna;
- a memory configured to store digital emulated card data of a plurality of digital emulated cards;
- and
- a controller coupled to the memory and the NFC antenna and configured to implement a silent monitoring phase responsive to the NFC antenna receiving a carrier field from an NFC reader.
