Predeterminated voltage is Y3 ....
S200, the change frequency according to the NFC interface antenna leads voltage difference of acquisition within the predetermined time, inquiry pair
The predeterminated voltage answered.
When intelligent terminal gets change frequency C of the NFC interface antenna leads voltage difference within the predetermined time,
The change frequency phase with the NFC interface antenna leads voltage difference of acquisition within the predetermined time is searched in the mapping table
Corresponding predeterminated voltage.That is, it is judged that change frequency C belongs to which of mapping table range, it is corresponding as 0≤C < X1
Preset voltage value be Y1, as X1≤C < X2, corresponding preset voltage value be Y2, as X2≤C < X3, corresponding default electricity
Pressure value is Y3 ....
The supply voltage of the NFC is arranged according to the predeterminated voltage inquired for S300, the intelligent terminal.
When the preset voltage value that intelligent terminal inquires is Y1, then Y1 is set by the supply voltage of NFC；When intelligent end
When the preset voltage value that end inquires is Y2, then Y2 is set by the supply voltage of NFC；When the default electricity that intelligent terminal inquires
When pressure value is Y3, then Y3 is set by the supply voltage of NFC ... in this way, the NFC of the intelligent terminal in the present invention is in communication
It does not need to keep higher traffic rate, does not need to keep higher voltage yet, but be arranged according to virtual condition reasonable
Traffic rate and supply voltage.
