SmartMetric, Inc. having spent years of research and development to perfect the miniaturization of electronic components along with the development of the SmartMetric card internal nano power management system, has created a biometric card that works with all credit card readers, including restaurants, store checkouts and ATM's. Other companies who have attempted to copy the SmartMetric biometric credit card have failed to have a card that works across all card readers. These imitators have not spent the years of R&D that SmartMetric has in developing an internal power system, nor do they have a rechargeable internal battery to enable the card to work without being held in the card reader. The other card companies, because they do not have an internal power source, use the power of the card reader to power the fingerprint reading processor.

This requires their card to be held in the card reader while a fingerprint scan of the card holder is done on their card. This failed system design by other biometric card companies means that the card will not work at ATM's and most EMV gas pumps that of course “swallow” the card, not permitting the user to hold the card's fingerprint sensor on the card for a fingerprint scan. Restaurants that take the card from the table and process the payment at their card reading station also will not be able to process these non-powered biometric cards, since such cards need to be held by the card holder when the card is inserted into the card reader.

Of course, restaurants that have a portable card reader that is brought to the table will work, but in markets such as the United States, it is a minority of restaurants that have portable to the table card readers.
