Abstract: An NFC tag verification method is provided. The method is applied to a first electronic device, and includes: detecting NFC tag information of a second electronic device; performing verification on the NFC tag information based on a locally stored first verification list, to obtain a first verification result; if the first verification result is that the verification succeeds, starting to run an application service associated with the NFC tag information; sending the NFC tag information to a cloud server; receiving a second verification result obtained by the cloud server by performing verification on the NFC tag information; and if the second verification result is that the verification fails, stopping running the application service. In the solution of embodiments of this application, when verification is performed on an NFC tag, the application service is first started to run after local verification succeeds, and then cloud verification is performed.
