$SMME SMARTMETRIC is based in the USA with marketing and engineering in various parts of the World. SmartMetric has created a fingerprint scanner that fits inside a credit and debit card and is used to provide biometric protection for these cards. The card user simply touches a square sensor on the card’s surface and in less than 0.25 seconds the card’s internal fingerprint scanner reads the card user’s fingerprint and if the fingerprint matches the card is immediately turned on.
