Abstract
A near-field communication (NFC) device is described. The NFC device includes an antenna configured to radiate an electromagnetic field. The NFC device also includes electronic circuitry coupled to the antenna. The electronic circuitry is configured to receive first data from a unidirectional tag device within a transmission limit. The electronic circuitry is also configured to receive second data from at least one bidirectional tag device after the transmission limit.
Claims14
A near-field communication (NFC) device, comprising:
- an antenna configured to radiate an electromagnetic field;
- and
- electronic circuitry coupled to the antenna, wherein the electronic circuitry is configured to:
- receive first data from a unidirectional tag device,
- determine the unidirectional tag device has ceased performing any transmission upon receiving a threshold number of transmissions from the unidirectional tag device,
- send a command in response to the determination, and
- receive second data from at least one bidirectional tag device after sending the command.
A method performed by a near-field communication (NFC) device, the method comprising:
- radiating an electromagnetic field;
- receiving first data from a unidirectional tag device;
- determining the unidirectional tag device has ceased performing any transmission upon receiving a threshold number of transmissions from the unidirectional tag device;
- sending a command in response to the determination;
- and
- receiving second data from at least one bidirectional tag device after sending the command.
A non-transitory tangible computer-readable medium storing computer executable code, comprising:
- code for causing an electronic device to radiate an electromagnetic field;
- code for causing the electronic device to receive first data from a unidirectional tag device;
- code for determining the unidirectional tag device has ceased performing any transmission upon receiving a threshold number of transmissions from the unidirectional tag device;
- code for sending a command in response to the determination;
- and
- code for causing the electronic device to receive second data from a bidirectional tag device after sending the command.
An apparatus, comprising:
- means for radiating an electromagnetic field;
- means for receiving first data from a unidirectional tag device;
- means for determining the unidirectional tag device has ceased performing any transmission upon receiving a threshold number of transmissions from the unidirectional tag device;
- means for sending a command in response to the determination;
- and
- means for receiving second data from a bidirectional tag device after sending the command.
