The NFC emulated card selection method, the apparatus, the electronic device, and the storage medium provided in the embodiments of the present application are described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.
Fig. 1 is a schematic flowchart of an NFC emulated card selection method provided in an embodiment of the present application. The NFC emulated card selection method provided in the embodiment of the present application is described below with reference to fig. 1. As shown in fig. 1, the method includes:
step 101, receiving a target command sequence sent by a target NFC card reader within a target time period when the NFC card simulation function is in an off state and a signal sent by the target NFC card reader is detected.
Optionally, the NFC emulated card selection method provided in the embodiment of the present application is applicable to an NFC emulated card selection device.
Alternatively, the NFC analog card selection device may be an electronic device with an NFC function, such as a mobile phone, a tablet computer, a PDA (Personal Digital Assistant), a smart band, or a smart watch.
Before step 101, the NFC emulated card selection device may detect the state of its own NFC card emulation function.
Under the condition that the NFC card emulation function of the device is turned on, the NFC card emulation selection device may turn off the NFC card emulation function of the device in response to the second input after receiving the second input of the user, so that the NFC card emulation function of the device is in a turned-off state.
Under the condition that the self NFC card simulation function is in the closed state, the NFC simulation card selection device can further detect signals sent by the target NFC card reader.
It should be noted that the target NFC reader continuously and regularly sends out a signal under the normal power-on operation condition. The signal is a field strength signal.
The signal emitted by the target NFC reader may include the following commands defined by the ISO14443 protocol:
FIELD ON
REQA:REQuest command,Type A
REQB:REQuest command,Type B
REQF:REQuest command,Type F
FIELD OFF
the commands all belong to the card searching command.
Optionally, the target NFC card reader may be a card reader in the form of a pos (point of sales) machine or the like.
The NFC emulated card selection device may detect a signal sent by the target NFC card reader when a distance between the NFC emulated card selection device and the target NFC card reader is less than a first distance threshold.
A first distance threshold, corresponding to the target NFC reader, is determined by the target NFC reader.
In the case where the signal emitted by the target NFC card reader is not detected, the NFC emulated card selection device may continue to detect the signal emitted by the target NFC card reader.
When a signal sent by the target NFC card reader is detected, the NFC analog card selection device may start receiving and analyzing the signal sent by the target NFC card reader until the time length for receiving the signal reaches a preset time length, so as to obtain a plurality of commands.
And the target time period is a time period with the time when the NFC card simulation function is in the closed state and the signal sent by the target NFC card reader is detected as the starting time and the time length is the preset time length.
The preset time period can be preset according to actual conditions, for example, 100 ms. The embodiment of the present application is not particularly limited to a specific value of the preset duration.
Based on the respective commands obtained for the target time period, a target command sequence may be obtained.
Optionally, each command obtained in the target time period exhibits periodicity, and each command in one complete period may be extracted to obtain a target command sequence.
For example, the commands obtained in the target time period are: FILED ON- > REQA- > REQB- > REQA- > FILLED OFF- > FILLED ON- > REQA- > REQB- > REQA- > FILLED OFF; one full cycle of commands includes FILED ON- > REQA- > REQB- > REQA- > FILED OFF, so the target command sequence is FILED ON- > REQA- > REQB- > REQA- > FILED OFF.
And 102, under the condition that the target command sequence is matched with the stored target information, setting a target NFC simulation card corresponding to the target information as a default NFC simulation card and starting an NFC card simulation function.
Optionally, the card searching instruction issued by different target NFC card readers is formed by combining different commands, and the target command sequence may characterize the target NFC card reader.
For example, the target NFC reader a issues various commands in the following order: FILED ON- > REQA- > REQB- > REQA- > FILLED OFF- > FILLED ON- > REQA- > REQB- >
REQA- > FILED OFF; the target NFC card reader B issues the commands in the following order: FIELD ON- > REQA- > REQA- > FIELD OFF- > FIELD ON- > REQA- > REQA- > FIELD OFF; therefore, the card searching commands sent by the target NFC card reader A and the target NFC card reader B are combined by different commands, so that different target NFC card readers can be distinguished through a target command sequence.
Alternatively, based on the target command sequence, a feature describing a combination formed by each command in the target command sequence, for example, a combination manner of the commands, may be extracted as feature information of the target NFC card reader that issued the target command sequence.
