Micro-Letter Fingerprint Payment opening method
1 we open the micro-letter click on the interface of "settings-account and security-fingerprint-entry" so we will be prompted to enter your own fingerprint, so that after the recording of the payment of micro-letter will automatically prompt the opening of the fingerprint payment function. (pictured below)
2 After a simple fingerprint verification, you can open the net after the purchase of the time will be able to pay with fingerprints. (pictured below)
OK this micro-letter fingerprint payment function is open, in fact, is the version of the problem, the new version of this feature.
