The fingerprint module is applied to the card

Fingerprint modules will replace passwords, and with the development of innovative technology, BNP Paribas has launched Visa Premier, a bank card that can be identified with fingerprints, in France. The specific usage of the fingerprint card is as follows: after the user receives the fingerprint card, insert the card into the card reader to record the fingerprint, the user can choose a fingerprint to record five times, and the machine will prompt for confirmation after each successful registration. For security reasons, users still need to enter a password when making the first payment, and then they can use their fingerprints to pay directly without the upper limit of the amount. When paying, place your finger on the fingerprint frame of the card, and you can pay a few centimeters away from the merchant's cash register.
