Abstract

The invention discloses a power supply control method for an NFC antenna, a computer storage medium, and a mobile terminal. The power supply control method for the NFC antenna includes the following steps: power-on information stored in a memory of the mobile terminal is obtained; and according to the power-on information, whether the mobile terminal is in a power-on state of abnormal restart or apower-on state of normal start is judged according to the power-on information, if the mobile terminal is the power-on state at the time of abnormally restarting, power supply to the NFC antenna is controlled to stop, and if the mobile terminal is in the power-on state during the normal start, power is controlled to be supplied to the NFC antenna. According to the power supply control method, power supply to the NFC antenna can be stopped when the mobile terminal is in the abnormal restarting, and the NFC antenna is prevented from being burnt to be damaged due to a short circuit of reversal connection between a user NFC contact and a battery.

Description

technical field [0001] The invention relates to the technical field of mobile terminals, in particular to a power supply control method for an NFC antenna, a computer storage medium and a mobile terminal. Background technique [0002] NFC (Near Field Communication, near-field communication technology) is a short-range high-frequency radio technology that generally operates at a frequency of 13.56MHz within a distance of 10 cm. With the rapid development of NFC technology and vigorous promotion by operators, more and more mobile terminals are equipped with NFC functions. At present, this technology is widely used in airport boarding verification, building access control keys, transportation cards, credit cards and payment cards, etc. [0003] In the prior art, in order to enable the NFC antenna to receive related signals more sensitively, the NFC antenna is often set on the back shell or the battery shell of the mobile terminal, and the NFC antenna needs to be set with corre...
