Benefits of technology

[0007]Example embodiments provide a method of operating an NFC device capable of reducing communication errors without increasing occupied area.
[0008]Example embodiments provide an NFC device capable of reducing communication errors without increasing occupied area.
[0020]In some embodiments, the NFC device may increase a bandwidth of the NFC device during the signal transmission interval by changing the RF configuration parameter, when the NFC reader does not recognize the response.
[0034]Accordingly, when an NFC device communicates with an NFC reader and communication errors occur in a signal transmission operation or signal reception operation, an NFC chip in the NFC device may change an RF configuration parameter of a resonance unit in the NFC device and the NFC device may retry communication with the NFC reader. Therefore, the NFC device may enhance communication performance without increasing occupied area.

Problems solved by technology

When the NFC devices communicate with the NFC readers, errors due to various causes may occur.
Accordingly, when an NFC device communicates with an NFC reader and communication errors occur in a signal transmission operation or signal reception operation, an NFC chip in the NFC device may change an RF configuration parameter of a resonance unit in the NFC device and the NFC device may retry communication with the NFC reader.

Abstract

A method of operating a near field communication (NFC) device includes receiving, by the NFC device, a first signal from an NFC reader, transmitting, by the NFC device, a response to the first signal to the NFC reader and changing selectively, by the NFC device, a radio frequency (RF) configuration parameter associated with signal transmission operation during a signal transmission interval, based on determining whether the NFC reader recognizes the response.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims priority under 35 USC §119 to Korean Patent Application No. 10-2014-0099876, filed on Aug. 4, 2014, in the Korean Intellectual Property Office (KIPO), the contents of which are herein incorporated by reference in their entirety.BACKGROUND[0002]1. Technical Field[0003]Embodiments of the inventive concept described herein relate to near field communication (NFC). In particular, the inventive concepts relate to a method of operating an NFC device and an NFC device.[0004]2. Description of the Related Art[0005]NFC technology is a type of wireless communication technology. Recent developments in NFC technology have resulted in NFC devices being used extensively in mobile devices.[0006]NFC devices communicate with NFC readers with resonance frequency. When the NFC devices communicate with the NFC readers, errors due to various causes may occur.SUMMARY[0007]Example embodiments provide a method of operating an NFC device cap...
