SmartMetric, Inc. announced that it has successfully completed the manufacture of its sub micro nano fingerprint scanner that fits inside a credit card. This allows the card holder's fingerprint to be used as the ultimate security key to unlock the credit card as it is inserted into a credit card reader or ATM. Taking credit card security beyond the risky and unsafe four digit PIN code, SmartMetric has developed a super small and thin fingerprint scanner that brings high level biometric security to the credit card.

Some of the recent advancements SmartMetric has achieved in its now Gen4 biometric credit card technology is an inbuilt physical sensor that determines if an actual human live fingerprint is being used. This protects the card from being used by, for instance, a fake silicon fingerprint replica. In addition, the SmartMetric fingerprint electronics is powered by an extremely thin hybrid nano rechargeable battery, allowing the card to be used in card readers at such places as gas station pumps and ATMs that take the card wholly into the card reader.

The SmartMetric biometric fingerprint scanning credit card is unique in the world in that it is the first and only such card that has an inbuilt rechargeable battery, allowing the card to be used at any type of credit card reader including contactless and ATM readers.
