Abstract
The disclosure relates to duplication of a near field communication (NFC) card, and an operating method for an electronic device may comprise: detecting a tag of the NFC card; obtaining at least one parameter related to the NFC card; and based on the NFC card satisfying a specified condition, producing a duplicate card of the NFC card by storing the at least one parameter. The specified condition may include the features wherein the NFC card is a designated type of a card and the NFC card uses a default key.
Claims20
A method of operating an electronic device, the method comprising:
- detecting tagging of a Near Field Communication (NFC) card;
- acquiring at least one parameter related to the NFC card;
- and
- based on the NFC card satisfying a specified condition, generating a copy card of the NFC card by storing the at least one parameter,
- wherein the specified condition comprises an NFC card being of a specified type and an NFC card using a default key.
An electronic device comprising:
- a wireless communication circuit configured to support a Near Field Communication (NFC) protocol;
- a display;
- a processor operatively connected to the wireless communication circuit and the display;
- and
- a memory operatively connected to the processor,
- wherein the memory stores instructions which, when executed, cause the processor to:
- receive a first input for registering an external card supporting NFC in the electronic device,
- receive Radio Frequency (RF) parameters including an Answer to Request Acc. (ATQA), a Selection Acknowledge (SAK), and a Unique Identifier (UID) from the external card through the wireless communication circuit, based on at least a portion of the first input,
- store the RF parameters in the processor,
- determine whether the card is a specified type of card, based on the received SAK,
- duplicate a data block from the card using a default key, based on at least some of a determination result,
- receive a second input making a request for activating the card after duplicating the data block,
- access at least some of the stored RF parameters, based on at least a portion of the second input,
- configure at least some RF parameter used by the wireless communication circuit, based on at least some of the stored RF parameters, and
- communicate with an external electronic device through the wireless communication circuit.
A method of operating an electronic device, the method comprising:
- based on a copy card being selected by a user and an original card of the copy card being a specified type of card, identifying that the copy card is generated based on information which can be acquired without any authentication using a key,
- changing a configuration of a near field communication controller (NFCC) to use at least one parameter related to the stored copy card, and
- transmitting the at least one parameter to an external reader device through the NFCC.
