Embodiment Construction

[0013] While the invention is susceptible to various modifications and alternative forms, its details are shown by way of example in the drawings and will be described in detail. It should be understood, however, that the intention is not to limit the invention to the particular embodiments described. On the contrary, the intention is to cover all modifications, equivalents and alternatives falling within the spirit and scope of the invention as defined by the appended claims.

[0014] figure 1 is a flowchart illustrating a method of activating a communication device in the presence of a field generated by the NFC tag reader 100 . Step 105 detects the presence of a field generated by an NFC or RFID tag reader. figure 2 An example of a detection circuit is shown. If a field is detected, step 110 indicates the presence of the field to the associated communication device. Another step 115 switches the communication device into the appropriate mode according to the field gene...

Abstract

The present invention discloses a method and system for activating a communication device in the presence of a field generated by a near field communication (NFC) tag reader in a near field communication (NFC) environment. Automatically detects the presence of fields generated by NFC tag readers using detection circuitry. Once the field is detected, the presence of the field is signaled to the communication device associated with the NFC environment. The communication device is then automatically switched to the appropriate mode based on the field. The methods and systems of the present invention eliminate additional user interaction in pairing different communication devices in an NFC environment.

Description

technical field [0001] The present invention relates generally to near field communication (NFC), and more particularly to systems requiring activation in the presence of an NFC device. Background technique [0002] Near field communication plays a vital role in the current communication world where consumers are looking for easier ways to interact with the immediate environment and enable communication between their electronic devices role. NFC's intuitive operation changes the way you interact with technology by enabling easy wireless connectivity, securing most environments and reaping the full benefits of total connectivity. NFC is a standards-based short-range wireless connectivity technology that enables simple and secure two-way interaction between electronic devices, which allows users to perform contactless transactions, access digital content, and connect devices with a single touch. NFC uses electromagnetic waves in the radio frequency range and transmits inform...
