Biometric reader in card

This invention describes a system for secure digital transactions using a smart card with a built-in fingerprint reader. A separate device, like a smartphone, is used to select transaction details and send them to the card. When the card is then used for a payment, it first scans the user's fingerprint to confirm their identity against stored data, and then processes the transaction according to the details it received.

Why it matters: Filed as biometric payment cards were emerging. Since 2020, miniaturized biometric sensors and secure element technology have advanced, making integration into a standard card form factor more cost-effective and reliable for mass production.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: SpecializedMiniaturized biometric reader, custom card electronics.
