The fingerprint image is collected mainly through the Sensor, and the fingerprint algorithm chip is used for fingerprint processing and comparison. If the comparison is passed, the financial IC card or IC access control attendance recognition function can be connected to conduct normal transactions or open the door; if the comparison fails, the financial IC or IC access control card function cannot be used.

In the case of supporting contactless and fingerprint verification, the fingerprint ID card application can be said to be almost perfect: 

The fingerprint is entered when the card is issued, and the fingerprint is used when it is used. There is no need to worry about lost. The fingerprints of the administrator and the user can be entered, so that the fingerprint card can be recycled and reused, which is environmentally friendly and energy-saving.

The fingerprint card reads and enters the fingerprint through NFC induction, and can be sensed in the following 3 ways:
