Abstract

An electronic device performs near field communication (NFC) functions. An operating method of the electronic device includes detecting an attachment of a first NFC tag which uses a first radio frequency signal type (RF signal type), checking whether to exclude the first NFC tag from a recognition of the NFC device in response to the attachment of the first NFC tag, and when the first NFC tag is excluded from the recognition of the NFC device, setting based on the checking a radio frequency signal type of the electronic device so as not to respond to a radio frequency signal of the first radio frequency signal type.

First claim

What is claimed is:

1. An operating method of an electronic device which includes a near field communication (NFC) device, the method comprising:
detecting an attachment of a first NFC tag which uses a first radio frequency signal type;
checking whether to exclude the first NFC tag from a recognition of the NFC device in response to the attachment of the first NFC tag; and
when the first NFC tag is to be excluded from the recognition of the NFC device, setting, based on the checking, a radio frequency signal type so as not to respond to a radio frequency signal of the first radio frequency signal type.

2. The method of claim 1 , further comprising:
upon receiving a first radio frequency signal from an NFC reader which uses the first radio frequency signal type, not responding to the first radio frequency signal.

3. The method of claim 1 , further comprising:
upon receiving a second radio frequency signal from an NFC reader which uses a second radio frequency signal type different from the first radio frequency signal type, communicatively connecting to the NFC reader in response to the second radio frequency signal.

4. The method of claim 1 , wherein the detecting of the attachment of the first NFC tag includes:
checking an existence of the first NFC tag;
when an attachment time of the first NFC tag is greater than a reference time, notifying of a long-term attachment of the first NFC tag; and
after notifying of the long-term attachment, receiving an attachment maintenance signal.

5. The method of claim 1 , wherein the checking whether to exclude the first NFC tag includes:
displaying a notification for checking whether to exclude the first NFC tag from the recognition of the NFC device.

6. The method of claim 1 , further comprising:
when the first NFC tag is to be excluded from the recognition of the NFC device, setting based on the checking the radio frequency signal type so as to send a radio frequency signal of a second radio frequency signal type different from the first radio frequency signal type.

7. The method of claim 6 , further comprising:
when a response signal is received from a second NFC tag in response to the radio frequency signal of the second radio frequency signal type, communicatively connecting to the second NFC tag.

8. The method of claim 1 , wherein the first NFC tag is a radio frequency card inserted in a case of the electronic device.

9. An electronic device, comprising:
a near field communication (NFC) device; and
a processor that executes instructions, wherein, when executed by the processor, the instructions cause the electronic device to:
detect an attachment of a first NFC tag which uses a first radio frequency signal type;
check whether to exclude the first NFC tag from a recognition of the NFC device in response to the attachment of the first NFC tag; and
when the first NFC tag is to be excluded from the recognition of the NFC device, set, based on the checking, a radio frequency signal type so as not to respond to a radio frequency signal of the first radio frequency signal type.

10. The electronic device of claim 9 , wherein, when executed by the processor, the instructions further cause the electronic device to:
upon receiving a first radio frequency signal from an NFC reader which uses the first radio frequency signal type, not respond to the first radio frequency signal.

11. The electronic device of claim 9 , wherein, when executed by the processor, the instructions further cause the electronic device to:
upon receiving a second radio frequency signal from an NFC reader which uses a second radio frequency signal type different from the first radio frequency signal type, communicatively connect to the NFC reader in response to the second radio frequency signal.

12. The electronic device of claim 9 , wherein detection of the attachment of the first NFC tag includes:
checking an existence of the first NFC tag;
when an attachment time of the first NFC tag is greater than a reference time, notifying of a long-term attachment of the first NFC tag; and
after notifying of the long-term attachment, receiving an attachment maintenance signal.

13. The electronic device of claim 9 , further comprising:
a display, wherein checking whether to exclude the first NFC tag includes:
displaying on the display a notification for checking whether to exclude the first NFC tag from the recognition of the NFC device.

14. The electronic device of claim 9 , wherein, when executed by the processor, the instructions further cause the electronic device to:
when the first NFC tag is to be excluded from the recognition of the NFC device, set based on checking the radio frequency signal type so as to send a radio frequency signal of a second radio frequency signal type different from the first radio frequency signal type, and
when a response signal is received from a second NFC tag in response to the radio frequency signal of the second radio frequency signal type, communicatively connect to the second NFC tag.

15. The electronic device of claim 9 , further comprising:
a case, wherein the first NFC tag is a radio frequency card inserted in a case of the electronic device.
